Hey user here's ur answer :-)

This is nothing just confusing count ....
just imagine u have 100rs in your hand...u went to shop and purchased for 40rs and he will keep 60 in ur hand and next u will go spend 30rs and shopkeeper will give u 30rs and u will spend 18rs then he will keep 12rs in your hand and next u will buy for that 12 rs ....so there is no additional amount in your hand...here the whole expenditure is done from that 100rs only....so there is no chance of 12rs....here it is for confusing


hope it helps
