A grocer had the same number of starfruits, kiwis and guavas at first. After 126 guavas, some starfruits and kiwis were given away, there were 136 fruits left. There were thrice as many starfruits as kiwis left. The number of guavas left was 11 fewer than the number of starfruits. How many kiwis were given away?

3 u |
1 u |
3 u - 11 |
136 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 11
= 7 u - 11
7 u - 11 = 136
7 u = 136 + 11
7 u = 147
1 u = 147 ÷ 7 = 21
Number of guavas at first
= 3 u - 11 + 126
= 3 x 21 - 11 + 126
= 63 - 11 + 126
= 178
The number of kiwis and guavas at first was the same.
Number of kiwis given away
= 178 - 1 u
= 178 - 21
= 157
Answer(s): 157
