lets say no. of girls is x

total sum of ages of the class:

60 boys * 10.6 yrs + x girls * 10.1 years = (60 + x) * 10.5 years

or, 636 + 10.1x = 630 + 10.5x

or, 0.4x = 6

x = 6/0.4

no. of girls = 15

A fourth of the class are boys, which can be expressed as a fraction as 1/4. Since the class is made up of only boys and girls, and a fourth of the class are boys, the remaining part of the class must be girls. To find the fraction of the class that are girls, you can subtract 1/4 from 1. 1 - 1/4 = 3/4 So, 3/4 of the class are girls.

It is not opssible to give a sensible answer to this question. 46+58 = 104. So if the class has 46% girls and 58% boys then the class has 4% who are simultaneously girls and boys.
