  • Question
  • A milk merchant buys 50 litres of milk at the rate of Rs 40 per litre and mixes 5 litres of water in it. If he sells this mixture at the rate of Rs 42 per litre, then what is the profit percentage for the dealer?


  • Options
  • A. 17.2
  • B. 14.4
  • C. 16.6
  • D. 15.5

  • Correct Answer
  • 15.5 

    Explanation

    Number of liters of water in 150 liters of the mixture = 20% of 150 = 20/100 x 150 = 30 liters.
    P liters of water added to the mixture to make water 25% of the new mixture.
    Total amount of water becomes (30 + P) and total volume of mixture is (150 + P).
    (30 + P) = 25/100 x (150 + P)
    120 + 4P = 150 + P => P = 10 liters.
