Given the information in the question, Paul's current age is 8 years old. You can work this out by using an algebra type equation to understand each stage of the questions and come to a reasonable conclusion.
Below is the equation that was used to work out the age of Paul at present.
X - 4 = 3Y (Paul's age minus the 4 years)
X = 6Y (Paul's age is equal to 6 times that of Alice)
X = 6Y + 2 (X - 4) =6Y
Therefore X = 2 (X - 4)
X = 2X - 8
-X = -8
Therefore X = 8. This gives us the answer that Paul ( X ) is 8 years old at present.

- How to find the answer
X - 4 = 3Y (Paul's age minus the 4 years)
X = 6Y (Paul's age is equal to 6 times that of Alice)
X = 6Y + 2 (X - 4) =6Y
Therefore X = 2 (X - 4)
X = 2X - 8
-X = -8
Therefore X = 8. This gives us the answer that Paul ( X ) is 8 years old at present.
