2 u |
1 u |
2 u - 19 |
126 |
Total number of fruits in the end
= 2 u + 1 u + 2 u - 19
= 5 u - 19
5 u - 19 = 126
5 u = 126 + 19
5 u = 145
1 u = 145 ÷ 5 = 29
Number of pears at first
= 2 u - 19 + 40
= 2 x 29 + 21
= 79
The number of pears and lemons at first is the same.
Number of lemons sold
= 79 - 29
= 50
Answer(s): 50
