After |
3 u |
1 u |
3 u - 24 |
81 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 24
= 7 u - 24
7 u - 24 = 81
7 u = 81 + 24
7 u = 105
1 u = 105 ÷ 7 = 15
Number of mangoes at first
= 3 u - 24 + 62
= 3 x 15 + 38
= 83
The number of mangoes and guavas at first is the same.
Number of guavas sold
= 83 - 15
= 68
Answer(s): 68
