Answer 2

Answer :

The number of boys in a class = 25.

Given :

Number of total students in a class = 40.

The number of girls is 3/5 of the number of boys.

To Find :

The number of boys.

Solution :

Let,

The number of boys be x.

According to the question,

The number of girls is 3/5 of the number of boys.

So, the number of girls be x × 3/5.

Given,

Number of total students in a class is 40.

So,

=> Number of boys + Number of girls = Number of total students

=> x + x × 3/5 = 40

=> x + 3x/5 = 40

=> (x × 5) + 3x / 5 = 40

=> 5x + 3x / 5 = 40

=> 5x + 3x = 40 × 5

=> 8x = 200

=> x = 200/8

=> x = 25

Since, the value of x is 25.

That means,

Number of boys = x = 25.

Hence,

The number of boys in a class is 25.
