6. DIRECTIONS: In the following question assuming the given statements to be true, find which of the conclusion among the given conclusions is/are definitely true and then give your answers accordingly.

Statements: U ≥ R, H < L, P ≤ N, H = K, R = P

Conclusions:

 I. U > P 

II. U = P

A. Only conclusion I follows

B. Only conclusion II follows

C. Either conclusion I or II follows

D. Neither conclusion I nor II follows 

E. Both conclusion I and II follow

Solution

Given Statements : U ≥ R, H < L, P ≤ N, H = K, R = P

On combining : U ≥ R = P ≤ N , K = H < L

 I. U > P → False ( As U ≥ R = P, it is a possibility but not definitely true, Hence U > P is False )

II. U = P → False  (As U ≥ R = P, it is a possibility but not definitely true, Hence U = P is False )

Both the conclusion are false and greater than equal to make the complementary pair so it will be the case of either or.

Hence, Either I or II follows.


7. Directions: In the following question assuming the given statements to be True, find which of the conclusion among given conclusions is/are definitely true and then give your answers accordingly.

Statements :  B > Q > I,  K < T = P < Q,  B < N < R

Conclusions :

I. K < R

II. I > K

A. Both I and II Follow

B. Only II Follows

C. Either I or II Follows

D. Only I Follows

E. Neither I nor II Follows

Solution

Given statements:  B > Q > I,  K < T = P < Q,  B < N < R

On combining: K < T = P < Q < B < N < R ; K < T = P < Q > I

Conclusions:

I.K < R → True (As K < T = P < Q < B < N < R → K < R)

II. I > K → False (K < T = P < Q > I → thus clear relation between I and K cannot be determined)

Hence, Only conclusion I Follows.


8. Direction: In the following question assuming the given statements to be true, find which of the conclusion among given conclusions is/are definitely true and then give your answers accordingly.

Statements: E ≥ A = W; B < X; E ≤ S ≤ T < B

Conclusions:

I. T > A 

II. T ≤ A

A. Only I follow

B. Only II follow

C. Both I and II follows

D. Either I or II follows

E. Neither I nor II follows

Solution

Given Statements: E ≥ A = W; B < X; E ≤ S ≤ T < B

On Combining: X > B > T ≥ S ≥ E ≥ A = W

Conclusions:

I. T > A → False (As T ≥ S ≥ E ≥ A → T ≥ A. So, it is false)

II. T ≤ A  → False (As T ≥ S ≥ E ≥ A → T ≥ A. So, it is false)

Hence, neither I nor II follows.

Confusion Points

Here the given condition between T and A is,

T ≥ S ≥ E ≥ A → T ≥ A.

It means that T is greater than equal to A this will be true for all conditions.

In the given conclusion three sign present between the T and A as <, >, =, but the three sign concept will be applicable when there is no relationship defined between the two elements in the given statement but here T ≥ A it is a definite statement between them so except that all will be considered as false.

Hence, Neither I nor II follows.

14. Directions: Study the information given below carefully and answer the questions that follow.

Arun starts from point P and goes 8m North to reach point Q and then takes a left turn and goes 8m to reach point R. From R he takes a right turn and travels 10m to point S and after reaching there he takes a left turn and walks 12m to reach point T. From point T he takes a left turn and walks 18m to finally reach point V.

Question:

What is the shortest distance between V and Q?

A. 164

B. √164m

C. 464

D. √535m

E. √464m

Solution

We have drawn the figure according to the information given in the question,

By using the Pythagorean Theorem,

VQ= PQ2 + UP2

VQ2 = 82 + 202

VQ = √464

Then for how many months B stayed in the business?

A. 6 months

B. 8 months

C. 10 months

D. 12 months

E. 4 months

Solution

Given:

A, B, and C started a business with an investment ratio of 10 : 12 : 15

C stayed for 1 year in the business, but the other two left after some months

The profit is divided in the ratio of 5 : 8 : 15

Calculation:

Let, A stayed in the business after p months

B stayed in the business after q months

According to the question,

⇒ (10 × p) : (12 × q) : (15 × 12) = 5 : 8 : 15

So, we can write that

⇒ (12 × q) : (15 × 12) = 8 : 15

⇒ q = 8

∴ B stayed in the business after 8 months

A. 35 litres

B. 25 litres

C. 40 litres

D. 45 litres

E. 55 litres

Solution

Solution:
Milk in the mixture initially = 7a
Water in the mixture initially = 5a
Honey in the mixture initially = 4a
If 12 litres of milk and 9 litres of honey is added, then the ratio of milk and honey to the total mixture is 8: 11
(7a + 12 + 4a + 9)/(7a + 12 + 4a + 9 + 5a) = 8/11
(11a + 21)/ (16a + 21) = 8/11
(121a + 231) = (128a + 168)
7a = 63
a = 9    
Initial quantity of water in the mixture = 9 ×  5 = 45

A. 5% decrease

B. 5% increase

C. 5.26% increase

D. 5.26% decrease

E. None of these

Solution

Given:

Kamal scored an average of 80 in 5 subjects

Marks of History & Geography is wrongly entered as 85 and 90 respectively

Actual marks in History & Geography are 75 and 80 respectively

Concept Used:

Average (A) = S/N

Where S =  sum of observations, and N = number of observations

Calculation:

The total marks in 5 subjects = 80 × 5 = 400

Total marks of wrong input = 85 + 90 = 175

Actual total marks = 75 + 80 = 155

Net error marks = 175 – 155 = 20

Now, total marks of Kamal = 400 – 20 = 380

So, the average marks of Kamal = 380/5 = 76

His average marks decreased by = 100 × (80 – 76)/80 = 5%

∴ The correct answer is option 1

63. A train crosses a 500 m long platform in 2 minutes at the speed of 72 km/hr, then find in how much time it crosses another train of same length travelling at a speed of 108 km/hr in opposite direction.

A. 76 seconds

B. 84 seconds

C. 96 seconds

D. 120 seconds

E. None of these 

Solution

Given:

The speed of train = 72 km/hr

The length of platform = 500 m

The speed of another train = 108 km/hr

Formula used:

Distance = speed × time

Concept used:

To convert speed from km/hr to m/s the multiply with 5/18 

Relative speed concept,

Speed of both trains will add when the train moves in the opposite direction

Speed of both the train will subtract when the train moves in the same direction

Calculation:

Let the length of train be l 

Now, Distance = speed × time 

⇒ l + 500 = 72 × 5/18 × 120

⇒ l = 1900 m

The total length of both the train = 2 × 1900 = 3800 m

Both trains moving in the opposite direction so speed = (20 + 30) = 50 m/s

Time = 3800/50 = 76 second

∴ The time taken to cross another train is 76 seconds

A. Rs. 60000

B. Rs. 75000

C. Rs. 65000

D. Rs. 70000

E. Rs. 80000

Solution

Given:

Ram spends 20% of his monthly income on Rent.

Out of the remaining, he spends 10% on his children’s education, 30% on food, and 12% on the bills

He is left with Rs. 28800 after all these expenditures

Calculation:

Let, Ram’s monthly income = 100a

After paying rent his remaining amount = 100a × (100 – 20)/100 = 80a

On this remaining amount, total expenditure = (10 + 30 + 12) = 52%

So, his saving = 80a × (100 – 52)% = 80a × 48/100

According to the question,

⇒ 80a × 48/100 = 28800

⇒ a = 750

Ram’s income = 100 × 750 = Rs. 75000

∴ The correct answer is option 2


71. Raj has invested Rs 12,000 at some rate of simple interest for 4 years and received Rs. 14,160. What will be the simple interest received by him after 4 years, if he increases the principal amount by Rs. 1,800 and the rate of interest by 4% points per annum?

A. Rs. 4,662

B. Rs. 4,992

C. Rs. 4,962

D. Rs. 4,692

E. Rs. 4,690

Solution

Given:

Initial principal = Rs. 12,000

Initial time = 4 years

and Amount received = Rs. 14,160

Formula used:

(1) S.I = (P × R × T)/100

where, S.I = Simple Interest,

P = Principal,

R = Rate of Interest

and T = Time

(2) Amount = Principal + Interest

Calculation:

Let the rate of interest be R%.

Then,

Amount = Principal + S.I

⇒ S.I = Rs. 14,160 – Rs. 12,000

⇒ (P × R × T)/100 = Rs. 2,160

⇒ (Rs. 12,000 × R × 4)/100 = Rs. 2,160

⇒ R = 4.5%

New rate of interest = (R + 4)%

⇒ (4.5 + 4)%

⇒ 8.5%

and New principal amount = Rs. 12,000 + Rs. 1,800

⇒ Rs. 13,800

Now, S.I = (P × R × T)/100

⇒ (Rs. 13,800 × 8.5 × 4)/100

⇒ Rs. 4,692

∴ The simple interest received by him is Rs. 4,692.


72. C can complete 4/7 of a work in 14 days. C and D together complete 2/7 of the same work in 4 2/3 days. Find the time taken by D to complete the entire work alone.

A. 28 days

B. 32 days

C. 49 days

D. 35 days

E. 23 days

Solution

C can complete 4/7 of the work in 14 days.

Work done by C in 1 day = (4/7) / 14 = 4/98 = 2/49

C and D together complete 2/7 of the work in 4 2/3 days (14/3) days:

Work done by C and D in 1 day = (2/7) / (14/3) = 2/7 × 3/14 = 6/98 = 3/49

D’s 1-day work = 3/49 − 2/49 = 1/49

If D does 1/49 of the work in 1 day, the time taken to complete the entire work is:

Time taken by D = 1 / (1/49) = 49 days.

Thus, D will take 49 days to complete the work alone.


73. If the speed of the stream is 3 kmph. The distance between the two points A and B is 45 km. Total time taken by the boat to cover both upstream and downstream for a distance A and B  is 8 hours. Find the speed of the boat in still water.

A. 13 kmph

B. 10 kmph

C. 12 kmph

D. 9 kmph

E. 15 kmph

Solution

Solution:

Speed of the boat in still water = a

Speed of the stream = 3kmph

Total time taken by the boat to cover upstream and downstream is 8 hours

45/(a + 3) + 45/ (a – 3) = 8

45 ×  (a – 3) + 45 ×  (a + 3) = 8 ×  (a – 3) (a + 3)

(45a – 135) + 45a + 135 = 8 ×  (a2 + 3a – 3a – 9)

90a = 8 ×  (a2 – 9)

90a = 8a2 – 72 

8a2 – 90a – 72 = 0

a = 12, a = -3/4

Speed cannot be negative 

Speed of the boat in still water = 12 kmph

Hence, option(3) is correct.

Alternate Method

Given:

Total players = 4000

Ratio of male and female players = 11 ∶ 9

Total number of players in cricket = 40% of the total players

Male players in football = 25% of total male players

Female players in football = (1/2) of the players in cricket

The ratio of male and female players in hockey = 4 ∶ 3

Calculation:

Let the male and female players be 11x and 9x respectively

Now,

11x + 9x = 4000

⇒ 20x = 4000

⇒ x = 200

Number of male players = 11 × 200

⇒ 2200

Total number of Players in cricket = 40% of 4000

⇒ (40/100) × 4000

⇒ 40 × 40

Now,

Total number of Players in hockey = 4000 – (Total number of Players in cricket + Total number of players in football)

⇒ 4000 – (1600 + 1350)

⇒ 4000 – 2950

⇒ 1050

Now,

Let the male and female players in hockey be 4x and 3x respectively

Now,

4x + 3x = 1050

⇒ 7x = 1050

⇒ x = 1050/7

⇒ x = 150

Now,

Number of female players in hockey = 3x

⇒ 3 × 150

⇒ 450

Now,

Required percentage = [(550 – 450)/450] × 100

⇒ (100/450) × 100

79. By selling one of his briefcase, a shopkeeper earns 30% profit, by offering a discount of 10%. If the difference between the marked price and the cost price is Rs. 600, then find the selling price of the briefcase.

A. Rs. 1350

B. Rs. 1950

C. Rs. 1755

D. Rs. 1955

E. None of these

Solution

Given:

A shopkeeper earns 30% profit, by offering a discount of 10%

The difference between the marked price and the cost price is Rs. 600

Concept Used:

CP/MP = (100 – D)/(100 + P)

Selling price (SP) = MP × (100 – D)/100

Where, CP = cost price, MP = marked price, D = discount % and P = profit %

Calculation:

CP/MP = (100 – 10)/(100 + 30) = 9/13

Let, CP = 9a, and MP = 13a

According to the question,

⇒ 13a – 9a = 600

⇒ a = 600/4 = 150

So, the MP of the article =  150 × 13 = Rs. 1950

The SP of the article = 1950 × (100 – 10)/100 = Rs. 1755

∴ The correct answer is option 3


80. The width of a rectangular garden is 1.5 times the radius of a circular pond, and the length of the garden is 20 meters. If the area of the pond is 2464 m2, find the perimeter of the garden.

A. 148

B. 136

C. 124

D. 168

E. 218

Solution

Formula Used:

The area of a circle is given by the formula:

Area = πr2

Calculation:

Area of the pond = 2464 m2 and taking π = 22/7

2464 = 22/7 r2

2464 × 7 = 22r2

17248 = 22r2

r= 17248 / 22 = 784

r = 28 m

The width of the garden is 1.5 × the radius of the pond:

Width = 1.5 × 28 = 42 m

The perimeter of a rectangle is given by the formula:

Perimeter = 2 × (Length + Width)

Substitute the values of length and width:

Perimeter = 2 × (20 + 42) = 2 × 62 = 124 m

Thus, the correct answer is 124 m
