Strength of first jar Strength of 2nd jar
40% Mean
Strength
26% 		19%
7 14

So, ratio of 1st and 2nd quantities = 7 : 14 = 1 : 2

Ya. I too confused with the result as 2/3. Can any one explain how we will get 2/3?

So, how much quantity of whisky in % is replaced? Should we consider 2/3 * 100%?
Maggi said:   1 decade ago
Why not 1/3. Because in question it is asked the replaced whisky of 1st jar.
