Question

Melissa is 13 years old. Becky is 12 years old. Daniel is 10 years old. Melissa, Becky and Daniel share £42 in the ratio of their ages. Becky decided to save a third of her share. How much will Becky have to spend?

Answer 1

Answer: Becky will have to spend £ 9.6 .

Explanation:

The ratio of their ages will be:

Melissa : Becky : Daniel = 13 : 12 : 10

Total amount share = £42

Share of Becky =
`(12)/(12+13+10)*42`

`=(12)/(35)*42\\\\= 14.4`

Hence, Becky's share = £14.4

Becky decided to save a third of her share.

Then, Amount she spend =
`14.4-\frac13 * 14.4`

`=14.4-4.8\\=9.6`

hence, Becky will have to spend £ 9.6 .
