A brown flask contains a concoction that is 20% alcohol. A red flask contains a concoction with an unknown amount of alcohol. An equal amount of both flasks is poured into an empty jug. If the resulting mixture has an alcohol concentration that is 30% greater than the alcohol concentration of the brown flask, what percent alcohol did the red flask originally contain?

Have you made an attempt at the question? Maybe start with the fact that your final concentration is 30% greater than 20%. You can also think of that as being 130% of 20%. What would that be?
What does "30% greater than the alcohol concentration" mean?
Does it mean that in the same amount of concoction, there is 30% more alcohol, or does it mean the concentration is 30 percentage points higher?
