A grocer had the same number of pears, chikoos and grapefruits at first. After 95 grapefruits, some pears and chikoos were used, there were 174 fruits left. There were five times as many pears as chikoos left. The number of grapefruits left was 13 fewer than the number of pears. How many chikoos were used?

5 u |
1 u |
5 u - 13 |
174 |
Total number of fruits in the end
= 5 u + 1 u + 5 u - 13
= 11 u - 13
11 u - 13 = 174
11 u = 174 + 13
11 u = 187
1 u = 187 ÷ 11 = 17
Number of grapefruits at first
= 5 u - 13 + 95
= 5 x 17 - 13 + 95
= 85 - 13 + 95
= 167
The number of chikoos and grapefruits at first was the same.
Number of chikoos used
= 167 - 1 u
= 167 - 17
= 150
Answer(s): 150
