Q: An orphanage owner fed some biscuits to the orphans for afternoon tea. One day, he gave each child 4 biscuits and had 2 biscuits left.

To give each child 6 biscuits, he would need another 22 biscuits. How many children were in his orphanage?

A: It seems like a difficult question at first glance. But if you understand the question, you can solve the question with simple steps. For easy understanding, draw a diagram to show the relationship of the number of children and the number of biscuits. Once you get the diagram correct, that means you have understood the question and it is easier for you to find the answer.

4 biscuits or 6 biscuits?

To give the children 6 biscuits each, he would need another 22 biscuits. That means 2 extra biscuits + 22 biscuits = 24 biscuits to be equally divided to the children.

2 + 22 = 24

There is an increase of 2 biscuits for each child, from 4 to 6.

6 – 4 = 2

To find the number of children, we divide the biscuits equally,

24 ÷ 2 = 12

There are 12 children in the orphanage.

Checking the answer

When there are only 4 biscuits to each child,

(4 x 12) + 2 = 50

The owner has 50 biscuits initially, as there are 2 biscuits left.

He adds in another 22 biscuits and now he has 72 biscuits.

50 + 22 = 72

72 biscuits are divided equally by 12 children, each child gets 6 biscuits.

72 ÷ 12 = 6

Thus, the answer, 12 children, is correct.

Note to parents: If your child encounters difficult questions, asks him / her to check the answer. Checking the answer is a good way to reassure your child that he / she has answered the question correctly.
