The jars contain milk and water in the ratio 2:1 and 3:2 respectively.

In percentages,
Jar 1 contains (2/3)*100 = 66.66% milk
Jar 2 contains (3/5)*100 = 60% milk

The required ratio is 1:1 which is equivalent to (1/2)*100 = 50% milk

Now, we know that while mixing two solutions, the final milk percentage should lie between the percentages of milk in initial solutions, ie Jar 1 and Jar 2.

Thus we can easily choose option (5)
