Question

No of students in each section are 36 if 12 students are added then section increase by 4 now the no of students in each section are 30 find original no of section

Answer 1

Given That number of students in each section is 36

Let the number of sections be x

So, total number of students would be 36x

Now, 12 students are added in the school.

→ Total number of students = 36x + 12

And, the section is increased by 4, having 30 students in each section

→ Total number of students = 30(x + 4)

→ Total number of students = 30x + 120

But, we have taken that total number of students = 36x + 12

So, equating the two, we get

36x + 12 = 30x + 120

→ 36x - 30x = 120 - 12

→ 6x = 108

→ x = 108/6

→ x = 18

So, the original number of section was 18.
