A fruit seller had the same number of chikoos, dragonfruits and peaches at first. After 58 peaches, some chikoos and dragonfruits were sold, there were 117 fruits left. There were four times as many chikoos as dragonfruits left. The number of peaches left was 36 less than the number of chikoos. How many dragonfruits were sold?

4 u |
1 u |
4 u - 36 |
117 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 36
= 9 u - 36
9 u - 36 = 117
9 u = 117 + 36
9 u = 153
1 u = 153 ÷ 9 = 17
Number of peaches at first
= 4 u - 36 + 58
= 4 x 17 - 36 + 58
= 68 - 36 + 58
= 90
The number of dragonfruits and peaches at first was the same.
Number of dragonfruits sold
= 90 - 1 u
= 90 - 17
= 73
Answer(s): 73
