- 5x1 =

- 10 |
After

1x1 =
1 u |
8 u - 10 |
The number of macarons at first is repeated. Make the number of macarons at first the same. LCM of 3 and 6 is 6.
Total number of pastries left
= 1 u + 8 u - 10
= 9 u - 10
9 u - 10 = 35
9 u = 35 + 10
9 u = 45
1 u = 45 ÷ 9 = 5
Number of more macarons than biscuits that Zeph sold
= 5 u - 10
= 5 x 5 - 10
= 25 - 10
= 15
Answer(s): 15
