Zane had 70% fewer caramel apples than Cole. After Cole gave 400 caramel apples to Zane, Zane had ⁴₅ as many caramel apples as Cole. How many caramel apples did each of them have in the end?

1. Cole
2. Zane

	Zane	Cole	Total
Before	3x9 = 27 u	10x9 = 90 u	13x9 = 117 u
Change	+ 400	- 400
After	4x13 = 52 u	5x13 =  65 u	9x13 = 117 u

Number of caramel apples that Zane had at first in percentage
= 100% - 70%
= 30%

30% = ³⁰₁₀₀ = ³₁₀

The total number of caramel apples at first and in the end remains unchanged. Make the total number of caramel apples the same. LCM of 9 and 13 is 117.

Number of caramel apples that Cole gave to Zane
= 90 u - 65 u
= 25 u

25 u = 400

1 u = 400 ÷ 25 = 16

Number of caramel apples that Zane had in the end
= 52 u
= 52 x 16
= 832

Number of caramel apples that Cole had in the end
= 65 u
= 65 x 16
= 1040

Answer(s): (a) 832; (b) 1040
