Question

In 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

Step-by-step explanation:

The no. of students - 40

no. of boys - 3/5

Therefore no. of boys = 3/5 × 40 = 24.

Answer 2

Answer:

Let the number of boys be x,

So, Number of girls=3/5x

Hence, according to the question:

3/5x + x = 40(sum of number of boys and girls)

(3x + 5x)/5=40

8x/5=40

therefore,x=25

So, the number of boys is 25
