Total students = 25
% of students good in English = 72%
No. of students good in English = 72% of 25
= 72/100 × 25
= 1800/100
= 18
No. of students not good in English = 25-18
( Total students - no of students good in English)
= 7
So, there are 18 students who are good in English and 7 students who are not good in English
