Answer: 400 Boys
Explanation:
Given,
Fraction of boys = 5/8
No. of Girls in class = 240
To find,
Total no. of Boys = ?
Let the number of Boys is X
Fraction of girls = 1 - 5/8 = 3/8
So, girls = 3/8 × x
It means, Faction of Girls = 3/8
240 = 3/8 × x
x = 240 × 8 /3 = 640
Number of boys = 5/8 of 640
= 5/8 × 640
= 400
Therefore, Total no. of boys in a school are 400.
