    1 Answer

    itีšs a simple logic there are 16 apples of different colours namely red, blue and green. So it is obvious that she has to take out all the 16 apples to make sure that that there is at least one apple of each colour (Red, Blue and Green) and no particular coloured apple is left behind. Take another example you have 6 button in your pocket (red, blue and green) in order to get a button of each colour so that no particular coloured button is left behind you must take out all the 6 buttons from your pocket.
