A. 6 to 5
B. 5 to 4
C. 3 to 2
D. 4 to 3
E. 5 to 2
Let total no of employees be 100

Male employees = 60 ; Female employees = 40

Quote:
25 percent of the male employees and 30 percent of the female employees are stockbrokers.

So, 15 male employees and 12 female employees are stock brokers.

Quote:
what is the ratio of the number of male stockbrokers to the number of female stockbrokers?

M : S = 15 : 12 => 5 : 4, Answer must be (B)
