- 3x9 =
- 27 u |

After |
16 u |
1x9 =
9 u |
200 |
The number of apricots at first is repeated. Make the number of apricots at first the same. LCM of 9 and 4 is 36.
Total number of fruits left
= 16 u + 9 u
= 25 u
25 u = 200
1 u = 200 ÷ 25 = 8
Number of fruits at first
= 16 u + 36 u
= 52 u
= 52 x 8
= 416
Answer(s): 416
