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 glasses
= 2 u + 20 u
= 22 u
Total number of students
= 2 u + 3 u + 20 u + 25 u
= 50 u
Percentage of the students in the theme park who do not wear glasses
=
2250 x 100%
= 44%
Answer(s): 44%
