Question

"10% of a solution of milk and water is removed and then replaced with the same amount of water. if the resulting ratio of milk and water is 2 : 3, find the ratio of milk and water in the original solution."

Answer 1

The ratio would be the same because water of same quantity is removed and the same is added
If correct mark me as the brainliest

Answer 2

Let's assume that the original solution contains 100 units of liquid (which could be milliliters, liters, etc.).

If we remove 10% of the solution, we will remove 10 units of liquid. The remaining 90 units of liquid will contain the same proportion of milk and water as the original solution.

Now, we replace the 10 units of liquid that we removed with the same amount of water. This means that the new solution contains 90 units of the original solution and 10 units of water.

The ratio of milk to water in the resulting solution is given as 2:3. This means that if we divide the 90 units of original solution into 5 equal parts (2 parts of milk and 3 parts of water), each part will be 18 units.

Therefore, the original solution contained 2 parts of milk and 3 parts of water out of a total of 5 parts. This means that the ratio of milk to water in the original solution is 2:3.
