Difference |
Before |
4x3 = 12 u |
9x3 = 27 u |
5x3 = 15 u |
Change |
- 7 u |
- 7 u |
|
After |
1x5 = 5 u |
4x5 = 20 u |
3x5 = 15 u |
Since Abi and Jade shared the cost of their auntie's present equally, the amount each paid for the present is the same.
So, the difference in the amounts between Abi and Jade at first and in the end remains the same. Make the difference in the amounts between Abi and Jade at first and in the end the same. LCM of 5 and 3 is 15.
Amount that Jade spent on the present
= 27 u - 20 u
= 7 u
Percentage of her savings that Jade spent
=
727 x 100%
≈ 25.9%
Answer(s): 25.9%
