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 $$Y=2X$$

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

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