  • Question
  • A shopkeeper buys 26 liter of milk @ Rs. 16 per liter. He also buys from another source an inferior quality of milk @ Rs. 10 per liter. How much quantity of the later should he buy to mix it with the former so that he can sell the mixture @ Rs. 14 per liter without making any loss?


  • Options
  • A. 13 liter
  • B. 12 liter
  • C. 14 liter
  • D. 16 liter

  • Correct Answer
  • 13 liter 

    Explanation

    Quantity of milk @ Rs.10 per liter / Quantity of milk @ Rs. 16 per liter = 1 / 2
    So, quantity of milk @ Rs. 10 per liter = 26 / 2 = 13 liter.

    2nd Method
    Let us assume shopkeeper buy P liter milk of price @ Rs. 10 per liter.
    Buy price of 26 liter of milk @ Rs. 16 per liter = 26 x 16
    Buy price of P liter of milk @ Rs. 10 per liter = P x 10
    Sell price of total milk ( P + 26 ) @ Rs. 14 per liter = 14 x ( P + 26 )
    According to question there is no loss or no profit.
    Then Buy Price = Sell Price
    26 x 16 + P x 10 = 14 x ( P + 26 )
    ? 26 x 16 + 10P = 14P + 14 x 26
    ? 26 x 16 - 26 x 14 = 14P - 10P
    ? 2 x 26 = 4P
    ? 4P = 2 x 26
    ? P = 2 x 26 / 4 = 13

    So, quantity of milk @ Rs. 10 per liter = 13 liter.
