Hope it helps you=
Step-by-step explanation:
First Method
This is perhaps a little bit more straightforward. Since we have already been told that there are 40% girls, that means there are 60% boys (100–40).
The answer therefore will be 60% of 40, which is (60/100) * 40 = 24 boys.
Second Method
Pretty much similar to the first one. The only difference is that we find out how many girls. Once we have the numbers of girls, we can then subtract the girls from the total number of students to get the number of boys.
Number of girls = (40/100)*40 = 16 girls
40–16 = 24 boys
