Sam had 75% fewer mini cupcakes than Zane. After Zane gave 190 mini cupcakes to Sam, Sam had ²₃ as many mini cupcakes as Zane. How many mini cupcakes did each of them have in the end?

1. Zane
2. Sam

	Sam	Zane	Total
Before	1x5 = 5 u	4x5 = 20 u	5x5 = 25 u
Change	+ 190	- 190
After	2x5 = 10 u	3x5 =  15 u	5x5 = 25 u

Number of mini cupcakes that Sam 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 5 and 5 is 25.

Number of mini cupcakes that Zane gave to Sam
= 20 u - 15 u
= 5 u

5 u = 190

1 u = 190 ÷ 5 = 38

Number of mini cupcakes that Sam had in the end
= 10 u
= 10 x 38
= 380

Number of mini cupcakes that Zane had in the end
= 15 u
= 15 x 38
= 570

Answer(s): (a) 380; (b) 570
