Question

A school of 800 students has 60% girls.

Of them, 50% go to music classes. 10% of those music students are into volleyball. If the team is
32 Girls, how many are not into music?

Answer 1

8

Explanation:

I will just calculate the population of every detail for ease.
800 total students.
800 * 60% or 0.6 = 480
480 girls.
480 * 50% or 0.5 = 240
240 music class girls.
240 * 10% or 0.1 = 24
24 music class girls.
so 24 music class girls that are into volleyball and 32 team girls.
32-24 = 8
8 of the team girls are not into music.
