if w is 40 percent less than u , u 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 u , u = 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 .
subtract(divide(const_1, divide(divide(multiply(subtract(const_1, divide(40, const_100)), subtract(const_1, divide(40, const_100))), subtract(const_1, divide(46, const_100))), const_100)), const_100)
