Let E be total no. of employees and F be total no of female employees.

Question asked what is F/E X 100%?

No. of female employees with Masters = 0.3 x E (From the question)

No. of female employees without masters = 0.2 x F (From the question)
Therefore No. of female employees with masters = F - 0.2 F = 0.8 F

The 2 expressions equal each other therefore 0.8F = 0.3E; F/E = 0.3/0.8 = 37.5%

Ans: D
