? % of (75 × 4 – 150) = 420 + 752

Directions: What value should come in the place of (?) in the following questions.

Q. ? % of (75 × 4 – 150) = 420 + 752

A. 4280

B. 4520

C. 4030

D. 5060

E. None of these

Sol:

x % of (75 × 4 – 150) = 420 + 752

(x/100)*(300 – 150) = 420 + 5625

(x/100)*150 = 6045

3x/2 = 6045

x = 6045*(2/3) = 4030
