Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 18.
Given, number of employees in department E = 216
⇒ 12% = 216
Now, number of employees in department A = 20 × 18 = 360
Number of males in department A = 45% of 360
⇒ 162
Number of employees in department C = 18 × 18 = 324
Female employees in department C = 324 × 5/9
⇒ 180
Required difference = 180 - 162 = 18
