A shopkeeper sells his goods at cost price but uses a faulty meter that weighs 800 grams. Find the profit percent.
Choose the correct option:
A) 100/17%	B) 100/23%	C) 100/19%	D) 100/4%	E) None of these
Explanation:   (100 + g) / (100 + x) = True measure / Faulty measure   x = 0   true measure = 1000   faulty measure = 800   100 + g / 100 + 0 = 1000 / 800   100+g = 5/4*100   g = 100/4 %   ANSWER: 100/4%
