At first, Lee, Winnie and Mark had some caramel apples in the ratio 7 : 5 : 6 respectively. Lee had 336 caramel apples. Then he gave all his caramel apples to Winnie and Mark. After receiving the caramel apples from Lee, Winnie and Mark had the same number of caramel apples. How many caramel apples did Winnie receive from Lee?

	Lee	Winnie	Mark	Total
Before	7x1 = 7 u	5x1 = 5 u	6x1 = 6 u	18x1 = 18 u
Change	- 7 u	+ 7 u
After	0	1x9 = 9 u	1x9 = 9 u	2x9 = 18 u

The total number of caramel apples remains unchanged. Make the total number of caramel apples the same.  LCM of 2 and 18 is 18.

Total number of caramel apples = 18 u

Number of caramel apples that Winnie had in the end 
= 18 u ÷ 2
= 9 u

Number of caramel apples that Lee had at first = 7 u 

7 u = 336

1 u = 336 ÷ 7 = 48

Number of caramel apples that Winnie received from Lee
= 9 u - 5 u
= 4 u
= 4 x 48
= 192

Answer(s): 192
