Two pence will be paid on the second day,
Four pence will be paid on the third day.

John, a 5-year-old boy, was really fond of the chocolates. He asked his Mother to give him some money to buy his favourite chocolates. His Mother gave him $45.

Also, if you give me the wrappers of three chocolates, I will give you one for the exchange.
