Answers :

Directions (1 – 5):

1) Answer: B

35% of 120 + 60% of 650 + 150% of 90=?

42 + 390 + 135=?

567=?

2) Answer: C

70% of 80 + 1800 ÷ 9 – 20 * 12 =?

56 + 200 – 240=?

?=16

3) Answer: D

√529 * 5 + 80% of 135 =? + 15% of 180

115 + 108 =? + 27

?=196

4) Answer: C

(64 ÷ 126) * (315 ÷ 16) * ? =40% of 150

(32/63) * (315/16) * ?=60

2 * 5 * ? = 60

?= 6

5) Answer: A

√13689 ÷ 13 + ? % of 320 = 131 * √9

9 + ? % of 320=393

?=120

Directions (6-10) :

6) Answer: C

Total age of the class = 20 * 28 = 560

New total age of the class = 29 * 21 = 609

New student age = 609 – 560 = 49 years

7) Answer: A

SI = P * N * R/100

4800 * 4 * R/100 – 3200 * 5 * R/100 = 160

192R – 160R = 160

32R = 160

R = 5%

8) Answer: C

(Men1 * day 1)/ work 1 = (Men2 * day 2) / work2

(24 * 20)/(1/3) = (24 + x) * 20/(2/3)

48 = 24 + x

x = 24

9) Answer: C

Milk in 20 liters = 3/5 * 20 = 12 liters

Water in 20 liters = 2/5 * 20 = 8 liters

(3x – 12)/(2x – 8 + 5) = 8/7

21x – 84 = 16x – 24

x = 12

Initial quantity of the mixture = 5x = 5 * 12 = 60 liters

10) Answer: A

The ratio of the total number of students in class A to B = 5: 9 (5x, 9x)

9x – 5x = 16

4x = 16

x = 4

Total number of students in class A = 5 * 4 = 20

Total number of students in class B = 9 * 4 = 36

Number of boys in A = 3/5 * 20 = 12

Number of girls in B = 5/9 * 36 = 20

Required ratio = 12: 20

= 3: 5
