and lemons at first |
7x5 =
35 u |
12x5 =
60 u |
95 u |
Before |

5x12 =
60 u |

- 2x12 =
- 24 u |
|
After |
35 u |
3x12 =
36 u |
284 |
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 = 284
1 u = 284 ÷ 71 = 4
Number of fruits at first
= 35 u + 60 u
= 95 u
= 95 x 4
= 380
Answer(s): 380
