Cindy bought 30 pomegranates and 15 starfruits on Tuesday. Each day, she ate 4 pomegranates and 1 starfruit. She started eating her fruits on Wednesday.

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

	Pomegranates	Starfruits
Before	30	15
Change	- 4 u	- 1 u
After	30 - 4 u	15 - 1 u

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

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

30 - 4 u = 15 - 1 u
4 u - 1 u = 30 - 15
3 u = 15

1 u = 15 ÷ 3 = 5

Cindy ate for 5 days from Wednesday onwards.  At the end of Sunday, there would be an equal number of pomegranates and starfruits left.

(b)
Number of days from Wednesday to Monday = 6

Number of pomegranates left on Monday
= 30 - (4 x 6)
= 30 - 24
= 6

Number of starfruits left on Monday
= 15 - (1 x 6)
= 15 - 6
= 9

Number of starfruits more than pomegranates
= 9 - 6
= 3

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