Answer:
Total number of student = 56
Let the number of Girls be = x
Then number of boys will be= 2/5x.
According to question:-x+2/5 x = 56(5/5)x+ (2/5)x = 56 {by taking LCM}(7/5)x = 567x = 56×5x = 56×5/7x = 8×5 {56 is divided by 7}x = 40
So, number of girls = x= 40Number of boys = 2/5 × x= 2/5 × 40= 2 × 8= 16Hope it helps.

7X/5=56
X= 56×5/7
X= 40
so Girls X= 40
so boys 2/5 of girls = 40×2/5 =16
