37. Direction: Read the following Caselet DI carefully and answer the following questions.In a shop, the shopkeeper sells 4 different brands of bulb and tube lights that is Syska, Philips, Bajaj and Havells. Total number of tube lights in shop is 500 and is 100% more than the number of bulbs in the shop. Number of tube lights of Havells is 150% of the bulbs of Syska which is equal to the bulbs of Bajaj available in the shop which is 80 in number. Number of bulbs of Philips is half of the number of bulbs of Syska. Number of tube lights of Philips is 40 more than the number of tube lights of Bajaj and number of tube lights of Syska is 20 less than the number of tube lights of Bajaj.

Question:

Find the difference between average of bulbs of Syska and Philips together to the average of tube lights of Bajaj and Havells.

A. 60

B. 50

C. 80

D. 70

E. 55

Solution

Number of tube lights is 100% more than the total bulbs in the shop

And, Number of tube lights = 500

So, Number of bulbs in the shops = (500 / 200) × 100 = 250

Bulbs of syska = Bulbs of Bajaj = 80

Tube lights of Havells = (150 / 100) × 80 = 120

Bulbs of Philips = (1 / 2) × bulbs of syska

⇒ (1 / 2) × 80 = 40

Let the tube lights of bajaj be x

So, tube light of Philips = x + 40

And, tube light of syska = x – 20

And according to Caselet

⇒ x – 20 + x + 40 + x + 120 = 500

⇒ 3x + 140 = 500

⇒ x = 120

So, the tube lights of Bajaj = 120

Tube light of Philips = 160

Tube light of syska = 100

Bulbs of Havells = 250 – (80 + 40 + 80) = 50

 BulbsTube lights
Syska80100
Philips40160
Bajaj80120
Havells50120

According to question,

Average of bulbs of syska and Philips = (80 + 40) / 2 = 60

Average of tube lights of Bajaj and Havels = (120 + 120) / 2 = 120

⇒ Required difference = 120 – 60 = 60∴ The difference between the asked averages is 60

Number of tube lights of Philips is 40 more than the number of tube lights of Bajaj and number of tube lights of Syska is 20 less than the number of tube lights of Bajaj.

Question:

Find the ratio between total number of Havells items in the shop to the total number of Philips items in the shop.

A. 13 : 17

B. 17 : 20

C. 20 : 19

D. 20 : 17

E. 13 : 19

Solution

Number of tube light is 100% more than the number of bulbs in the shop

So, total bulbs in the shops = 500 / 200 × 100 = 250

Bulbs of syska = bulb of bajaj = 80

Tube lights of Havels = 150 / 100 × 80 = 120

Bulbs of Philips = (1 / 2) × bulbs of syska

= (1 / 2) × 80 = 40

Let the tube lights of bajaj be x

So, tube light of Philips = x + 40

And, tube light of syska = x – 20

And according to Caselet

⇒ x – 20 + x + 40 + x + 120 = 500

⇒ 3x + 140 = 500

⇒ x = 120

So, the tube lights of Bajaj = 120

Tube light of Philips = 160

Tube light of syska = 100

Bulbs of Havels = 250 – (80 + 40 + 80)

= 50

 BulbsTube lights
Syska80100
Philips40160
Bajaj80120
Havels50120

According to question,

Total items of Havels in the shop = 50 + 120 = 170

Total items of Philips in the shop = 40 + 160 = 200

⇒ Required ratio = 170 : 200

⇒ 17 : 20∴ The ratio between total number of Havells items in the shop to the total number of Philips items in the shop is 17 : 20

Number of tube lights of Havells is 150% of the bulbs of Syska which is equal to the bulbs of Bajaj available in the shop which is 80 in number. Number of bulbs of Philips is half of the number of bulbs of Syska. Number of tube lights of Philips is 40 more than the number of tube lights of Bajaj and number of tube lights of Syska is 20 less than the number of tube lights of Bajaj.

Question:

The number of Bulbs of Philips is what percent of number of tube light of Bajaj?

A. 66.67%

B. 12.5%

C. 56%

D. 45%

E. 33.33%

Solution

According to Caselet tube light is 100% more than the total bulbs in the shop

So, total bulbs in the shops = 500 / 200 × 100 = 250

Bulbs of syska = bulb of bajaj = 80

Tube lights of Havels = 150 / 100 × 80 = 120

Bulbs of Philips = (1 / 2) × bulbs of syska

= (1 / 2) × 80 = 40

Let the number of tube lights of bajaj be x

So, tube light of Philips = x + 40

And, tube light of syska = x – 20

And according to Caselet

⇒ x – 20 + x + 40 + x + 120 = 500

⇒ 3x + 140 = 500

⇒ x = 120

So, the tube lights of Bajaj = 120

Tube light of Philips = 160

Tube light of syska = 100

Bulbs of Havels = 250 – (80 + 40 + 80) = 50

 BulbsTube lights
Syska80100
Philips40160
Bajaj80120
Havels50120

Now, Bulb of Philips = 40

Tube light of bajaj = 120

⇒ Required percentage = (40 / 120) × 100 = 33.33%∴ The number of bulbs of Philips is 33.33% of the number of tube lights of Bajaj

A. 314

B. 320

C. 304

D. 300

E. 294

Solution

According to Caselet tube light is 100% more than the total bulbs in the shop

So, total bulbs in the shops = 500 / 200 × 100 = 250

Bulbs of syska = bulb of bajaj = 80

Tube lights of Havels = 150 / 100 × 80 = 120

Bulbs of Philips = (1 / 2) × bulbs of syska

= (1 / 2) × 80 = 40

Let the tube lights of bajaj be x

So, tube light of Philips = x + 40

And, tube light of syska = x – 20

And according to Caselet

x – 20 + x + 40 + x + 120 = 500

3x + 140 = 500

X = 120

So, the tube lights of Bajaj = 120

Tube light of Philips = 160

Tube light of syska = 100

Bulbs of Havels = 250 – (80 + 40 + 80)

= 50

D. 150%

E. 110%

Solution

Number of tube light is 100% more than the total bulbs in the shop

So, total bulbs in the shops = 500 / 200 × 100 = 250

Bulbs of syska = bulb of bajaj = 80

Tube lights of Havels = 150 / 100 × 80 = 120

Bulbs of Philips = (1 / 2) × bulbs of syska

⇒ (1 / 2) × 80 = 40

Let the tube lights of bajaj be x

So, tube light of Philips = x + 40

And, tube light of syska = x – 20

And according to Caselet

⇒ x – 20 + x + 40 + x + 120 = 500

⇒ 3x + 140 = 500

⇒ x = 120

So, the tube lights of Bajaj = 120

Tube light of Philips = 160

Tube light of syska = 100

Bulbs of Havels = 250 – (80 + 40 + 80)

= 50

 BulbsTube lights
Syska80100
Philips40160
Bajaj80120
Havels50120

⇒ Required percentage = [(120 – 50) / 50] × 100 = 140%∴ The number of Tube light of Bajaj in shop is 140% percent more than the bulbs of Havells in the shop.


42. A and B can fill a tank in 20 and 25 hours respectively. Both are opened simultaneously and after some time B is closed and the tank is filled in 16 hours. Find time for which A works alone.

A. 8

B. 9

C. 10

D. 11

E. 12

Solution

Given:-

Time for A to fill the tank = 20 hours

Time for B to fill the tank = 25 hours

Total time taken to fill the tank = 16 hours.

Concept used:-

Considering capacity of tank equal to LCM of filling and emptying pipes/leaks.

Calculation:-

Capacity of tank = LCM of (20, 25) = 100 units

Work done by A in 1 hour = 100 / 20 = 5 units.

Work done by B in 1 hour = 100 / 25 = 4 units.

Let, B worked for x hours, then,

16 × 5 + 4 × x = 100

⇒ x = 5 hours.

A works alone for 16 – 5 = 11 hours.

∴ A works alone in 11 hours.


43. The area of the  rectangle is divided equally into two squares, the perimeter of the rectangle is 36 cm. If the breadth of the rectangle is 6 cm. Find the  area of the one square.

A. 18 cm2

B. 36 cm2

C. 48 cm2

D. 24 cm2

E. None of these

54. If the speed of the 54 kmph train crosses the man standing on the platform in 23 seconds. if the same train is crossed by the speed of train B is 72 kmph running in the same direction in 80 seconds. Find the length of train B.

A. 70m

B. 45m

C. 55m

D. 65m

E. 75m

Formula used:

Distance = Speed × Time

Relative Speed (same direction) = Speed of Train B – Speed of Train A

Calculation:

Convert speed of Train A to m/s: 54 × (1000 ÷ 3600) = 15 m/s

Length of Train A = 15 × 23 = 345 meters

Relative Speed = 72 – 54 = 18 km/h = 18 × (1000 ÷ 3600) = 5 m/s

Let length of Train B = L meters

Total distance to cross = 345 + L meters

Using Distance = Speed × Time:

⇒ 345 + L = 5 × 80

⇒ 345 + L = 400

⇒ L = 400 – 345

⇒ L = 55 meters

∴ The length of Train B is 55 meters.

⇒ Interest for 1 year = Rs. 6800/4

⇒ Rs. 1700

⇒ Interest of 3 years = Rs 5100

⇒ Sum of money invested = 15,100 – 5,100

⇒ Rs 10,000

⇒ Rate of interest = (1700/10,000) × 100%

⇒ 17%

 Rate of interest is 17%

68. The average expenditure of a Shankar for the first five months is Rs. 1400 and for the next seven months is Rs. 1500. Find his monthly average income if he saves Rs. 3200 during the year.

A. Rs 1725

B. Rs 1250

C. Rs 1315

D. Rs 1435

E. None of these

Solution

Given 

Average expenditure for the first five months = Rs. 1400

Average expenditure for the next seven months = Rs. 1500

Formula Used 

Income  =  Expenditure + Savings

Calculation

We know that, Income = Expenditure + Savings

Total Expenditure = 1400 × 5 + 1500 × 7 = 7000 + 10500 = Rs. 17500

Total Savings = Rs 3200

Total Income = 17500 + 3200 = Rs. 20700

 Average income = 20700/12 = 1725

∴The monthly average income of Shankar is Rs. 1725.


69. Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers.

Quantity A: A mixture of spirit and water measure 90 liters. It contains 20% water. How much water should be added to it so that water may be 50%?

Quantity B: 45 litres

A. Quantity A > Quantity B

B. Quantity A < Quantity B

C. Quantity A ≥ Quantity B

D. Quantity A ≤ Quantity B

E. Quantity A = Quantity B or No relation.

Solution

Quantity A:

Given that, mixture of 90 litres of the spirit and water contains 20% water.

In the first mixture

Water = (20/100) × 90 = 18 litres

∴ Spirit = 90 – 18 = 72 litres

After adding some water to the mixture, water became 50% of the new mixture

∴ 72 litres of water in new mixture = 50% of new mixture

∴ Total litres of new mixture = (100/50 × 72) = 144litres

So, water to be added = 144 – 90 = 54 litres

Quantity B:

45 litres

∴ Quantity A > Quantity B


70. Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers.

Quantity A: A boat goes 8 km upstream and comes back in 6 hours. Speed of the current is 1 km/hr then find the time taken by the boat to travel the same distance in still water. 

Quantity B: 2 hours

A. Quantity A > Quantity B

B. Quantity A < Quantity B

C. Quantity A ≥ Quantity B

D. Quantity A ≤ Quantity B

E. Quantity A = Quantity B or No relation.

Solution

Quantity A:

Let the speed of boat in still water be B km/hr

According to the given statement, boat goes 8 km upstream and comes back in 6 hours and speed of the current is 1 km/hr

⇒ {8/(B + 1)} + {8/(B – 1)} = 6

⇒ 16B = 6B2 – 6

⇒ 6B2 – 18B + 2B – 6 = 0

⇒ 6B(B – 3) + 2(B – 3) = 0

⇒ (B – 3)(6B + 2) = 0

⇒ B = 3 km/hr and -2/6 km/hr

⇒ Speed of boat in still water = 3 km/hr

⇒ Time taken to cover the distance in still water = 8/3 = 2 hours 40 minutes

Quantity B:

2 hours

∴ Quantity A > Quantity B

76. Read the sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. The number of that part is the answer. If there is no error, the answer is (5). Ignore errors of punctuation, if any.

Hopefully, things would settle down for them now(A)/, but it was comforting(B)/ to know which their love(C)/ was strong enough to survive the worst. (D)/ No error. (E)

A. C

B. D

C. A

D. B

E. E

Solution

The correct answer is “C“.

Key Points

  • The error lies in part (C) of the sentence.
  • The usage of the pronoun ‘which‘ is incorrect. Instead, ‘that‘ should be used.
  • In a defining clause, we use that. In non-defining clauses, we use which.
  • The correct sentence- “Hopefully things would settle down for them now, but it was comforting to know that their love was strong enough to survive the worst.”
  • Hence, the correct answer is option 1.


Additional Information

Now you need shoes—but which ones?

Let us have a look at some examples of that and which in a sentence:

The suitcase didn’t seem that heavy at the time.

He spoke so well that everybody was pleased.

Then he looked up to find the nest from which they had fallen.


77. Read the sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. The number of that part is the answer. If there is no error, the answer is (5). Ignore errors of punctuation, if any.

I try to be an ambivert when I can, (A)/ hanging out for other people (B)/ but still relaxing by myself (C)/ when I need to (D)/. No error. (E)

A. C

B. A

C. D

D. B

E. E

Solution

The correct answer is ‘B‘.

Key Points

Hence, the correct answer is option 4.

The error lies in the usage of the preposition ‘for‘.

The correct preposition to be used here is ‘with‘.

Hanging out ‘with‘ other people and not hanging out ‘for‘ other people.

With– in the company of somebody/something; in or to the same place as somebody/something.

Example – She came to the airport with him. 

For– used to indicate purpose.

Example  I’ve waited at that station for five hours.

​The correct sentence- “I try to be an ambivert when I can, hanging out with other people but still relaxing by myself when I need to.”


78. Read the sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. The number of that part is the answer. If there is no error, the answer is (5). Ignore errors of punctuation, if any.

He was (A)/ quite preparing to (B)/ use militant rhetoric (C)/ in attacking his opponents.(D) No error. (E)

A. B

B. A

C. D

D. C

E. E

Solution

The correct answer is ‘B‘.

Key Points

Hence, the correct answer is option 1.

The error lies in part (B) of the sentence.

By the word ‘was‘ we get to know that the sentence is talking about something that has already happened.

The sentence is in past tense, and we need to use the word ‘prepared‘ instead of ‘preparing‘.

The usage of gerund (preparing) is wrong. 

One might get confused regarding the parallelism structure, ‘preparing‘ and ‘attacking‘ but that would be totally incorrect.

The correct sentence is- “He was quite prepared to use militant rhetoric in attacking his opponents.”


79. In the following question a sentence is divided into four parts. Find out which part of the sentence contains an error. If there is no error in the any part of the sentence, mark option 5 i.e. ‘No error.’ Ignore the error of punctuations, if any.

It’s discourteous to (A)/ assume that we’re so (B)/ dull that we would not (C)/ make these decisions ourselves.(D)/ No error (E)

A. A

B. B

C. C

D. D

E. No error

Solution

The correct option is option 3 i.e. C – the error lies in this part.

Key Points

  • In option 3, the usage of ‘would not’ is incorrect.
  • Instead of ‘would not‘ we will use ‘can’t.’
  • According to the rule, ‘to refer to the mental / physical abilities that are not permanent – use ‘can’t’ – NOT ‘would not.’
  • Let’s see some examples:
    • I can’t decide the next step. (Mental ability)
    • If the driver can’t move his car, he must turn on the hazard lights, call the police and place a warning triangle on the road. (Physical ability – moving car) 

Correct sentence: “It’s discourteous to assume that we’re so dull that we can’t make these decisions ourselves.

Additional Information

“We couldn’t finish all the food.”

Wouldn’t (i.e. would not) – implies that someone (or something) in particular usually does not fulfill an activity, but is certainly capable of doing so.

Couldn’t (i.e. could not) – implies that someone (or something) in particular is unable to fulfill an activity, even if s/he/it strove to do so.

Example:

I wouldn’t jump into a fire, but I am capable of doing so.

I couldn’t jump to the moon, even if I had a running start.

In statements, we use “can’t” for present tense, and “couldn’t” for past tense.

Examples: 

“I can’t help you right now.”


80. In the following question a sentence is divided into four parts. Find out which part of the sentence contains an error. If there is no error in the any part of the sentence, mark option 5 i.e. ‘No error.’ Ignore the error of punctuations, if any.

Never embark on (A)/ what comes after (B)/ without having master (C)/ what goes before.(D)/ No error (E)

A. A

B.. B

C. C

D. D

E.  No error 

Solution

The correct option is option 3 i.e. C – has an error.

Key Points

  • The given sentence has the participle ‘having’ in it.
  • Perfect participle clauses show that the action they describe was finished before the action in the main clause. The perfect participle is formed by putting the present participle having in front of the past participle.
    • Example: Having got dressed, he slowly went downstairs.
    • Example: Having finished their training, they will be fully qualified doctors. 
    • Example: Having been made redundant, she started looking for a new job.
  • Hence, V3 (mastered) should be used after the participle having.

Correct sentence : ‘Never embark on what comes after without having mastered what goes before.’ 


81. Directions: Read the passage given below and answer the questions that follow by choosing the correct/most appropriate options:

The young human child, even as the innate and adaptive immune systems start to mature, is at risk from many pathogenic viruses, bacteria, fungi, and parasites. Nevertheless, he or she has a good chance of survival in developed countries. Before there was good nutrition, hygiene, and comprehensive vaccination, there was high mortality in infants and young children. In 1900, the UK infant mortality rate was 140 per 1000, falling to 7 per 1000 by 2000. This reduction in mortality was proportionally greater in infants and children compared with other age groups. Better prevention and control of infections account for most of this fall. However, in many countries, infant mortality rates remain above 50 per 1000, giving some indication of the evolutionary pressure that must have selected a working protective immune system. Furthermore, such pressure has selected the extreme genetic polymorphism in the MHC, which through peptide presentation to T cells and NK cells is a key regulator of almost all immune responses.

The immune system gradually matures during infancy. Critical early protection against many infectious diseases previously experienced by the mother is given by the passive IgG antibody transferred from the mother transplacentally and in milk. Once that fades away, young children become more vulnerable to infections, though by then better armed with the maturing innate and adaptive immune systems. The risks are now much reduced by vaccinations, which stimulate protective immune responses in the maturing immune system. Nevertheless, children may still acquire viral, bacterial, and parasitic infections that have to be fought off and controlled by immune responses. Besides promoting recovery, such antigen stimulation results in immunological memory. Thus, over time, protection provided by the immune response increases, and young adults suffer fewer infections. This accumulation of immunological memory is an evolving feature of the adaptive immune response. The memory persists into old age but then may fade.

Besides frank infections and vaccinations, the newborn is exposed to other antigens. He or she comes from a relatively sterile environment in utero and is then rapidly _______ to multiple microbes. The first major exposure to bacteria is during passage through the birth canal, and then as soon as he/she makes oral, skin, and respiratory contact with the exterior. From then on, exposure to microorganisms is continuous. the gut and other mucosal sites (1)/ including the digestion of food (2)/ and the acquisition of vital nutrients (3)/ are essential for a healthy life (4)/ many of the bacteria that colonize (5)/. They also impact the development of the immune system.

As the child grows, the immune repertoire is also shaped by intercurrent infections and vaccinations. Pathogenic infections can be documented by symptomatic illnesses suffered by the child or adult, but for many viruses, such as influenza, an infection may be subclinical, but still sufficient to stimulate or boost immune responses. Generally, the protection offered by the immune response, both by antibodies and T cells, is very potent. Most childhood infections happen only once and then protection is lifelong.

It is remarkable that a mother can transfer sufficient antibodies to protect her infant when she was infected 20–30 years previously. The transmission of protective antibody protection from a mother to her child is hugely important, especially in environments where 15% or more infants and children die of infection. Paradoxically, a mother who avoided a dangerous childhood infection, through herd immunity, may actually put her child at risk by being unable to transfer specific protective antibodies.

Question:

What actually ​is an evolving feature of the adaptive immune response?

A. The development of the immune system.

B. Many of the bacteria that colonize the gut and other mucosal sites.

C. The accumulation of immunological memory.

D. The transmission of protective antibody protection from a mother to her child.

E. Better prevention and control of infections.

Solution

The correct answer is The accumulation of immunological memory.

Key Points

  • The second-last sentence of the second paragraph says “This accumulation of immunological memory is an evolving feature of the adaptive immune response.”
  • From the above sentence, we can say that the accumulation of immunological memory is an evolving feature of the adaptive immune response.
     

Hence, the only possible answer is option 3.

B. By continuous exposure to microorganisms.

C. When she was infected 20–30 years previously.

D. By being unable to transfer specific protective antibodies.

E. The over time, protection provided by the immune response.

Solution

The correct answer is By being unable to transfer specific protective antibodies.

Key Points

  • The last sentence of the fifth paragraph says “Paradoxically, a mother who avoided a dangerous childhood infection, through herd immunity, may actually put her child at risk by being unable to transfer specific protective antibodies.”
  • From the above sentence, we can say that a mother who avoided a dangerous childhood infection may actually put her child at risk by being unable to transfer specific protective antibodies.

Pathogenic infections can be documented by symptomatic illnesses suffered by the child or adult, but for many viruses, such as influenza, an infection may be subclinical, but still sufficient to stimulate or boost immune responses. Generally, the protection offered by the immune response, both by antibodies and T cells, is very potent. Most childhood infections happen only once and then protection is lifelong.

It is remarkable that a mother can transfer sufficient antibodies to protect her infant when she was infected 20–30 years previously. The transmission of protective antibody protection from a mother to her child is hugely important, especially in environments where 15% or more infants and children die of infection. Paradoxically, a mother who avoided a dangerous childhood infection, through herd immunity, may actually put her child at risk by being unable to transfer specific protective antibodies.

Question:

Which of the following can be inferred from the third paragraph?

A. The continuous vulnerability of humans to microorganisms.

B. The transmission of protective antibody protection.

C. An infection sufficient to stimulate or boost immune responses.

D. Vaccinations stimulate protective immune responses in the maturing immune system.

E. Better prevention and control of infections account for reduction in mortality.

Solution

The correct answer is The continuous vulnerability of humans to microorganisms.

Key Points

  • Let us explore the given paragraphs:
    • The first paragraph is talking about better prevention and control of infections account for reduction in mortality.
    • The second paragraph is talking about vaccinations that stimulate protective immune responses in the maturing immune system.
    • The third paragraph is talking about the exposure of a newborn from a sterile environment to multiple microbes.
    • The fourth paragraph is talking about an infection sufficient to stimulate or boost immune responses.
    • The fifth paragraph is talking about the transmission of protective antibody protection.
  • Therefore, from the given options, the first option can be inferred from the third paragraph.

Hence, the only possible answer is option 1.


84. Directions: Read the passage given below and answer the questions that follow by choosing the correct/most appropriate options:

The young human child, even as the innate and adaptive immune systems start to mature, is at risk from many pathogenic viruses, bacteria, fungi, and parasites. Nevertheless, he or she has a good chance of survival in developed countries. Before there was good nutrition, hygiene, and comprehensive vaccination, there was high mortality in infants and young children. In 1900, the UK infant mortality rate was 140 per 1000, falling to 7 per 1000 by 2000. This reduction in mortality was proportionally greater in infants and children compared with other age groups. Better prevention and control of infections account for most of this fall. However, in many countries, infant mortality rates remain above 50 per 1000, giving some indication of the evolutionary pressure that must have selected a working protective immune system. Furthermore, such pressure has selected the extreme genetic polymorphism in the MHC, which through peptide presentation to T cells and NK cells is a key regulator of almost all immune responses.

The immune system gradually matures during infancy. Critical early protection against many infectious diseases previously experienced by the mother is given by the passive IgG antibody transferred from the mother transplacentally and in milk. Once that fades away, young children become more vulnerable to infections, though by then better armed with the maturing innate and adaptive immune systems. The risks are now much reduced by vaccinations, which stimulate protective immune responses in the maturing immune system. Nevertheless, children may still acquire viral, bacterial, and parasitic infections that have to be fought off and controlled by immune responses. Besides promoting recovery, such antigen stimulation results in immunological memory. Thus, over time, protection provided by the immune response increases, and young adults suffer fewer infections. This accumulation of immunological memory is an evolving feature of the adaptive immune response. The memory persists into old age but then may fade.

Besides frank infections and vaccinations, the newborn is exposed to other antigens. He or she comes from a relatively sterile environment in utero and is then rapidly _______ to multiple microbes. The first major exposure to bacteria is during passage through the birth canal, and then as soon as he/she makes oral, skin, and respiratory contact with the exterior. From then on, exposure to microorganisms is continuous. the gut and other mucosal sites (1)/ including the digestion of food (2)/ and the acquisition of vital nutrients (3)/ are essential for a healthy life (4)/ many of the bacteria that colonize (5)/.

Question:

Rearrange the jumbled sentence to make a grammatically correct and meaningful sentence.

the gut and other mucosal sites (1)/ including the digestion of food (2)/ and the acquisition of vital nutrients (3)/ are essential for a healthy life (4)/ many of the bacteria that colonize (5)/.

A. 15342

B. 24135

C. 31254

D. 35421

E. 51423

Solution

The correct answer is 51423.

Key Points

  • The correct sequence or order of the segments after rearrangement is 5-1-4-2-3.
    • Sentence ‘5‘ is independent of any other sentence as it introduces the topic of ”Many of the bacteria that colonize. Hence, ‘5‘ is the first part.
    • Sentence will come after as it is giving information about what actually many of the bacteria colonize i.e. the gut and other mucosal sites.
    • Sentence will come after as it is saying that many of the bacteria that colonize the gut and other mucosal sites are essential for a healthy life.
    • Sentence will come after as it is further giving information what is included in a healthy life i.e. the digestion of food.
    • The sentence ‘3‘ is the last or concluding part as it is giving information about what is further included in a healthy life i.e. the acquisition of vital nutrients.
       

Hence, the correct answer is option 5.

Correct sentence: Many of the bacteria that colonize the gut and other mucosal sites are essential for a healthy life, including the digestion of food and the acquisition of vital nutrients.

By who was the Mahabharata written?

A. By who is

B. By which was

C. By whom was

D. No improvement

E. None of the above

Solution

The correct answer is option 3) i.e. By whom was.

Explanation

  • The given sentence starts with the preposition ‘By’ and the relative pronoun ‘who’.
  • Also, we can see that the given sentence is an interrogative sentence as (?) is used.
  • If preposition is used at the start of the sentence, a relative pronoun or interrogative pronoun is used with the preposition.
  • Preposition+whom‘ is correct but not ‘preposition+who‘. ‘Whom’ should be used to refer to the object of a verb or preposition.
  • Hence, the correct sentence is “By whom was the Mahabharata written“?

    Important Point
          ​
  • An interrogative pronoun is a pronoun which is used to make asking questions easy. There are just five interrogative pronouns. Each one is used to ask a very specific question or indirect question. Some, such as “who” and “whom,” refer only to people. Others can be used to refer to objects or people.

    Mistake Point

If a preposition is used at the end of the sentence, ‘who‘ comes at the starting of the sentence.
For example, “Who was the Mahabharata written by?

Choose the correct alternative and click the button corresponding to it. In case no improvement is needed, click the option corresponding to “No improvement.”

The French were the first to use camouflage during World War I.

A. A French were

B. A French was

C. An French were

D. An French was

E. No improvement

Solution

 The correct alternative is option 5 i.e. ‘no improvement.’

Explanation

  • In the above sentence, the article in consideration is ‘the.’
  • The’ is used with the names of nationalities, sects and communities.
  • Herethe sentence refers to ‘French people’ as ‘the French.’ Hence, there is no need for improvement.
  • An example for the same is: The Indians love spices in their food.

    Short Trick

Also, options beginning with ‘an’ can be eliminated, as the article ‘an’ is used before words that begin with a vowel sound(a, e, i, o, u).

Additionally, one can also eliminate options containing the singular verb ‘was’ since ‘The French’ is a plural category, referring to the entire community.


95. A sentence/a part of the sentence is underlined. Five alternatives are given to the underlined part which will improve the meaning of the sentence. Choose the correct alternative. In case no improvement is needed, click the option corresponding to “No improvement.”

often have to attend yoga classes.

A. Have to often

B. Had often

C. Have not often

D. Had often not

E. No improvement

Solution

The correct alternative is option 5 i.e. ‘no improvement.’

 Explanation

  • As one of the rules for placement of adverbs, they are to be placed before auxiliaries like ‘have to’ and ‘used to.’
  • In this sentence, the auxiliary word ‘have to’ has been used. Here, the adverb is ‘often’ (adverb of frequency) and precedes ‘have not’ as per the above-mentioned rule.
  • Therefore, option 5 is correct and doesn’t require improvement.
  • An example of the same is: I never used to visit religious places.

Mistake Point​

Although the other options may seem correct, they are also grammatically flawed. Option 1 does not follow the rule of the adverb placement and hence cannot be the right answer.
