45 The number of girls is the repeated identity. Make the number of girls the same. LCM of 1 and 5 is 5.
Number of students who wear caps
= 1 u + 35 u
= 36 u
Total number of students
= 4 u + 1 u + 10 u + 35 u
= 50 u
Percentage of the students in the fun fair who wear caps
=
3650 x 100%
= 72%
Answer(s): 72%
