Answers :

1) Answer: D

Pass marks = 40/100 * x

40/100 * x * 120/100 = 360

x = 750

2) Answer: E

(7k + x)/(5k + x) = 4/3

We cannot be determined

3) Answer: D

12 * 75/100 = CP * 120/100

CP = Rs.7.5

Required percent = (10 – 7.5)/7.5 * 100

= 33(1/3)%

4) Answer: C

CA = P * (1 + R/100)ⁿ

CA for 11 years = P * (1 + R/100)¹¹  —–(1)

CA for 9 years = P * (1 + R/100)⁹——(2)

From (1) and (2)

(1 + R/100)² = 36/25

(1 + R/100) = 6/5

100 + R = 120

R = 20%

5) Answer: E

Downstream speed = 45/5 = 9 kmph

Upstream speed = 15/3.75 = 4 kmph

Required ratio = (9 – 4)/2:(9 + 4)/2

= 5:13

6) Answer: C

(3283/67) – (377/13) = ?

49 – 29 = ?

? = 20

7) Answer: A

(44/395) * (79/352) * ? = 5

1/5 * 1/8 * ? = 5

? = 200

8) Answer: D

√6561 + √3721 – √1369 = ?

81 + 61 – 37 = ?

? = 105

9) Answer: C

(0.64)⁷⁸ ÷ (0.512)³⁹ = (0.8)^?

0.8^{(78 * 2 – 39 * 3)} = (0.8)^?

? = 39

10) Answer: B

35 * 4 – 21 * 5 = ?

140 – 105 = ?

? = 35
