Answer:

No. of girls = 30

No of boys = 2/5 × 30 = 12

Step-by-step explanation:

No. of students = 42

Let 'x' be the number of girls.

No. of boys = 2/5 × x = 2x/5

2x/5 + x = 42

2x×1/5×1  +  x×5/1×5 = 42

2x/5 + 5x/5 = 42

7x/5 = 42

7x = 42 × 5

7x = 210

x = 210/7

x = 30

No. of girls = 30

No of boys = 2/5 × 30 = 12

Check ⇒

30 + 2/5 × 30 = 42

30 + 12 = 42

42 = 42

L.H.S = R.H.S

Hence, verified.

The answer is correct.
