21. Question 21

    A milkman buys 20 litres of milk at Rs. 50 per litre. He adds mineral water costing Rs. 20 per litre, then sells the mixture at Rs. 60 per litre and makes a profit of Rs. 400. How much water did he add?

    1. A10 litres
    2. B8 litres
    3. C5 litres
    4. D4 litres

    Answer: (C) 5 litres

    Explanation

    Let x be the litres of water. Revenue is 60(20 + x), while cost is 1,000 + 20x; setting their difference to 400 gives 200 + 40x = 400, so x = 5. The selling price applies to the entire mixture.

23. Question 23

    The total monthly salary of a couple is Rs. 2.0 lakh. Their salaries are in the ratio 5:3. If the husband and wife spend 40% and 20% of their salaries respectively, what is the ratio of their savings?

    1. A3:2
    2. B5:3
    3. C5:4
    4. D3:1

    Answer: (C) 5:4

    Explanation

    Their savings are 60% of 5 parts and 80% of 3 parts: 3 parts and 2.4 parts. The ratio 3:2.4 simplifies to 5:4. The total salary cancels because only the ratio is required.
