20 years from now a person will be 3 times as old as he is now how old is he now

To determine the person's current age, we can set up an equation using the information given.

Let's assume the person's current age is represented by "x" years. After 20 years, the person will be "x + 20" years old.

According to the information given, in 20 years, the person will be three times as old as they are now. This can be expressed as:

(x + 20) = 3x

Now we can solve the equation to find the person's current age:

x + 20 = 3x
20 = 3x - x
20 = 2x
x = 20/2
x = 10

Therefore, the person is currently 10 years old.
