A shopkeeper sells his goods at cost price but uses a faulty meter that weighs 750 grams. Find the profit percent. | [
"100/23%",
"100/17%",
"100/19%",
"100/3%"
] | D | Explanation:
(100 + g) / (100 + x) = True measure / Faulty measure
x = 0
true measure = 1000
faulty measure = 750
100 + g / 100 + 0 = 1000 / 750
100+g = 4/3*100
g = 100/3 %
