Question

After 12 year i shall be 3 times as old as i was 4 years ago find present age

Answer 1

Present age =4 years

Answer 2

Let the present age be x.


After 12 years:

My age will be x + 12.

4 years Ago:

My age will be x - 4.


Given that After 12 years I shall be 3 times as old as I was 4 years ago.

x + 12 = 3(x - 4)

x + 12 = 3x - 12

x + 12 + 12 = 3x

x + 24 = 3x

24 = 3x - x

24 = 2x

x = 12 years.

Therefore my present age = 12 years.


Hope this helps!
