In an office, 70% of the total number of employees are females. 80% of the total number of employees, including 85 males, got promotion. If there are 105 females, then what percentage of female employees got the promotion?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. (100/3)%

Let the total number of employees in the office = 100x

Number of females = 70x

Number of males = 100x – 70x = 30x

So,

70x = 105

⇒ x = 105/70 = 1.5

⇒ 30x = 1.5 × 30 = 45

So, there are 105 females and 45 males in the office.

Hence, total number of employees = 45 + 105 = 150

Number of employees who got promotion = 80x = 120

So, number of females who got promotion = 120 – 85 = 35

Hence, percentage of female employees who got promotion = (35/105) × 100 = (100/3)%
