if w is 40 percent less than q , q is 40 percent less than y , and z is 46 percent less than y , then z is greater than w by what percent of w ?
given w = 0.6 q , q = 0.6 y , z = 0.54 y , substituting , w = 2 / 3 z - - - - > z = 1.5 w and thus z is 50 % greater than w . e is the correct answer .
multiply(divide(subtract(subtract(const_100, 46), subtract(subtract(const_100, 40), divide(multiply(40, subtract(const_100, 40)), const_100))), subtract(subtract(const_100, 40), divide(multiply(40, subtract(const_100, 40)), const_100))), const_100)
