Ques - In my office there are 30% females employees and 30% of these earn greater than Rs. 8,000 per month and 80% of male employees earn less than Rs. 8,000 per month . What is the percentage of employees who earn more than Rs. 8,000 per month?

(a) 30%

(b) 23%

(c) 60%

(d) Can't determined 

Solution - 

Let,

Total number of employees = 100

Female employees = 30% of 100

Female employees = 30

No. of female employees earn greater than 8,000 = 30% of total female employees

No. of female employees earn greater than 8,000 = (30/100) × 30 

No. of female employees earn greater than 8,000 = 9

Male employees = 100 - 30

Male employees = 70

No. of male employees earn less than 8,000 = 80% of total male employees

No. of male employees earn less than 8,000 = (80/100) × 70 

No. of male employees earn less than 8,000 = 56

But,

We don't know that whether there are some male employees who has exactly Rs. 8,000 per month as their salary or not.

Hence,

The correct option is (d) can't determined.
