Paul had some pastries.
47 of them were shortbreads. The rest were tarts. He sold

3x4 =
12 u |
15 u - 6 |
The number of shortbreads at first is repeated. Make the number of shortbreads at first the same. LCM of 4 and 5 is 20.
Total number of pastries left
= 12 u + 15 u - 6
= 27 u - 6
27 u - 6 = 183
27 u = 183 + 6
27 u = 189
1 u = 189 ÷ 27 = 7
Number of more shortbreads than tarts that Paul sold
= 8 u - 6
= 8 x 7 - 6
= 56 - 6
= 50
Answer(s): 50
