Mother gives you money every day to put in your new piggy bank. She gives money to you in such a way that the money in the piggy bank doubles with each passing day.

If you already have Rs 1 in the piggy bank and Dad gives you Rs 1 the first day, 2 the second day, 4 the third day and so on, then your piggy bank gets full on the 14th day.

If I said that in three days' time it would be a Thursday, I am sure that most of you would have no difficulty telling me that today was a Monday.

Try this one then. Yesterday was two days before Monday. What day is it today? Yes, you're right again. It's Sunday. Do you get the idea?

Now let's tackle a similar question from The National Mathematics Contest (1991) Paper:

Three days ago, yesterday was the day before Sunday. What day will it be tomorrow?

The banks are only open on Tuesdays, Thursdays, and Saturdays.
The eye doctor is closed on Saturday.
