- 3x9 =
- 27 u |

After |
10 u |
2x9 =
18 u |
84 |
The number of apricots at first is repeated. Make the number of apricots at first the same. LCM of 9 and 5 is 45.
Total number of fruits left
= 10 u + 18 u
= 28 u
28 u = 84
1 u = 84 ÷ 28 = 3
Number of fruits at first
= 10 u + 45 u
= 55 u
= 55 x 3
= 165
Answer(s): 165
