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.

On which day will your piggy bank be half-full?
