whence this question was asked to me... i was doing a lot of calculations ... but the body language of the person who questioned me suggested that there is some trick in it...
so i answered 1/2... and it proved to be right ...and i somehow convinced him of the way i found out the answer but i dont have an explanation...now i tried to build up an explanation but could nt come up with a convincing one... so looking forward to some of the best explanations :) On Sep 10, 10:21 pm, ankur aggarwal <ankur.mast....@gmail.com> wrote: > crazy man in the airplane A line of 100 airline passengers is waiting to > board a plane. they each hold a ticket to one of the 100 seats on that > flight.
