Linda's and Xylia's savings were in the ratio of 4 : 9. Both of them shared the cost of their uncle's gift equally. Linda's remaining savings was ²₅ as much as Xylia's savings. What percentage of her savings did Xylia spend? Correct the answer to 1 decimal place.

	Linda	Xylia	Difference
Before	4x3 = 12 u	9x3 = 27 u	5x3 = 15 u
Change	- 2 u	- 2 u
After	2x5 = 10 u	5x5 = 25 u	3x5 = 15 u

Since Linda and Xylia shared the cost of their uncle's gift equally, the amount each paid for the gift is the same. 

So, the difference in the amounts between Linda and Xylia at first and in the end remains the same.  Make the difference in the amounts between Linda and Xylia at first and in the end the same. LCM of 5 and 3 is 15.

Amount that Xylia spent on the gift
= 27 u - 25 u
= 2 u

Percentage of her savings that Xylia spent
= ²₂₇ x 100%
≈ 7.4%

Answer(s): 7.4%
