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.

Piggy Bank will be Half-full on 13th Day

If everyday Piggy banks gets double then previous day, it means on 14th day amount that i received to be added in piggy bank was similar to that i already had. and if it gets full on 14 day means it was half on 13th day.
