Warren had 60% fewer candy canes than Justin. After Justin gave 210 candy canes to Warren, Warren had ³₄ as many candy canes as Justin. How many candy canes did each of them have in the end?

1. Justin
2. Warren

	Warren	Justin	Total
Before	2x7 = 14 u	5x7 = 35 u	7x7 = 49 u
Change	+ 210	- 210
After	3x7 = 21 u	4x7 =  28 u	7x7 = 49 u

Number of candy canes that Warren had at first in percentage
= 100% - 60%
= 40%

40% = ⁴⁰₁₀₀ = ²₅

The total number of candy canes at first and in the end remains unchanged. Make the total number of candy canes the same. LCM of 7 and 7 is 49.

Number of candy canes that Justin gave to Warren
= 35 u - 28 u
= 7 u

7 u = 210

1 u = 210 ÷ 7 = 30

Number of candy canes that Warren had in the end
= 21 u
= 21 x 30
= 630

Number of candy canes that Justin had in the end
= 28 u
= 28 x 30
= 840

Answer(s): (a) 630; (b) 840
