Question

There are 40 students at Bali high who play stringed instruments. Of these, 1/4 play viola, 1/5 play cello, and the rest play violin. How many students play violin?

Answer 1

22 play violin.
1/5 * 40 = 8
1/4 * 40 = 10
8+10=18
40-18=22

22!

Answer 2

22 students

Explanation:

Given,

Total number of students = 40,

∵ Number of students who play viola =
`(1)/(4)` of the total students

=
`(1)/(4)* 40`

= 10

Also, number of students who play cello =
`(1)/(5)` of the total students

=
`(1)/(5)* 40`

= 8

So, the remaining students = total students - students who play viola - students who play cello

= 40 - 10 - 8

= 22

Hence, 22 students play violin.
