35 The number of boys is the repeated identity. Make the number of boys the same. LCM of 3 and 5 is 15.
Number of students who wear hats
= 6 u + 25 u
= 31 u
Total number of students
= 9 u + 6 u + 10 u + 25 u
= 50 u
Percentage of the students in the theme park who wear hats
=
3150 x 100%
= 62%
Answer(s): 62%
