Emma bought 27 pomegranates and 12 lemons on Saturday. Each day, she ate 4 pomegranates and 1 lemon. She started eating her fruits on Sunday.

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

	Pomegranates	Lemons
Before	27	12
Change	- 4 u	- 1 u
After	27 - 4 u	12 - 1 u

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

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

27 - 4 u = 12 - 1 u
4 u - 1 u = 27 - 12
3 u = 15

1 u = 15 ÷ 3 = 5

Emma ate for 5 days from Sunday onwards.  At the end of Thursday, there would be an equal number of pomegranates and lemons left.

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

Number of pomegranates left on Friday
= 27 - (4 x 6)
= 27 - 24
= 3

Number of lemons left on Friday
= 12 - (1 x 6)
= 12 - 6
= 6

Number of lemons more than pomegranates
= 6 - 3
= 3

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