Ian had 75% fewer chocolate bars than Wesley. After Wesley gave 392 chocolate bars to Ian, Ian had ⁵₆ as many chocolate bars as Wesley. How many chocolate bars did each of them have in the end?

1. Wesley
2. Ian

	Ian	Wesley	Total
Before	1x11 = 11 u	4x11 = 44 u	5x11 = 55 u
Change	+ 392	- 392
After	5x5 = 25 u	6x5 =  30 u	11x5 = 55 u

Number of chocolate bars that Ian had at first in percentage
= 100% - 75%
= 25%

25% = ²⁵₁₀₀ = ¹₄

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 11 and 5 is 55.

Number of chocolate bars that Wesley gave to Ian
= 44 u - 30 u
= 14 u

14 u = 392

1 u = 392 ÷ 14 = 28

Number of chocolate bars that Ian had in the end
= 25 u
= 25 x 28
= 700

Number of chocolate bars that Wesley had in the end
= 30 u
= 30 x 28
= 840

Answer(s): (a) 700; (b) 840
