solution x is 30 % chemical a and 70 % chemical b by volume . solution y is 40 % chemical a and 60 % chemical b by volume . if a mixture of x and y is 32 % chemical a , what percent of the mixture is solution x ?
the volume of the mixture be x + y . 0.3 x + 0.4 y = 0.32 ( x + y ) x = 4 y x / ( x + y ) = 4 / 5 = 80 % . the answer is b .
multiply(divide(divide(subtract(40, 32), subtract(32, 30)), add(divide(subtract(40, 32), subtract(32, 30)), const_1)), const_100)
