Each question below is followed by two statements I and II. You have to determine whether the data given in the statement is sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose the best possible answer. What is the profit percentage of a milkman? I. The milkman sells the milk at twice the Cost price of pure milk. II. He mixes 2 liters water with every 6 liters of pure milk.
Each question below is followed by two statements I and II. You have to determine whether the data given in the statement is sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose the best possible answer. What is the profit percentage of a milkman? I. The milkman sells the milk at twice the Cost price of pure milk. II. He mixes 2 liters water with every 6 liters of pure milk. Correct Answer If the data in either statement I alone or in statement II alone are sufficient to answer the question.
From statement I:
The selling price of the milk = 2 × Cost price of milk.
Profit % = (2x - x)/x × 100 = 100%
From statement II:
Let the C.P. of pure milk per liter be x.
8 liters of mixture = 2 liters of water + 6 liters of milk
Cost price of 8 liters of mixture = C.P. of 2 liter water + C.P. of 6 liter milk = 0 + 6x = 6x
From I, S.P. of 8 liter of mixture = S.P. of 8 liters of pure milk = 8 × x = 8x
Profit% = (8x - 6x)/6x × 100 = 33.33%
∴ The data in either statement I alone or in statement II alone are sufficient to answer the question.
