At first, Neave, Tiffany and Xavier had some caramel apples in the ratio 5 : 3 : 4 respectively. Neave had 425 caramel apples. Then he gave all his caramel apples to Tiffany and Xavier. After receiving the caramel apples from Neave, Tiffany and Xavier had the same number of caramel apples. How many caramel apples did Tiffany receive from Neave?

	Neave	Tiffany	Xavier	Total
Before	5x1 = 5 u	3x1 = 3 u	4x1 = 4 u	12x1 = 12 u
Change	- 5 u	+ 5 u
After	0	1x6 = 6 u	1x6 = 6 u	2x6 = 12 u

The total number of caramel apples remains unchanged. Make the total number of caramel apples the same.  LCM of 2 and 12 is 12.

Total number of caramel apples = 12 u

Number of caramel apples that Tiffany had in the end 
= 12 u ÷ 2
= 6 u

Number of caramel apples that Neave had at first = 5 u 

5 u = 425

1 u = 425 ÷ 5 = 85

Number of caramel apples that Tiffany received from Neave
= 6 u - 3 u
= 3 u
= 3 x 85
= 255

Answer(s): 255
