- 2x10 =
- 20 u |

After |
9 u |
1x10 =

The number of mangosteens at first is repeated. Make the number of mangosteens at first the same. LCM of 10 and 3 is 30.
Total number of fruits left
= 9 u + 10 u
= 19 u
19 u = 228
1 u = 228 ÷ 19 = 12
Number of fruits at first
= 9 u + 30 u
= 39 u
= 39 x 12
= 468
Answer(s): 468
