Kylie's and Pamela's savings were in the ratio of 4 : 7. Both of them shared the cost of their auntie's gift equally. Kylie's remaining savings was ¹₃ as much as Pamela's savings. What percentage of her savings did Pamela spend? Correct the answer to 1 decimal place.

	Kylie	Pamela	Difference
Before	4x2 = 8 u	7x2 = 14 u	3x2 = 6 u
Change	- 5 u	- 5 u
After	1x3 = 3 u	3x3 = 9 u	2x3 = 6 u

Since Kylie and Pamela shared the cost of their auntie's gift equally, the amount each paid for the gift is the same. 

So, the difference in the amounts between Kylie and Pamela at first and in the end remains the same.  Make the difference in the amounts between Kylie and Pamela at first and in the end the same. LCM of 3 and 2 is 6.

Amount that Pamela spent on the gift
= 14 u - 9 u
= 5 u

Percentage of her savings that Pamela spent
= ⁵₁₄ x 100%
≈ 35.7%

Answer(s): 35.7%
