Total amount at first = $280 X 2 = $560
Total amount at the end = $560 - $83 + $48 = $525

5 units = $525
1 unit = $525/5 = $105

Amount Benny had at first = $105 + $83 = $188
Amount Hashim had at first = ($105 X 4) - $48 = $420 - $48 = $372

Difference between Benny and Hashim at first = $372 - $188 = $184
