Tiffany bought 30 chikoos and 18 passion fruits on Thursday. Each day, she ate 4 chikoos and 1 passion fruit. She started eating her fruits on Friday.

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

	Chikoos	Passion Fruits
Before	30	18
Change	- 4 u	- 1 u
After	30 - 4 u	18 - 1 u

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

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

30 - 4 u = 18 - 1 u
4 u - 1 u = 30 - 18
3 u = 12

1 u = 12 ÷ 3 = 4

Tiffany ate for 4 days from Friday onwards.  At the end of Monday, there would be an equal number of chikoos and passion fruits left.

(b)
Number of days from Friday to Tuesday = 5

Number of chikoos left on Tuesday
= 30 - (4 x 5)
= 30 - 20
= 10

Number of passion fruits left on Tuesday
= 18 - (1 x 5)
= 18 - 5
= 13

Number of passion fruits more than chikoos
= 13 - 10
= 3

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