Xuan bought 26 kiwis and 14 mangosteens on Saturday. Each day, she ate 4 kiwis and 1 mangosteen. She started eating her fruits on Sunday.

1. At the end of which day would there be an equal number of kiwis and mangosteens left? Give your answer in the following format. (Eg Monday)
2. How many more mangosteens than kiwis were there on Thursday?

	Kiwis	Mangosteens
Before	26	14
Change	- 4 u	- 1 u
After	26 - 4 u	14 - 1 u

(a)
Let the number of days be 1 u.

The number of mangosteens and kiwis in the end is equal.

26 - 4 u = 14 - 1 u
4 u - 1 u = 26 - 14
3 u = 12

1 u = 12 ÷ 3 = 4

Xuan ate for 4 days from Sunday onwards.  At the end of Wednesday, there would be an equal number of kiwis and mangosteens left.

(b)
Number of days from Sunday to Thursday = 5

Number of kiwis left on Thursday
= 26 - (4 x 5)
= 26 - 20
= 6

Number of mangosteens left on Thursday
= 14 - (1 x 5)
= 14 - 5
= 9

Number of mangosteens more than kiwis
= 9 - 6
= 3

Answer(s): (a) Wednesday; (b) 3
