Question 32

Thirty per cent of the employees of a call centre are males. Ten per cent of the female employees have an engineering background. What is the percentage of male employees with engineering background?

A. Twenty five per cent of the employees have engineering background.

B. Number of male employees having an engineering background is 20% more than the number of female employees having an engineering background

Solution

Let the total number of employees be 100k.
Number of males = 30k. Number of females = 70k.
Number of female engineers = 7k.
From statement A, number of male engineers = 25k - 7k = 18k.
From statement B, number of male engineers = (6/5)*7k.
Therefore, percentage of male engineers can be calculated.
So, the question can be answered by either statement alone.
