Answer 1

Given,

There are 120 girl and 57 boys in the school.

5% girls leave the school.

No new admission happened.

To find,

The percentage of the boys.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Number of left girl = 120 × 5/100 = 6

Number of presently available girl = 120-6 = 114

Number of total students = 114+57 = 171

Percentage of the boys = 100 × 57/171 = 33.33%

Hence, the percentage of the boys will be 33.33%
