**Answers:**

**Answer c**

Both the trains meet at x hours after 7 am,

Distance covered by A in x hours = 20x km

Distance covered by B in (x-1) hours = 25(x-1) km

20x + 25(x-1) = 110

20x + 25x -25 =110

45x = 135

X = 135/45 = 3

1^{st} train meets second train after 3 hours = > 3 +7 = 10 am

**Answer d**

Let cost price be x,

Profit = 1200 = Sp – Cp

[X*(1/3)*(109/100) + x*(2/3)*(97/100)] – x = 1200109x +194x -300x = 360000

3x = 360000

X = 120000

**Answer b**

Total mixture = 45 litres

Milk: water = 2: 1

3’s = 45

1’s = 15

Milk = 30 lit, Water = 15 lit

30/(15+x) = 60/40

30/(15+x) = 3/2

20 = 15+x

X = 5 litres

So 5 litres of water should be added

**Answer a**

Investment ratio = > 3:5:7

Profit ratio = > 2:5:8

Period = > (2/3): (5/5): (8/7)

= > 70: 105: 120

= > 14: 21: 24

**Answer c**

5 years hence, Rahul and Ravi’s age ratio will be 3: 4 (3x, 4x)

Present age of Rahul and Ravi = 3x-5, 4x-5

The present age of Rahul is equal to Ravi’s age 10 years ago

3x-5 = 4x-15

X = 10

Present age of Rahul and Ravi = 3x-5, 4x-5 = 25, 35

**Directions (Q. 6-10): **

**Answer b**

The difference is, 6^{2}-6, 8^{2}-8, 10^{2}-10, 12^{2}-12, 14^{2} -14…

The answer is, 495

**Answer d**

The pattern is, ÷ 8, ÷ 6, ÷ 4, ÷ 2

The answer is, 8

**Answer c**

The pattern is, *3-6, *4-8, *5-10, *6-12…

The answer is, 18048

**Answer b**

The difference is, 3, 3^{2}, 3^{3}, 3^{4}…

The answer is, 133

**Answer d**

The pattern is, *2+1^{2}, *3+3^{2}, *4+5^{2}, *5+7^{2}, *6+9^{2}…

The answer is, 3654

**Directions (Q. 11–15): **

**Answer b**

(135 ×135× 39)/15 ÷ x = 60 × 52

X = (135 ×135× 39)/(15×60 × 52)

X = 15.1875

**Answer c**

1272/x = 1382 – 956 – 214

X = 1272/ 212

X = 6

**Answer d**

(444/12) × 28 – 612 = x

X= 1036 – 612

X= 424

**Answer c**

3/8 × 4/9 × 1575 + (√?) – 32% of 786 = 66.98

1/2 × 525 + (√?) – (32/100) × 786 = 66.98

262.5 + (√?)– 251.52 = 66.98

262.5 – 251.52 + (√?) = 66.98

(√?) = 56

? = (56)^{2} = 3136

**Answer d**

∛97336 +√6889 ÷ 2^{?}– 3/4 of 65 + 5^{2} = 43

46 + 83/2^{x} – 48.75 + 25 = 43

83/20.75 = 2^{x}

4 = 2^{x} = > 2^{2} = 2^{x}

x = 2

** **

**Directions (Q. 16 – 20): **

**Answer a**

Females in department B = (40/100)*290 = 116

In department C = (35/100)*360 = 126

Required % = (126-116)/126 * 100 ≈ 8%

**Answer c**

3/5 * (75/100) * 540 = 243

**Answer a**

Females in A = (20/100)*450 = 90

Males in B who come are unmarried = (1/3) * (60/100)*290 = 58

Difference = 90 – 58 = 32

**Answer a**

D + E = (75/100)*540 + (80/100)*250 = 405 + 200 = 605

**Answer b**

Unmarried males in department C = (4/9) * (65/100)*360 = 104

Married Males in department B = (2/3) * (60/100)*290 = 116

104: 116 = 26: 29
