, 10% of the boys are equal to one-fourth of the girls. What is the ratio of boys and girls in that
school?
(a) 3:2
hs
(0) 4:3​

Answer 1

Solution:

Let the number of boys be 100n.

10% of 100n = 10n

According to the given condition.

¼ × Number of girls = 10n

Number of girls = 40n

Ratio = Number of boys / Number of girls

Ratio = 100n/40n

Ratio = 5 : 2

Therefore, the ratio of boys and girls in the school is 5 : 2.
