## CORRECT ANSWER:

Let us suppose two years ago Alex was “X” years

Then, Dana was 3X

Three years from now, Alex will be (X +2+3) = (X+5) years

And Dana will be (3X+2+3) = (3X+5) years

But it is given that Dana will be twice as old as Alex.

So, 2(X+5)= (3X+5)

or, X= 5 years

**So Alex is 5+2= 7 years**

**And Dana is 5*3+2= 17 years**
