A store owner had the same number of grapefruits, starfruits and chikoos at first. After 142 chikoos, some grapefruits and starfruits were set aside, there were 171 fruits left. There were five times as many grapefruits as starfruits left. The number of chikoos left was 38 fewer than the number of grapefruits. How many starfruits were set aside?

5 u |
1 u |
5 u - 38 |
171 |
Total number of fruits in the end
= 5 u + 1 u + 5 u - 38
= 11 u - 38
11 u - 38 = 171
11 u = 171 + 38
11 u = 209
1 u = 209 ÷ 11 = 19
Number of chikoos at first
= 5 u - 38 + 142
= 5 x 19 - 38 + 142
= 95 - 38 + 142
= 199
The number of starfruits and chikoos at first was the same.
Number of starfruits set aside
= 199 - 1 u
= 199 - 19
= 180
Answer(s): 180
