Directions: In the following question, you have to find out the redundant statement(s) for determining the answer to the given question. A food processing unit sells a homogeneous mixture of low fat milk and high fat milk at the rate of Rs. 50 per kg. What is the profit earned by the unit? I. It buys low fat milk at the rate of Rs. 30 per kg. II. It buys per kg of high fat milk for Rs. 10 more than per kg of low fat milk. III. It buys high fat milk at the rate of Rs. 40 per kg.

To find the profit, we must know the exact cost price of the mixture per kg. We are given the selling price of the mixture is Rs. 50 per kg, and statements I and III give the cost of low fat and high fat milk as Rs. 30 and Rs. 40 per kg respectively. However, none of the statements provide the ratio in which the two types of milk are mixed to create the homogeneous mixture. Without the mixing ratio, the overall cost price cannot be determined, meaning all statements together are not sufficient.
