**Answers :**

**Directions (1-10) :**

**1) Answer: D**

(5x + 30) /(3x + 20) = 8/5

24x + 160 = 25x + 150

x = 10

Quantity of the milk = 5 * 10 = 50 liters

**2) Answer: C**

M/T = 3/2

B + R = 66 – 16 = 50

R/S = 2/5

(B + 10)/(S + 10) = 2/3

2S + 20 = 3B + 30

2S – 3B = 10 ———(1)

T – 10 = B

B + 2S/5 = 50

5B + 2S = 250 ——-(2)

(2) – (1)

8B = 240

B = 30

T = 30 + 10 = 40

B + R = 50

R = 50 – 30 = 20

2S/5 = 20

S = 50

M = 3/2 * 40 = 60

Required ratio = (60 + 50):(30 + 40 + 20)/3

= 110:30

=11:3

**3) Answer: D**

CP of laptop = x

CP of mobile = x/2

SP of mobile = 9000

SP of laptop = 9000 + 14000 = 23000

We cannot find the answer.

**4) Answer: C**

C = 48 * 100/80 = 60 days

C done the work in 4 days = 4/60 = 1/15

A + B + C together done the work = 2/5

Remaining work = 1 – 1/15 – 2/5 = 8/15

A + B together completes 8/15 of the work in 16 days

A + B complete the whole work = 16/8 * 15 = 30 days

A + B = 1/30

1/2x + 1/x = 1/30

(1 + 2)/2x = 1/30

1/x = 1/45

x = 45 days

B complete the half of the work = 45/2 = 22.5 days

**5) Answer: B**

A + E = 1/30

B + C = 100/75 * 30 = 40

C + D = 12/11 * 44 = 48

A + B + E = 1/20

B = 1/20 – 1/30 = 1/60

B alone complete 75% of the work = 3/4 * 60 = 45 days

C = 1/40 – 1/60 = 1/120

D = 1/48 – 1/120 = 72/120 * 48 = 1/80

B + D = 1/60 + 1/80 = 7/240

B + D = 240/7 days

**6) Answer: D**

Length of train A = 3x

Length of train B = x

Speed of train A = 60 kmph

Speed of train B = 120 kmph

4x = (60 + 120) * 5/18 * 12

4x = 180 * 5/18 * 12

4x = 600

x = 150 m

Length of train A = 3 * 150 = 450

450 + length of the platform = 60 * 5/18 * 39

450 + length of the platform = 650

Length of the platform = 200

Time taken by train B crosses a pole = (150/120 * 5/18) = 4.5 seconds

**7) Answer: C**

A = 100/75 * 9 = 12 hours

B = 2/1 * 9 = 18 hours

C = 100/45 * 9 = 20 hours

LCM of (12, 18 and 20) = 360

Pipe A fill tank in one hour = 30 units

Pipe B fill tank in one hour = 20 units

Pipe C fill tank in one hour = 18 units

A and B together can fill the tank in one hour = 30 + 20 = 50 units

A and C together can fill the tank in one hour = 30 + 18 = 48 units

First two hours total work completed in = 50 + 48 = 98 units

First 6 hours the total work completed in = 98 * 3 = 294

After 7 hours = 294 + 50 = 344

Remaining work done by A and C together in= 16/48 = 1/3 hours

Total time = 7 (1/3) hours

**8) Answer: A**

Perimeter of the rhombus = 4a

Side of the rhombus = 72 cm

Perimeter of the rhombus = 72 * 4 = 288

Area of the rectangle = l * b

2x * x = 288

x = 12 cm

Length of the rectangle = 12 * 2 = 24 cm

Breadth of the rectangle = 12 * 1 = 12 cm

Perimeter of the rectangle = 2 (24 + 12) = 72 cm

Perimeter of the square = 1/4 * 288 = 72 cm

Side of the square = 72/4 = 18 cm

Area of the square = 18 * 18 = 324

Difference = 324 – 72 = 252 cm

**9) Answer: D**

Volume of the cone = 1/3 * 22/7 * r * r * h

308 = 1/3 * 22/7 * r * r * 6

Radius of the cone = 7 cm

Radius of the sphere = 2/1 * 7 = 14 cm

Radius of the cylinder = ¼ * 14 = 3.5 cm

TSA of the cylinder = 2 * 22/7 * r * (h + r)

330 = 2 * 22/7 * 3.5 * (3.5 + h)

Height of the cylinder = 11.5 cm

Volume of the cylinder = 22/7 * r * r * h

= 22/7 * 3.5 * 3.5 * 11.5 = 442.75 cm^{3}

**10) Answer: D**

Red balls = 2/6 * 30 = 10

Yellow balls = 3/6 * 30 = 15

Blue balls = 1/6 * 30 = 5

Red balls from A = 20/100 * 10 = 2

Yellow balls from A = 40/100 * 15 = 6

Blue balls from A = 20/100 * 5 = 1

Red balls from B = 10 – 2 = 8

Yellow balls from B = 15 – 6 = 9

Blue balls from B = 5 – 1 = 4

2 Yellow balls drawn from A = 6C_{2}/9C_{2} = 5/12

Three red balls drawn from B = 8C_{3}/21C_{3} = 4/95

Difference = 5/12 – 4/95 = 427/1140
