Question

Rohan bought a pack of 100 chocolates on his birthday to distribe in class . After giving two chocolates to each student and his class teacher,he is left with ten chocolates. how many students are there in the class

Answer 1

The number of students of class is 46

Answer 2

Let the no. of chocolates given be x.

A/q, 

                100 - x = 10

⇒   100- 10 = x

⇒   90 = x

∴ x = 90

  So, chocolate was given to 90/2 = 45 people

          But, there was one teacher also.

So, no. of students = 45-1 = 44
