A grocer had the same number of pomegranates, guavas and peaches at first. After 115 peaches, some pomegranates and guavas were sold, there were 139 fruits left. There were four times as many pomegranates as guavas left. The number of peaches left was 14 less than the number of pomegranates. How many guavas were sold?

1 u |
4 u - 14 |
139 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 14
= 9 u - 14
9 u - 14 = 139
9 u = 139 + 14
9 u = 153
1 u = 153 ÷ 9 = 17
Number of peaches at first
= 4 u - 14 + 115
= 4 x 17 - 14 + 115
= 68 - 14 + 115
= 169
The number of guavas and peaches at first was the same.
Number of guavas sold
= 169 - 1 u
= 169 - 17
= 152
Answer(s): 152
