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%
