Valen had 75% fewer mini cupcakes than Perry. After Perry gave 378 mini cupcakes to Valen, Valen had ⁵₆ as many mini cupcakes as Perry. How many mini cupcakes did each of them have in the end?

1. Perry
2. Valen

	Valen	Perry	Total
Before	1x11 = 11 u	4x11 = 44 u	5x11 = 55 u
Change	+ 378	- 378
After	5x5 = 25 u	6x5 =  30 u	11x5 = 55 u

Number of mini cupcakes that Valen had at first in percentage
= 100% - 75%
= 25%

25% = ²⁵₁₀₀ = ¹₄

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 11 and 5 is 55.

Number of mini cupcakes that Perry gave to Valen
= 44 u - 30 u
= 14 u

14 u = 378

1 u = 378 ÷ 14 = 27

Number of mini cupcakes that Valen had in the end
= 25 u
= 25 x 27
= 675

Number of mini cupcakes that Perry had in the end
= 30 u
= 30 x 27
= 810

Answer(s): (a) 675; (b) 810
