Upper primary school mathematics question UPQ553

Sarin’s mother purchases the household necessities from the supermarket weekly.

The pie chart below shows how she spent her money on the items weekly.

She spent $225 more on cloths than on food.

How much did she spend on sundry items weekly?

UPQ553-1

 Solution:

From the pie chart,

The spending on Food = $75

Given the spending on the cloth is $225 more than Food

The spending on the cloth = 225 + 75 = $300

The fraction of spending on Sundry = 1/4

Hence, the fraction of spending on Food and cloth items = 1 – 1/4 = 3/4

The total amount spends on the food and cloth = 75 +300 = $375

3/4 ==>$375

1/4 ==> 375 ÷ 3 = $125

The amount she spends on Sundry items weekly is $125
