A Drinking Problem (Posted on 2002-12-18) Difficulty: 2 of 5
Four people are in a bar.

Ben owes Glen a drink. Glen owes Rhen two drinks. Rhen owes Sven three drinks. Sven owes Ben four drinks.

To settle up, what is the minimum number of drinks that need to be bought by who for whom?

Sven, Rhen and Glen should buy Ben one drink each.

Thus, the minimum amount of drinks is 3 drinks.
