35 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 do not wear caps
= 3 u + 10 u
= 13 u
Total number of students
= 3 u + 2 u + 10 u + 5 u
= 20 u
Percentage of the students in the bird park who do not wear caps
=
1320 x 100%
= 65%
Answer(s): 65%
