at first |
4x3 =
12 u |
3x3 =
9 u |
Before

6x2 =
12 u |
9 u |

- 5x2 =
- 10 u |
- 5 |
After

1x2 =
2 u |
9 u - 5 |
The number of macarons at first is repeated. Make the number of macarons at first the same. LCM of 4 and 6 is 12.
Total number of pastries left
= 2 u + 9 u - 5
= 11 u - 5
11 u - 5 = 94
11 u = 94 + 5
11 u = 99
1 u = 99 ÷ 11 = 9
Number of more macarons than wafers that George sold
= 10 u - 5
= 10 x 9 - 5
= 90 - 5
= 85
Answer(s): 85
