Number of pupils from Club Q at first in percent
= 100% - 40%
= 60%
Number of pupils from Club Q at first
= 60% x 60
=
60100 x 60
= 36
Number of pupils in Club P remains unchanged.
6 u = 60
1 u = 60 ÷ 6 = 10
Number of pupils from Club Q in the end
= 5 u
= 5 x 10
= 50
Number of pupils joined Club Q
= 50 - 36
= 14
