There are 21 juice bottles out of which 7 bottles are full, 7 are half-full and the remaining 7 are empty to be divided amongst 3 friends equally. You don’t have any measuring device. How will you divide them (both bottles and juice) equally?
Answer: Each friend will get 3 full bottles of juice, 3 empty bottles and 1 half filled bottle.
Explanation: Empty 2 half filled bottles into one empty bottle. Again empty 2 half filled bottles into one empty bottle. So now you get 9 bottles which are completely filled with juice, 3 half filled bottles and 9 empty bottles. Now you can easily divide it amongst three friends.
