Answer 2

Answer:

if , students good in math = 60%

Total no. of students= 25

then, percent are used to have 100.

Total no. Of student = 25

Therefore, Students not good in maths = total no. of students - no. Of students good in maths

= 25–15

= 10

The no. Of students not good in maths are 10.
