- 2x12 =
- 24 u |

After |
35 u |
3x12 =
36 u |
355 |
The number of lemons at first is repeated. Make the number of lemons at first the same. LCM of 12 and 5 is 60.
Total number of fruits left
= 35 u + 36 u
= 71 u
71 u = 355
1 u = 355 ÷ 71 = 5
Number of fruits at first
= 35 u + 60 u
= 95 u
= 95 x 5
= 475
Answer(s): 475
