I solved in this way. I hope I am going in the right direction.

Let Volume of Drum X = X
Then Current oil in X = \(\frac{1}{2}\)X

Let Volume of Drum Y = Y
Then Current Oil in Y = \(\frac{2}{3}\)Y

Also Y=2X

Now the statement says oil from X is poured in Y

Hence find the total volume of oil WRT Y

\([\frac{1}{2}X+\frac{2}{3}Y)/Y\)

Replacing \(Y=2X\)

\([\frac{1}{2}X+(\frac{2}{3}*2X)]/(2X)\)

= \([\frac{11}{6}X]/(2X)\) = \(\frac{11}{12}X\)
