Upper primary school mathematics question UPQ443

Sarin’s father likes to buy some business shirts during the Great Singapore Sale. He likes to be able to buy as many brands of shirt as possible with the amount of money that he had. If he has only \$130 and to have bigger amount of saving which are the brands of shirt should he buy and what is the total percentage of saving?

Solution:

The amount of money that Sarin’s father has is \$130

It is not enough to buy all 4 brands of shirt.

He can buy maximum only 3 brands of shirt = 39 + 29 + 59 = \$127

He needs to choose among the Feraud shirt and Goldlion shirt

To achieve maximum saving,

The brands of shirt he can buy are Renoma, Arnold Palmer and Feraud.

The total price of the three brands = 79.90 + 53 + 119 = \$251.90

The total percentage of saving = 124.90/251.90 × 100% ≈ 49.58
