25 The number of boys is the repeated identity. Make the number of boys the same. LCM of 1 and 5 is 5.
Number of students who do not wear caps
= 2 u + 5 u
= 7 u
Total number of students
= 2 u + 3 u + 5 u + 40 u
= 50 u
Percentage of the students in the theme park who do not wear caps
=
750 x 100%
= 14%
Answer(s): 14%
