A fruit seller had the same number of kiwis, chikoos and mangosteens at first. After 97 mangosteens, some kiwis and chikoos were sold, there were 192 fruits left. There were four times as many kiwis as chikoos left. The number of mangosteens left was 24 less than the number of kiwis. How many chikoos were sold?

4 u |
1 u |
4 u - 24 |
192 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 24
= 9 u - 24
9 u - 24 = 192
9 u = 192 + 24
9 u = 216
1 u = 216 ÷ 9 = 24
Number of mangosteens at first
= 4 u - 24 + 97
= 4 x 24 - 24 + 97
= 96 - 24 + 97
= 169
The number of chikoos and mangosteens at first was the same.
Number of chikoos sold
= 169 - 1 u
= 169 - 24
= 145
Answer(s): 145
