The ratio of Alice’s savings to Cat’s savings was 1:3.
They shared the cost of a present in the ratio of 2:5.
Alice used 1/3 of her savings while Cat had $57 left after buying the present.
How much was the present?

Hi

Total amount of “sitting time” ---- 27*5 ----- 135

“sitting time” per passenger ----- 135/30 ----- 4.5

“standing time” per passenger ----- 5 - 4.5 ----- 0.5

Hope this helps.

Best wishes

Hi, can help me solve this question?
Joamme & tomomi bought the same bag from the same shop when they went shopping together. joanne spent 75% of her money on the bag & tomoni spent 2/3 of hers. What % of their total sum of money was the cost of a bag if the girls had $100 left together? (round off to nearest tenth). Thank :love:
