Two vessels having volumes in the ratio 3:5 are filled with water and ...
Let the volumes of the two vessels be 3x and 5x, where x is a common factor.
The first vessel contains a milk and water solution in the ratio 2:3.
This means that for every 2 units of milk, there are 3 units of water.
Therefore, the first vessel contains (2/5) * 3x = (6/5)x units of milk and (3/5) * 3x = (9/5)x units of water.
Similarly, the second vessel contains a milk and water solution in the ratio 3:1.
This means that for every 3 units of milk, there is 1 unit of water.
So, the second vessel contains (3/4) * 5x = (15/4)x units of milk and (1/4) * 5x = (5/4)x units of water.
Now, when we combine the contents of both vessels into a larger vessel, we add up the amounts of milk and water from each vessel.
The total amount of milk in the larger vessel is (6/5)x + (15/4)x = (48x + 75x)/(20) = (123x)/(20).
Similarly, the total amount of water in the larger vessel is (9/5)x + (5/4)x = (36x + 25x)/(20) = (61x)/(20).
Therefore, the ratio of milk to water in the larger vessel is (123x)/(20) : (61x)/(20).
To simplify this ratio, we can divide both terms by x, as x is a common factor:
Ratio = 123 : 61
This means that the ratio of milk to water in the larger vessel is 123:61.
Comparing this with the answer choices provided, we can see that the correct answer is indeed A) 99:61.
