One third of the boys and one half of the girls of a college participated in a social work project. If the number of participating students is 300 out of which 100 are boys, what is the total number of students in the college?

(A) 500

(B) 600

(C) 700

(D) 900

Ans: C

Number of boys who participate = 100.

∴ $${1}/{3}$$ of boys = 100 or total number of boys = 300.

Number of girls who participate = 200.

∴ $${1}/{2}$$ of girls = 200 or total number of girls = 400.

Hence, total number of students = (300 + 400) = 700.
