How Old Will I be 3 Years From Now?

How old am I

Answer

Let x be my present age. My age 3 years from now will be x + 3, and 3 times that will be 3 (x + 3). Similarly, my age 4 years from now will be x + 4, and 4 times that will be 4 (x + 4).

Adding the two gives 8 times my current age. This gives the equation:

3 (x + 3) + 4 (x + 4) = 8 x.

Solving the above equation gives

x = (3 × 3) + (4 × 4) = 25.

therefore in 3 years I will be 28.
