Question

A teacher has 45 chocolates. After giving two chocolates to each student, she is left with 7 chocolates. How many students are there in the class ?

Answer 1

Let the number of students in the class be x
Total number of chocolates distributed = 2x
Total number of chocolates left with the teacher = 7
`2x + 7 = 45`
`rArr 2x = 45 - 7`
`rArr 2x = 38 rArr x = 19`
There are 19 students in the class
