Instructions

In a team there are 240 members (males and females). Two-third of them are males. Fifteen percent of males are graduates. Remaining males are nongraduates. Three-fourth of the females are graduates. Remaining females are non-graduates

Question 40

What is the ratio between the total number of males and the number of females who are non-graduates?

Solution

Total members in the team = 240

Males = $$\ \frac{\ 2}{3}\times\ 240$$ = 160
Females = $$\ \frac{\ 1}{3}\times\ 240$$ = 80

Number of females who are non graduates = $$\ \frac{\ 1}{4}\times\ 80$$ = 20

ratio between the total number of males and the number of females who are non-graduates

= 160:20

=8:1

B is the correct answer.
