Fabian had 65% fewer mini cupcakes than Pierre. After Pierre gave 192 mini cupcakes to Fabian, Fabian had ³₄ as many mini cupcakes as Pierre. How many mini cupcakes did each of them have in the end?

1. Pierre
2. Fabian

	Fabian	Pierre	Total
Before	7x7 = 49 u	20x7 = 140 u	27x7 = 189 u
Change	+ 192	- 192
After	3x27 = 81 u	4x27 =  108 u	7x27 = 189 u

Number of mini cupcakes that Fabian 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 7 and 27 is 189.

Number of mini cupcakes that Pierre gave to Fabian
= 140 u - 108 u
= 32 u

32 u = 192

1 u = 192 ÷ 32 = 6

Number of mini cupcakes that Fabian had in the end
= 81 u
= 81 x 6
= 486

Number of mini cupcakes that Pierre had in the end
= 108 u
= 108 x 6
= 648

Answer(s): (a) 486; (b) 648
