$<b><marquee behaviour = ''alternative">Answer is 16</marquee>$

Step-by-step explanation:

Let No. of Girls = X

So boys 2/5 of girls so Boys = 2x/5

Now Total Students are x + 2x/5 = 56

(5x +2x) / 5 = 56

7x/5 = 56

X = (56x5)/7

X = 40

So Girls = X = 40

So boys 2/5 of girls 40 × 2/5 = 16

or 56- Girls = 56 - 40 = 16

Answer 2

Answer:

=> Correct answer is 16.

Explanation below:-

Let No. of Girls = X

So boys 2/5 of girls so Boys = 2x/5

Now Total Students are x + 2x/5 = 56

(5x +2x) / 5 = 56

7x/5 = 56

X = (56x5)/7

X = 40

So Girls = X = 40

So boys 2/5 of girls 40 × 2/5 = 16

or 56- Girls = 56 - 40 = 16 ans.
