Question

40% of a High School band plays brass instruments. 28 students play a brass instrument, how many students are in the band?

Answer 1

There are 70 people in the band. This is because 28 of 70 is 40%.

Answer 2

Let the total students in the band be = x

Number of students who play brass instrument = 28

This 28 is 40 percent of x

So, the number of students will be =

`(40x)/(100)=28`

`40x=2800`

`x=70`

So total number of students in the band are 70.
