A shopkeeper sells his goods at cost price but uses a faulty meter that weighs 940 grams. Find the profit percent. Choose the correct choice.
A) 7.38	B) 5.38	C) 4.38	D) 6.38	E) 3.38
Explanation:   (100 + g) / (100 + x) = True measure / Faulty measure   x = 0   true measure = 1000   faulty measure = 940   100 + g / 100 + 0 = 1000 / 940   100+g = 100/94*100   g = 6.38   ANSWER: 6.38
