Fred had 60% fewer mini cupcakes than John. After John gave 371 mini cupcakes to Fred, Fred had ³₄ as many mini cupcakes as John. How many mini cupcakes did each of them have in the end?

1. John
2. Fred

	Fred	John	Total
Before	2x7 = 14 u	5x7 = 35 u	7x7 = 49 u
Change	+ 371	- 371
After	3x7 = 21 u	4x7 =  28 u	7x7 = 49 u

Number of mini cupcakes that Fred had at first in percentage
= 100% - 60%
= 40%

40% = ⁴⁰₁₀₀ = ²₅

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 7 is 49.

Number of mini cupcakes that John gave to Fred
= 35 u - 28 u
= 7 u

7 u = 371

1 u = 371 ÷ 7 = 53

Number of mini cupcakes that Fred had in the end
= 21 u
= 21 x 53
= 1113

Number of mini cupcakes that John had in the end
= 28 u
= 28 x 53
= 1484

Answer(s): (a) 1113; (b) 1484
