Flynn had 65% fewer mini cupcakes than Mark. After Mark gave 323 mini cupcakes to Flynn, Flynn had ²₃ as many mini cupcakes as Mark. How many mini cupcakes did each of them have in the end?

1. Mark
2. Flynn

	Flynn	Mark	Total
Before	7x5 = 35 u	20x5 = 100 u	27x5 = 135 u
Change	+ 323	- 323
After	2x27 = 54 u	3x27 =  81 u	5x27 = 135 u

Number of mini cupcakes that Flynn had at first in percentage
= 100% - 65%
= 35%

35% = ³⁵₁₀₀ = ⁷₂₀

The total number of mini cupcakes at first and in the end remains unchanged. Make the total number of mini cupcakes the same. LCM of 5 and 27 is 135.

Number of mini cupcakes that Mark gave to Flynn
= 100 u - 81 u
= 19 u

19 u = 323

1 u = 323 ÷ 19 = 17

Number of mini cupcakes that Flynn had in the end
= 54 u
= 54 x 17
= 918

Number of mini cupcakes that Mark had in the end
= 81 u
= 81 x 17
= 1377

Answer(s): (a) 918; (b) 1377
