Number of students from Club F at first in percent
= 100% + 25%
= 125%
Number of students from Club F at first
= 125% x 48
=
125100 x 48
= 60
Number of students in Club E remains unchanged.
4 u = 48
1 u = 48 ÷ 4 = 12
Number of students from Club F in the end
= 3 u
= 3 x 12
= 36
Number of students from Club F who left
= 60 - 36
= 24
Answer(s): 24
