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.
