It depends. If you mean you have left on the plate, that would be 3. If you mean in your stomach, that would be 1. If you mean somebody else came and ate another one, 2.

If you had 41 and now have 11 that means 30 were eaten. Now assuming you were fair and gave all your friends the same amount then you gave each friend 30/5 = 6 each. If you ate equally along with your friends then you all ate 30/6 = 5 each which means you gave away 5x5 = 25.
