A fruit seller had the same number of passion fruits, kiwis and starfruits at first. After 97 starfruits, some passion fruits and kiwis were taken out, there were 115 fruits left. There were five times as many passion fruits as kiwis left. The number of starfruits left was 28 fewer than the number of passion fruits. How many kiwis were taken out?

5 u |
1 u |
5 u - 28 |
115 |
Total number of fruits in the end
= 5 u + 1 u + 5 u - 28
= 11 u - 28
11 u - 28 = 115
11 u = 115 + 28
11 u = 143
1 u = 143 ÷ 11 = 13
Number of starfruits at first
= 5 u - 28 + 97
= 5 x 13 - 28 + 97
= 65 - 28 + 97
= 134
The number of kiwis and starfruits at first was the same.
Number of kiwis taken out
= 134 - 1 u
= 134 - 13
= 121
Answer(s): 121
