**Upper primary school mathematics question UPQ449**

In the home appliance sale exhibition at Singapore Expo during the Great Singapore Sale, a fridge is selling at very good price as well as the buyer will get additional 3% cash off from the display price and the 7% GST is absorded buy the exhibitor. Sarin’s father is eyeing on a Panaso fridge that priced as $1467 on display at the exhibition.

a) How much he needs to pay for the Panaso fridge after 3% cash off and 7% GST absorbed?

b) What is the total percentage of saving he got from buying the fridge at the exhibition?

Solution:

The price of the fridge at the sale = $1467

3% cash off on the price = 1467 × 3% = $44.01

The price of the fridge after further 3% cash off = 1467 – 44.01 = $1422.99

The price is includsive of 7% GST

107% ==> 1422.99

1% ==> $13.29897

100% ==> $1329.90

The amount that Sarin’s father pay for the fridge = $1329.90

The total amount he save = 2099 – 1329.90 = $769.10

The total percentage of saving = 769.10/2099 × 100% = 36.64%

Note: You did not get extra 10% saving from the cash off and GST absorbed as it is based on the display price.
