A store owner had the same number of starfruits, peaches and chikoos at first. After 101 chikoos, some starfruits and peaches were taken out, there were 124 fruits left. There were twice as many starfruits as peaches left. The number of chikoos left was 31 less than the number of starfruits. How many peaches were taken out?

2 u |
1 u |
2 u - 31 |
124 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 31
= 5 u - 31
5 u - 31 = 124
5 u = 124 + 31
5 u = 155
1 u = 155 ÷ 5 = 31
Number of chikoos at first
= 2 u - 31 + 101
= 2 x 31 - 31 + 101
= 62 - 31 + 101
= 132
The number of peaches and chikoos at first was the same.
Number of peaches taken out
= 132 - 1 u
= 132 - 31
= 101
Answer(s): 101
