There were thrice as many starfruits as kiwis left. The number of passion fruits left was 20 less than the number of starfruits. How many kiwis were taken out?

3 u |
1 u |
3 u - 20 |
113 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 20
= 7 u - 20
7 u - 20 = 113
7 u = 113 + 20
7 u = 133
1 u = 133 ÷ 7 = 19
Number of passion fruits at first
= 3 u - 20 + 116
= 3 x 19 - 20 + 116
= 57 - 20 + 116
= 153
The number of kiwis and passion fruits at first was the same.
Number of kiwis taken out
= 153 - 1 u
= 153 - 19
= 134
Answer(s): 134
