Based on the given information, Helen is 26 years old.

Let's represent Helen's age as x.

According to the given information, John is twice as old as Helen, so John's age can be represented as 2x.

Subtracting 4 from John's age and then dividing by 2 gives William's age. So, William's age is (2x - 4)/2 = x - 2.

Given that William's age is 24, we can set up the equation x - 2 = 24 and solve for x.

Adding 2 to both sides of the equation, we get x = 26.

Therefore, Helen is 26 years old.
