After |
3 u |
1 u |
3 u - 26 |
100 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 26
= 7 u - 26
7 u - 26 = 100
7 u = 100 + 26
7 u = 126
1 u = 126 ÷ 7 = 18
Number of mangoes at first
= 3 u - 26 + 40
= 3 x 18 + 14
= 68
The number of mangoes and pears at first is the same.
Number of pears sold
= 68 - 18
= 50
Answer(s): 50
