Q 2 - In a leading MNC, there are 51 male employees who are over 150 cm tall. If these constitute three-fourths of the male employees and the total number of male employees is two-thirds of the total number of employees in the class, what is the number of female employees in the class?

Options :

A - 0

C - 1

D - 4

Answer : D

Explanation

Let the number of male employees be x. Then, (3/4) x = 51 or x = 51 × (4/3) = 68.If total number of students is y, then (2/3) y = 68 or y = 68 × (3/2) = 72.Therefore Number of females in the MNC = (72 - 68) = 4.
