- 4x12 =
- 48 u |

After |
35 u |
1x12 =
12 u |
235 |
The number of limes at first is repeated. Make the number of limes at first the same. LCM of 12 and 5 is 60.
Total number of fruits left
= 35 u + 12 u
= 47 u
47 u = 235
1 u = 235 ÷ 47 = 5
Number of fruits at first
= 35 u + 60 u
= 95 u
= 95 x 5
= 475
Answer(s): 475
