A shop sells chocolates at Rs 1 each. You will be able to exchange 3 wrappers for 1 chocolate. If you hav Rs 15, How many chocolates can you get totally ?

Rs 15 = 15 chocolates(in which you will get 15 wrappers),

15 wrappers = 5 chocolates(in which you will get 5 wrappers),

those 5 wrappers = 1 chocolate(you will get a wrapper here) + 2 wrappers left,

so remaining 3 wrappers = 1 chocolate.


Count the total chocolates..It is 22.
