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 has 42 sections in it.

Hope this helps you...

Answer 2

Answer:

3 or 9

Step-by-step explanation:

As we can see the data given in q. is not complete, i.e we also need that how much students are there in one section but it's not given. It means this q. might be a multiple choice q. where you might have given options. So with those options we can check whatever no. divides 963 perfectly will be our answer.

And here I can see 963 is divisible by 3 and 9 so ans. will be according to options.

Hope it will help...
