Roshel bought 28 passion fruits and 13 kiwis on Tuesday. Each day, she ate 4 passion fruits and 1 kiwi. She started eating her fruits on Wednesday.

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

	Passion Fruits	Kiwis
Before	28	13
Change	- 4 u	- 1 u
After	28 - 4 u	13 - 1 u

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

The number of kiwis and passion fruits in the end is equal.

28 - 4 u = 13 - 1 u
4 u - 1 u = 28 - 13
3 u = 15

1 u = 15 ÷ 3 = 5

Roshel ate for 5 days from Wednesday onwards.  At the end of Sunday, there would be an equal number of passion fruits and kiwis left.

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

Number of passion fruits left on Monday
= 28 - (4 x 6)
= 28 - 24
= 4

Number of kiwis left on Monday
= 13 - (1 x 6)
= 13 - 6
= 7

Number of kiwis more than passion fruits
= 7 - 4
= 3

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