• old as I was 4 years ago

⍖To Find

• The present age.

⍖Solution

Let, my present age be X years.

After 12 years my age will be (X + 12) years.

And 4 years ago my age was ( x - 4 ) years.

A. T. Q

∴ (x + 12) = 3(x-4)

⇛ x + 12 = 3x - 12

⇛ x = 12 years

Therefore, the present age is 12 years.
