Luis had 60% fewer chocolate bars than Wesley. After Wesley gave 364 chocolate bars to Luis, Luis had ³₄ as many chocolate bars as Wesley. How many chocolate bars did each of them have in the end?

1. Wesley
2. Luis

	Luis	Wesley	Total
Before	2x7 = 14 u	5x7 = 35 u	7x7 = 49 u
Change	+ 364	- 364
After	3x7 = 21 u	4x7 =  28 u	7x7 = 49 u

Number of chocolate bars that Luis had at first in percentage
= 100% - 60%
= 40%

40% = ⁴⁰₁₀₀ = ²₅

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

Number of chocolate bars that Wesley gave to Luis
= 35 u - 28 u
= 7 u

7 u = 364

1 u = 364 ÷ 7 = 52

Number of chocolate bars that Luis had in the end
= 21 u
= 21 x 52
= 1092

Number of chocolate bars that Wesley had in the end
= 28 u
= 28 x 52
= 1456

Answer(s): (a) 1092; (b) 1456
