Hi friend ✋✋✋✋
--------------
Your answer
--------------------

Let my present age be x.

Then, my sister's age = (x - 8) .

Then,
-----------
According to the question,
----------------------------------------

(x - 8) - 4 = x/2

=> x - 8 - 4 = x/2

=> x - 12 = x/2

=> 2(x - 12) = x

=> 2x - 24 = x

=> 2x - x = 24

=> x = 24

Therefore,
-----------------

My age = x = 24 years

My sister's age = (x - 8) = (24 - 8) years = 16 years
