A dishonest milkman purchased milk at Rs. 66 per liter and mixes 9 liter water in it. He sold the mixture at Rs. 66 per liter and still he gains 33.33% profit. Find the quantity of milk bought by him.
Answer & explanation
Correct answer: option 1
33.33% profit ⇒ \(\frac{1}{3}\) = \(\frac{Water\;Qyt}{Milk\;Qty}\)
{***it is only applicable when mixture is sold at the cost price of milk}
Milk : Water ⇒ total mixture
Qty: 3 : 1 ⇒ 4
1R = 9 liter
Milk= 3R = 3 × 9 = 27
