A shop sells chocolates @ Rs.1 each. You can exchange 3 wrappers for 1 chocolate.
If you have Rs.15/- how many chocolates can you get totally?
You'd get 21 chocolates + have two wrappers which would come in handy when you buy one more chocolate for (Rs. # 16/-) and use its wrapper + the other two to get one more chocolate....
Fraaj is right. 21 chocolates and 2 wrappers left.

Nopes do the math again, 22 is what you get.
15 = 15 wrappers - 15/3 = 5 chocolates (total till now 15+5 = 20)
out of 5 wrappers use 3 (2 wrappers left) to get one more chocolate (total chocolates 15+5+1=21)
remaining 2 wrappers with one chocolate wrapper get another chocolate (total 15+5+1+1 = 22)
