Fiona bought 23 kiwis and 13 persimmons on Monday. Each day, she ate 3 kiwis and 1 persimmon. She started eating her fruits on Tuesday.

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

	Kiwis	Persimmons
Before	23	13
Change	- 3 u	- 1 u
After	23 - 3 u	13 - 1 u

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

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

23 - 3 u = 13 - 1 u
3 u - 1 u = 23 - 13
2 u = 10

1 u = 10 ÷ 2 = 5

Fiona ate for 5 days from Tuesday onwards.  At the end of Saturday, there would be an equal number of kiwis and persimmons left.

(b)
Number of days from Tuesday to Sunday = 6

Number of kiwis left on Sunday
= 23 - (3 x 6)
= 23 - 18
= 5

Number of persimmons left on Sunday
= 13 - (1 x 6)
= 13 - 6
= 7

Number of persimmons more than kiwis
= 7 - 5
= 2

Answer(s): (a) Saturday; (b) 2
