You have 15 Rs with you. You go to a shop and shopkeeper tells you price as 1 Rs per chocolate. He also tells you that you can get a chocolate in return of 3 wrappers. How many maximum chocolates you can eat?
Buy and eat 15 chocolates
Return 15 wrappers and get 5 more chocolates.
Return 3 wrappers, get 1 chocolate and eat it (keep 2 wrappers)
Now we have 3 wrappers. Return 3 and get 1 more chocolate.
So total chocolates = 15 + 5 + 1 + 1
