Why forces acts on two different bodies with same magnitude and opposite in direction doesn't cancel each other?
Because each force acts on a different body. If two equal and opposite forces act on the same body, then they do cancel.

This question is being asked very frequently. Is there any FAQ for this?

Let me give you an example. You and your friend are standing at opposite sides of a billiard table facing each other. Then you hit two balls simultaneously with equal and opposite forces. Do you expect that the two balls don't move?
