The total number of mini cupcakes remains unchanged after Paul gives to Ryan.
Total number of mini cupcakes
= 361 + 592
= 953
Total number of mini cupcakes in the end
= 1 u + 1 u + 41
= 2 u + 41
2 u + 41 = 953
2 u = 953 - 41
2 u = 912
1 u = 912 ÷ 2 = 456
Number of mini cupcakes that Paul must give to Ryan
= 592 - 456
= 136
Answer(s): 136
