- 3x12 =
- 36 u |

After |
35 u |
2x12 =
24 u |
472 |
The number of apples at first is repeated. Make the number of apples at first the same. LCM of 12 and 5 is 60.
Total number of fruits left
= 35 u + 24 u
= 59 u
59 u = 472
1 u = 472 ÷ 59 = 8
Number of fruits at first
= 35 u + 60 u
= 95 u
= 95 x 8
= 760
Answer(s): 760
