Ten people sit at a round table. The sum of Rupees 10 is to be distributed among them so that each person receives the average of what each of his two neighbours receives.
In how many different ways can this be achieved ?
[Given: 1 Rupee = 100 Paise]
But you do have to think. You have to think of various combinations, and when you only find 1,1,1,1,1,... you have to figure out why that seems to be the only answer.
