A store owner had the same number of mangoes, chikoos and grapefruits at first. After 53 grapefruits, some mangoes and chikoos were sold, there were 191 fruits left. There were four times as many mangoes as chikoos left. The number of grapefruits left was 25 less than the number of mangoes. How many chikoos were sold?

4 u |
1 u |
4 u - 25 |
191 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 25
= 9 u - 25
9 u - 25 = 191
9 u = 191 + 25
9 u = 216
1 u = 216 ÷ 9 = 24
Number of grapefruits at first
= 4 u - 25 + 53
= 4 x 24 - 25 + 53
= 96 - 25 + 53
= 124
The number of chikoos and grapefruits at first was the same.
Number of chikoos sold
= 124 - 1 u
= 124 - 24
= 100
Answer(s): 100
