Question

After 14 years, I shall be three times as old as I was 4 years ago. My present age is

Answer 1

Answer:

13 years.

Step-by-step explanation:

Let my present age = $x$

4 years ago, my age = $x-4$

After 14 years, my age = $x+14$

Now, as per the question, $x+14 = 3*(x-4)$

⇒ $x+14= 3x - 3*4$

⇒ $x+14= 3x - 12$

⇒ $x+14+12 = 3x$

⇒ $x+26 = 3x$

⇒ $26 = 3x - x$

⇒ $26 = 2x$

⇒ $\frac{26}{2} = x$

⇒ $x = 13$

Answer: ∴ My present age is 13 years.
