Question

72% of 25 students are good at English.How many are not good at it?

Answer 1

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
