A stallholder had the same number of kiwis, passion fruits and chikoos at first. After 87 chikoos, some kiwis and passion fruits were thrown away, there were 149 fruits left. There were four times as many kiwis as passion fruits left. The number of chikoos left was 40 fewer than the number of kiwis. How many passion fruits were thrown away?

	Kiwis	Passion Fruits	Chikoos	Total
Before	1	1	1
Change	- ?	- ?	- 87
After	4 u	1 u	4 u - 40	149

Total number of fruits in the end
= 4 u + 1 u + 4 u - 40
= 9 u - 40

9 u - 40 = 149
9 u = 149 + 40
9 u = 189

1 u = 189 ÷ 9 = 21

Number of chikoos at first
= 4 u - 40 + 87
= 4 x 21 - 40 + 87
= 84 - 40 + 87
= 131

The number of passion fruits and chikoos at first was the same.

Number of passion fruits thrown away
= 131 - 1 u
= 131 - 21
= 110

Answer(s): 110
