Question

4. In a class of 40 pupils, the number of girls is three-fifths of the number of boys. Find
the number of boys in the class.
​

Answer 1

Answer:

Let the number of boys be x.

So, number of girls will be 3x/5.

Total number of students = Number of boys + Number of girls

40 = x + 3x/5

40 = 8x/5

25 = x

So, number of boys is 25.
