A fruit seller had the same number of peaches, grapefruits and chikoos at first. After 119 chikoos, some peaches and grapefruits were taken out, there were 169 fruits left. There were thrice as many peaches as grapefruits left. The number of chikoos left was 13 less than the number of peaches. How many grapefruits were taken out?

3 u |
1 u |
3 u - 13 |
169 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 13
= 7 u - 13
7 u - 13 = 169
7 u = 169 + 13
7 u = 182
1 u = 182 ÷ 7 = 26
Number of chikoos at first
= 3 u - 13 + 119
= 3 x 26 - 13 + 119
= 78 - 13 + 119
= 184
The number of grapefruits and chikoos at first was the same.
Number of grapefruits taken out
= 184 - 1 u
= 184 - 26
= 158
Answer(s): 158
