Total |
| Before |
1 u - 21 |
1 u + 11 |
218 |
| Change |
+ 21 |
- 11 |
|
| After |
1 u |
1 u |
228 |
Total number of beads in the end
= 218 + 21 - 11
= 228
2 u = 228
1 u = 228 ÷ 2 = 114
Number of beads that Vincent had in the end
= 1 u
= 114
Number of beads that Vincent had at first
= 114 - 21
= 93
Answer(s): 93
