Question

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. After
dividing them (both bottles and juice) equally how much empty bottles each will get? ​

Answer 1

There are total of 7 full , 7 half filled and 7 empty bottles .

Each friend must get equal no. of bottles and juice . We will take the fully filled bottles and make them half empty in the and put the half juice in the empty bottles .

By doing this we will now get 21 half filled bottles.

Now each friend can get 7 bottles each of half filled juice .

Therefore at the end the friends will get 0 empty bottles .
