Correct answer is 5 – You have 5 apples left
Since you own all five apples, taking away 3 from the 5 means you still have 5 apples. If the question said you gave out the 3 or ate the 3 apples then you have only two apples but since this isn’t stated, we assume the 3 apples are just put away in a separate place but you still own the five apples (2 apples left + 3 taken away). I believe this is the best approach to answering this question.
Hope this helps.

Why is not five? If you have five apples, like own it, andyoutake 3 of ourownedApples you'll still have five. Is it 3 because the apples were on the counter and you took 3 to carry on you or something?
