a shopkeeper forced to sell at cost price , uses a 750 grams weight for a kilogram . what is his gain percent ?
shopkeeper sells 750 g instead of 1000 g . so , his gain = 1000 - 750 = 250 g . thus , % gain = ( 250 * 100 ) / 750 = 33.33 % . answer : option c
multiply(divide(add(multiply(const_2, const_100), divide(const_100, const_2)), 750), const_100)
