A fruit seller had the same number of dragonfruits, chikoos and starfruits at first. After 119 starfruits, some dragonfruits and chikoos were sold, there were 122 fruits left. There were four times as many dragonfruits as chikoos left. The number of starfruits left was 13 less than the number of dragonfruits. How many chikoos were sold?

4 u |
1 u |
4 u - 13 |
122 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 13
= 9 u - 13
9 u - 13 = 122
9 u = 122 + 13
9 u = 135
1 u = 135 ÷ 9 = 15
Number of starfruits at first
= 4 u - 13 + 119
= 4 x 15 - 13 + 119
= 60 - 13 + 119
= 166
The number of chikoos and starfruits at first was the same.
Number of chikoos sold
= 166 - 1 u
= 166 - 15
= 151
Answer(s): 151
