(D) 1.8
(E) 18

Answer: A: 0.0018 Explanation: 0.006 × 0.02 × 0.0036 ÷ (0.06 × 0.004) = x (0.006 × 0.02 × 0.0036) / (0.06 × 0.004) = x X = 0.0018

2) Directions: What value should come in place of (?) in the following questions? (3.03 + 7.07)2 – x = 5 × 1.04 × 6.8

(A) 66.65
(B) 65.66
(C) 61.13
(D) 72.15
(E) 59.17

Answer: A: 66.65 Explanation: (3.03 + 7.07)2 – x = 5 × 1.04 × 6.8 (10.1)2 – x = 35.36 102.01 – x = 35.36 X = 102.01 – 35.36 X = 66.65

3) Directions: In the following questions, two equations I and II are given. You have to solve both the equations and give Answer. I. x2 – 5x – 24 =0 II. y2 – 7y – 18 = 0 

(A) x > y
(B) x ≥ y
(C) x < y
(D) x ≤ y
(E) x = y or the relation cannot be established

Answer: E: x = y or the relation cannot be established Explanation: Solution: I.

Source: safalta

x2 – 5x – 24 =0 x2 – 8x + 3x – 24 = 0 x(x – 8) + 3(x – 8) = 0 x = +8, -3 II. y2 – 7y – 18 = 0 y2 – 9y + 2y – 18 = 0 y(y – 9) + 2(y – 9) y = +9 , -2 Hence, can’t be determined

4) Directions: In the following questions, two equations I and II are given. You have to solve both the equations and give Answer. I. (343x)1/3 = √2401 II. √4y = (256)1/2

(A) x > y 
(B) x ≥ y
(C) x < y
(D) x ≤ y
(E) x = y or the relation cannot be established

Answer: E: x = y or the relation cannot be established Explanation: Solution: I. (343x)1/3 = √2401 7x1/3 = ±49 x = ±343 II. √4y = (256)1/2 4y = 256 y = 64 Hence, Cant be determined
