4x3 =

- 5x2 =

After

1x2 =
2 u |
9 u - 3 |
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 - 3
= 11 u - 3
11 u - 3 = 63
11 u = 63 + 3
11 u = 66
1 u = 66 ÷ 11 = 6
Number of more macarons than shortbreads that Vaidev sold
= 10 u - 3
= 10 x 6 - 3
= 60 - 3
= 57
Answer(s): 57
