- They are simple or lower plants.
- Archegonium is absent in thallophyta.
- Thallophtes are an abandoned division of kingdom Plantae which includes fungi, algae, lichens, and some kinds of bacteria, bryophytes, and slime molds.
Gymnosperms are also known as acrogymnosperms.
- It is a group of seed-producing plants.
- It includes conifers, cycads, ginkgo, and gnetophytes.
- The word gymnosperms in greek means naked seeds because they do not have an outer covering or shell around their seeds.
- They do not produce flowers i.e they are non-flowering plants and neither do they produce fruits. Its pollination is done by the wind (Anemophilous).
Angiosperms are also known as Angiospermae or Magnoliophyta.
- They are flowering and seed-producing plants.
- It consists of 64 orders, 416 families, approximately 13,000 known genera, and 3,00,000 known species.
- Their seeds develop in the ovaries of flowers and are surrounded by a protective fruit.
- Examples of angiosperms are fruits, vegetables, grains, and flowers.
- Angiosperms are classified as Monocotyledons (monocots) and Dicotyledons (dicots) where monocots are flowering plants whose seeds contain only one embryonic leaf or cotyledon and dicots are flowering plants whose seeds contain two embryonic leaves or cotyledons.
Pteridophytes are known as the Vascular cryptogams because they are the first non-seeded plants to have a vascular system present.
- They are also called vascular crypto games.
- They are used for medicinal purposes.
- They are not completely differentiated into root, stem, and leaves.

7 : 342 :: 9 : 728 :: ? : 2196

A. 11

B. 13

C. 5

D. 9

Solutions

The pattern followed here is,

Let (M : N)

Step 1 → M³ = A (A any number)

Step 2 → A – 1= N

Now follow the steps:

7 : 342

Step 1 → 7³ = 343

Step 2 → 343 – 1 = 342

And,

9 : 728

Step 1 → 9³ = 729

Step 2 → 729 – 1 = 728

Similarly,

? : 2196

Step 1 → 13³ = 2197

Step 2 → 2197 – 1 = 2196

Hence, ‘13 : 2196’ is correct answer.

A. 25

B. 30

C. 35

D. 20

Solutions

Given:

Total amount = Rs. 9000

Calculation:

According to the question,

⇒ 9000a = (9000 – 160a)(a + 20)

⇒ 9000a = 9000a + 180000 – 160a² – 3200a

⇒ a² + 20a – 1125 = 0

⇒ a² + 45a – 25a – 1125 = 0

⇒ a(a + 45) – 25(a + 45) = 0

⇒ (a – 25)(a + 45) = 0

⇒ a = 25 or a = -45

(- 45 Neglected as the number of people can never be negative)

43. If (a + b) : (b + c) : (c + a) is 6 : 7 : 8 and also a + b + c = 14, then what is the value of c?

A. 8

B. 10

C. 6

D. 12

Solutions

Given:

(a + b) : (b + c) : (c + a) = 6 : 7 : 8

a + b + c = 14

Concept used:

If (a + b) : (b + c) : (c + a) is x : y : z

(a + b + c) = (x + y + z)/2

Calculation:

Let (a + b) : (b + c) : (c + a) be 6x : 7x : 8x

a + b + b + c + c + a = 6x + 7x + 8x

2(a + b + c) = 21x

(a + b + c) = 21x/2

⇒ 21x/2 = 14

⇒ x = 28/21

⇒ 4/3

(a + b) = 6 × 4/3 = 8

So c = 14 – 8

⇒ 6

∴ The value of c is 6

Speed = Distance/time

Calculation:

Distance cover = 8 × 3/2 = 12 km

Now at the time of return, he will cover 11 km as given in the question

He has taken a rest for 30 minutes

So he will cover 11 km in 1 hour

So his new speed = 11 km/h

Speed increased = 3 km/h

% change = 3/8 × 100

⇒ 37.5%

∴ The required increase in speed is 37.5%

50. A shopkeeper purchased a machine for Rs.70,000 and spent Rs.5,000 as overhead expenditure. Had he purchased the machine at 15% less, he would have earned a profit of 15%. What is the selling price of the machine?

A. Rs.74,000

B. Rs.75,000

C. Rs.74,175

D. Rs.78,175

Solutions

Given:

Price at which the machine was purchased = Rs.70000

Overhead expenditure = Rs.5000

Formulas used:

Profit or Loss is calculated on the Cost Price of the machine, which is 100% of itself.

Selling Price = Cost Price + Profit

Selling Price = Cost Price × (100 + Profit)%

Calculation:

Total cost of the machine = Purchasing Price + Overhead Expenses

⇒ 70000 + 5000 = Rs.75000

As per the question,

Cost of machine at 15% less = 70000 × (100 – 15)% + 5000

⇒ Rs.64500

Selling Price = 64500 × (100 + 15)/100

⇒ Rs.74175

∴ The selling price of the machine is Rs.74175.

51. A solid metallic cylinder of base radius 3 cm and height 5 cm is melted to form cones each of height 1 cm and base radius 1 mm. How many cones were formed?

A. 19,500 cones

B. 10,500 cones

C. 13,500 cones

D. 12,500 cones

Solutions

Given:

Radius of metallic cylinder = 3 cm

Height of metallic cylinder = 5 cm

Height of cone to be formed = 1 cm

Radius of cone to be formed = 1 mm or 0.1 cm

Formulas used:

Volume of cylinder = πR²H

Volume of cone = 1/3 × πr²h

Calculation:

Radius and height of the cylinder is R = 3 cm, H = 5 cm respectively.

Radius and height of the cone is r = 0.1 cm, h = 1 cm respectively.

As per the question;

Volume of metallic cylinder = No of cones × Volume of a cone

⇒ π × 3 × 3 × 5 = No of cones × 1/3 × π × 0.1 × 0.1 × 1

⇒ No of cones = (3 × 3 × 5 × 3)/(0.1 × 0.1)

⇒ No of cones = 13500

∴ The number of cones formed is 13500.

Mistake Points

1 cm = 10 mm

0.1 cm = 1 mm

52. If 1/5 of a number multiplied by 2/3 of the same number gives 480, then the number is:

A. 80

B. 70

C. 60

D. 100

Solutions

Calculation:

Let the number be = a

So, 1/5 × a × 2/3 × a = 480

⇒ 2a²/15 = 480

⇒ a² = 2⁴ × 3² × 5²

⇒ a = √24 × 32 × 52

⇒ a = 4 × 3 × 5 = 60

∴ The required number is 60.

Alternate Method By Hit and Trial Method

We will check the condition as, 1/5 × a × 2/3 × a = 480

Option 1: For a = 80, 1/5 × 80 × 80 × 2/3 ≠ 480

Option 2: For a = 70, 1/5 × 70 × 70 × 2/3 ≠ 480

Option 3: For a = 60, 1/5 × 60 × 60 × 2/3 = 480

Option 4: For a = 100, 1/5 × 100 × 100 × 2/3 ≠ 480

53. In a class 82% students passed and 2% students were placed in the reappear category. The number of students who failed was 592. What was the total number of students in the class?

A. 2700

B. 3600

C. 2000

D. 3700

Solutions

Given:

Percentage of students passed = 82%

Percentage of students placed in reappear category = 2%

Number of students failed = 592

Calculation:

Let the total number of students be 100%

Percentage of students failed = 100% – Passed Percent – Reappear Category Percent

⇒ 100% – 82% – 2%

⇒ 16%

∵ 16% = 592

⇒ 100% = 592 × 100%/16%

⇒ 100% = 3700

∴ Total number of students in the class are 3700.

A. 60

B. 100

C. 110

D. 98

Solutions

Given:

Number of question attempted = 120

Marks received by Ambika = 90

Marks awarded for correct answer = 1

Marks deducted for wrong answer = 0.5

Calculation:

Let the number of correct answer be = a

⇒ Number of wrong answers = 120 – a

Marks for ‘a’ right answers = a × 1 = a

Marks deducted for (120 – a) wrong answers = (120 – a) × 0.5 = 60 – 0.5a

As per the question;

Total marks scored = Marks received for right answers – Marks deducted for wrong answers

⇒ 90 = a – (60 – 0.5a)

⇒ 1.5a = 150

⇒ a = 100

∴ The number of correct answers is 100.

A. 8:30:00 hours

B. 8:27:12 hours

C. 8:40:00 hours

D. 8:25:00 hours

Solutions

Given:

3 traffic signals change after every 48, 72 and 108 respectively.

Time when 3 lights started changing simultaneously = 8:20

Concept Used:

Lowest Common Multiple

Calculation:

The time of changing the 3 traffic lights simultaneously will be the LCM of 48, 72, and 108 as the first common multiple of the numbers.

By Prime Factorisation we will take LCM of 48, 72 and 108 seconds.

48 = 2⁴ × 3

72 = 2³ × 3²

108 = 2² × 3³

LCM ( 48, 72, 108) = 2⁴ × 3³ = 432

Hence after 432 seconds, they will change simultancously.

⇒ 432/60 minutes

⇒ 7 minutes 12 seconds

∴ Lights will change at 8:20:00 + 7 minutes + 12 seconds = 8:27:12 hours

58. A, B and C entered into partnership. A invested 3 times as much as B and B invested 2/3 times of what C invested. At the end of the year the total profit was Rs.6,600. B’s share in the profit is:

A. Rs.2400

B. Rs.1200

C. Rs.1600

D. Rs.1800

Solutions

Given:

A’s investment = 3 times as much as B’s investment

B’s investment = 2/3 times of C’s investment

Total profit of the year = Rs.6600

Concept used:

Ratio of investment = Ratio of Profit to be shared

Calculation:

Let the sum invested by C = a

⇒ Sum invested by B = 2/3 × a

⇒ Sum invested by A = 2a/3 × 3 = 2a

Ratio of profit to be shared between A, B, and C:

A : B : C = a : 2a/3 : 2a

⇒ A : B : C = 3 : 2 : 6

B’s profit share will be = Rs.6600 × 2/11

⇒ Rs.1200

∴ B’s share in the profit for the year is Rs.1200.

A. 50%

B. 33%

C. 75%

D. 25%

Solutions

Given:

A’s height = 25% less than that of B

Calculation:

Let the height of B = 100

⇒ A’s height = 100 – 100 × 25/100

⇒ A’s height = 75

Difference between the height of B and A = 100 – 75 = 25

∴ The required percentage = 25/75 × 100

⇒ 33.33%

Shortcut Trick 25% = 25/100 = 1/4

⇒ A/B = 3/4

∴ The required percentage = (4 – 3)/3 × 100

⇒ 33.33%
