Question

The price of pure milk per litre is Rs. 2.50. At what ratio the water is to be mixed with pure milk and sold the mixture at Rs. 2 per litre on no profit no loss basis.​

Answer 1

Answer:

The ratio of pure milk is to water should be 4 : 1

Step-by-step explanation:

Let the amount of pure milk is 'a' litre and 'b' litre water is added to sell the mixture at Rs.2 Per litre.

So, total cost of pure milk (cost price) = 2.50 a

total selling price of the mixture = 2 (a+b)

Since there is no profit no loss, so total selling price = total cost price

therefore, 2.50 a = 2 (a+b)

  => 2.50 a = 2a + 2b

=> 2.50 a - 2a = 2b

=> 0.50 a = 2b

therefore a/b = 2/0.5 = 4/1

Therefore a: b = 4:1

So, the ratio of pure milk is to water should be 4 : 1
