35 The number of girls is the repeated identity. Make the number of girls the same. LCM of 3 and 5 is 15.
Number of students who do not wear hats
= 9 u + 10 u
= 19 u
Total number of students
= 9 u + 6 u + 10 u + 25 u
= 50 u
Percentage of the students in the theme park who do not wear hats
=
1950 x 100%
= 38%
Answer(s): 38%
