Wesley had a total of 110 lemons and persimmons. He sold
13 of the persimmons and bought another 25 lemons. In the end, the number of lemons he had was

The number of persimmons in the end is repeated. Make the number of persimmons in the end the same. LCM of 2 and 4 is 4.
Total number of lemons and persimmons at first
= 3 u - 25 + 6 u
= 9 u - 25
9 u - 25 = 110
9 u = 110 + 25
9 u = 135
1 u = 135 ÷ 9 = 15
Number of more persimmons than lemons at first
= 6 u - (3 u - 25)
= 6 u - 3 u + 25
= 3 u + 25
= 3 x 15 + 25
= 45 + 25
= 70
Answer(s): 70
