Question

in the class of 35 students the number of girls is 2/5 of the boys fine the number of boys in the class​

Answer 1

Answer:

21

Step-by-step explanation:

Number of Girls- 2/5

2/5*35= 14

35-14=21

Answer 2

Total strength of the class = 35.

Let the number of boys be x .

Number of girls = 2/5 of x.

So, x + 2x/5 = 35.

(5x + 2x) / 5 = 35.

( LCM is 5 ).

7x / 5 = 35 .

7x = 35 × 5.

( transposing 5 to RHS ).

7x = 175.

x = 175 / 7 .

( transposing 7 to RHS ).

x = 25.

Hence , there are 25 boys in the class.
