Answer 1

Answer:

R17 700

Step-by-step explanation:

Dumsani earns R42 480 per month. He splits his earnings in the ratio 7:5 and then saves the lesser amount. How much does he save?

Step 1

We have ratio 7:5

The sum of the proportion = 7 + 5 = 12

We are told in the above question, that he saves the lesser amount

The lesser ratio = 5

Hence, the amount he saves is calculated as:

5/12 of R42 480

= 5/12 × R42 480

= 5 × 3540

= R17 700

Therefore, he saves R17 700
