Vanessa bought 22 oranges and 16 mangosteens on Wednesday. Each day, she ate 3 oranges and 1 mangosteen. She started eating her fruits on Thursday.

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

	Oranges	Mangosteens
Before	22	16
Change	- 3 u	- 1 u
After	22 - 3 u	16 - 1 u

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

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

22 - 3 u = 16 - 1 u
3 u - 1 u = 22 - 16
2 u = 6

1 u = 6 ÷ 2 = 3

Vanessa ate for 3 days from Thursday onwards.  At the end of Saturday, there would be an equal number of oranges and mangosteens left.

(b)
Number of days from Thursday to Sunday = 4

Number of oranges left on Sunday
= 22 - (3 x 4)
= 22 - 12
= 10

Number of mangosteens left on Sunday
= 16 - (1 x 4)
= 16 - 4
= 12

Number of mangosteens more than oranges
= 12 - 10
= 2

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