Question

How many litres of water must be added to 10 litres of milk costing 12 per litre, so that on selling the mixture at 12.50 per litre, 25% profit is mad

Answer 1

If Selling Price of the mixture is ₹ 12.50 with a profit of 25% then,

CP = 1250/125 =₹10/l

CP of pure milk(without adding water) = ₹12per litre.

Now we have to find the ratio between the pure milk : mixture (water&milk) : water

We get,

12:12.50 (at 25% interest):X
