Jen bought 33 kiwis and 18 chikoos on Wednesday. Each day, she ate 4 kiwis and 1 chikoo. She started eating her fruits on Thursday.
- At the end of which day would there be an equal number of kiwis and chikoos left? Give your answer in the following format. (Eg Monday)
- How many more chikoos than kiwis were there on Tuesday?

Kiwis |
Chikoos |
| Before |
33 |
18 |
| Change |
- 4 u |
- 1 u |
| After |
33 - 4 u |
18 - 1 u |
(a)
Let the number of days be 1 u.
The number of chikoos and kiwis in the end is equal.
33 - 4 u = 18 - 1 u
4 u - 1 u = 33 - 18
3 u = 15
1 u = 15 ÷ 3 = 5
Jen ate for 5 days from Thursday onwards. At the end of Monday, there would be an equal number of kiwis and chikoos left.
(b)
Number of days from Thursday to Tuesday = 6
Number of kiwis left on Tuesday
= 33 - (4 x 6)
= 33 - 24
= 9
Number of chikoos left on Tuesday
= 18 - (1 x 6)
= 18 - 6
= 12
Number of chikoos more than kiwis
= 12 - 9
= 3
Answer(s): (a) Monday; (b) 3
