Answer 1

Hey there,

● Answer -
42 sections

● Explaination -
Let n be number of sections in exam unit of school.
Each section has same no of students in it.

Thus total number of students in school will be -
N = Sn
N = n(n+1)/2

Substituting values,
903 = n(n+1)/2
1806 = n(n+1)
42 × 43 = n (n+1)
n = 42

Therefore, exam hall for 10th ans 12th board exam has 42 sections in it.

Hope this helps you...
