35 The number of girls is the repeated identity. Make the number of girls the same. LCM of 7 and 5 is 35.
Number of students who wear spectacles
= 14 u + 5 u
= 19 u
Total number of students
= 21 u + 14 u + 10 u + 5 u
= 50 u
Percentage of the students in the theme park who wear spectacles
=
1950 x 100%
