a shopkeeper sells his goods at cost price but uses a faulty meter that weighs 940 grams . find the profit percent .
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 : d
multiply(divide(subtract(multiply(add(add(const_4, const_1), add(const_4, const_1)), const_100), 940), 940), const_100)
