My friend came to my home for vacation. Every day we played a chess game.Where the looser should give the winner a choclate.Finally one day my friend gave me 8 choclates even though she won 12 games.How many days did she stay in my home?
is the answer 20 days??

sorry for such posts!! i am preparing for few exams and these questions are killing me because i make very silly mistakes in Maths.

kindly bear with me!!
