Roshel's and Winnie's savings were in the ratio of 2 : 5. Both of them shared the cost of their father's present equally. Roshel's remaining savings was ¹₅ as much as Winnie's savings. What percentage of her savings did Roshel spend? Correct the answer to 1 decimal place.

	Roshel	Winnie	Difference
Before	2x4 = 8 u	5x4 = 20 u	3x4 = 12 u
Change	- 5 u	- 5 u
After	1x3 = 3 u	5x3 = 15 u	4x3 = 12 u

Since Roshel and Winnie shared the cost of their father's present equally, the amount each paid for the present is the same. 

So, the difference in the amounts between Roshel and Winnie at first and in the end remains the same.  Make the difference in the amounts between Roshel and Winnie at first and in the end the same. LCM of 3 and 4 is 12.

Amount that Roshel spent on the present
= 8 u - 3 u
= 5 u

Percentage of her savings that Roshel spent
= ⁵₈ x 100%
≈ 62.5%

Answer(s): 62.5%
