Answer:
18 students are good in maths and their percentage is 72%
Step-by-step explanation:
The number of people who are not good in maths is 28% × 25 which is
(28/100)× 25
(28/4)×1
=7
So 7 people are not good in maths.
To find those who are good in maths, subtract this number from the total.
25 -7=18
The percentage is =(18/25) ×100
= 18×4
= 72%
