A grocer had the same number of chikoos, mangoes and persimmons at first. After 127 persimmons, some chikoos and mangoes were sold, there were 136 fruits left. There were thrice as many chikoos as mangoes left. The number of persimmons left was 39 less than the number of chikoos. How many mangoes were sold?

3 u |
1 u |
3 u - 39 |
136 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 39
= 7 u - 39
7 u - 39 = 136
7 u = 136 + 39
7 u = 175
1 u = 175 ÷ 7 = 25
Number of persimmons at first
= 3 u - 39 + 127
= 3 x 25 - 39 + 127
= 75 - 39 + 127
= 163
The number of mangoes and persimmons at first was the same.
Number of mangoes sold
= 163 - 1 u
= 163 - 25
= 138
Answer(s): 138
