Penelope bought 28 starfruits and 12 pomegranates on Saturday. Each day, she ate 5 starfruits and 1 pomegranate. She started eating her fruits on Sunday.

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

	Starfruits	Pomegranates
Before	28	12
Change	- 5 u	- 1 u
After	28 - 5 u	12 - 1 u

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

The number of pomegranates and starfruits in the end is equal.

28 - 5 u = 12 - 1 u
5 u - 1 u = 28 - 12
4 u = 16

1 u = 16 ÷ 4 = 4

Penelope ate for 4 days from Sunday onwards.  At the end of Wednesday, there would be an equal number of starfruits and pomegranates left.

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

Number of starfruits left on Thursday
= 28 - (5 x 5)
= 28 - 25
= 3

Number of pomegranates left on Thursday
= 12 - (1 x 5)
= 12 - 5
= 7

Number of pomegranates more than starfruits
= 7 - 3
= 4

Answer(s): (a) Wednesday; (b) 4
