60 liters of first mixture of milk and water is mixed with another 40 liters mixture of milk and water. After mixing the mixture, the mixture is sold at the cost of pure milk, then what is the percent profit gained if the ratio of milk to water in the first and second mixture is 7: 5 and 3: 5, respectively? Given below are the steps involved. Arrange them in sequential order.
(A) Amount of milk and water in first mixture is 60 x (7/12) = 35 liters and 60 x (5/12) = 25 liters respectively.
(B) Total amount of milk and water is final mixture is (35 + 15) = 50 liters and (25 + 25) = 50 liters respectively.
(C) Percent profit earned = [(100 - 50)/50] x 100 = 100%
(D) Amount of milk and water in second mixture is 40 x (3/8) = 15 liters and 40 x (5/8) = 25 litres respectively.
(E) Cost price of final mixture = 50 x 1 = 50 and selling price of final mixture = 100 x 1 = 100
