Question

Rate

Sarita from Singapore was preparing to go to South Africa for 3 months as an exchange student, so

she decided to exchange money from Singapore currency to South African currency to bear the

expenses there.

.She went to the shop to change some Singapore dollars (SGD) into South African rand (ZAR).

1) Sarita found out that the exchange rate between Singapore dollars and South African rand was:



1 SGD = 4.2 ZAR

Sarita changed 3000 Singapore dollars into South African rand at this exchange rate.

How much money in South African rand did Sarita get?

2) On returning to Singapore after 3 months, Sarita had 3 900 ZAR left. She changed this back to

Singapore dollars, noting that the exchange rate had changed to:

1 SGD = 4.0 ZAR

How much money in Singapore dollars did Sarita get?

3) During these 3 months the exchange rate had changed from 4.2 to 4.0 ZAR per SGD.

Was it in Sarita’s favour that the exchange rate now was 4.0 ZAR instead of 4.2 ZAR, when she

changed her South African currency back to Singapore currency? Give an explanation to support​
