The pie chart below shows how Sarin family spending in a typical month.

The family spend the same amount of money on utilities, sundries and clothes.

The amount spent on utilities and food is 50% of the family total spending.

What fraction of his allowance does the family spend on food?

Solution:

From the pie chart,

The fraction of spending on Transportation = 1/4

The utilities and Food spending are 50%,

In fraction,

It is 1/2 or 2/4 of the total family spending.

The fraction of spending on Sundries and clothes = 1 – 2/4 – 1/4 = 1/4

Since same amount spend on Sundries, clothes and utilities,

The fraction of spending on Sundries = 1/4 ÷ 2 = 1/8

The fraction of spending on utilities = 1/8

Hence,

The fraction of spending on food = 1/2 – 1/8 = 3/8
