7x5 =
35 u |
12x5 =
60 u |
95 u |
Before |

5x12 =
60 u |

- 4x12 =
- 48 u |

After |
35 u |
1x12 =
12 u |
94 |
The number of peaches at first is repeated. Make the number of peaches at first the same. LCM of 12 and 5 is 60.
Total number of fruits left
= 35 u + 12 u
= 47 u
47 u = 94
1 u = 94 ÷ 47 = 2
Number of fruits at first
= 35 u + 60 u
= 95 u
= 95 x 2
= 190
Answer(s): 190
