Pocket-money

I went down the street with a certain amount of money in my pocket,

and when I returned home I discovered that I had spent just half of it,

and that I now had just as many shillings as I previously had pounds,

and half as many pounds as I then had shillings.

How much money had I spent?

Also see

• Dollars and Cents, which follows exactly the same pattern.
