aah balla bujhe, hawaguji, narishau na bro, nabujhe pachi k garne ta ..dada timi chai geda khau hai :) ooh ok, the main point i was missing out here was, The census guy knows the number of the next house, even though we certainly dont, so if the problem had not had two answers that resulted 13, it could have has several answers, but it has 2 answers that has the same answer, and that is how census guy is lost, because of those 2 answers.. :) thax peeps :) la mero pali abu, its a physics problem.. i was listening to my jagjit singh CD and crusing at 10 mph hagi, then i had to suddenly stop at the stop sign. On the very moment when i stopped at the stop sign, a piece of pebble got wedged on my tire. now the same piece of pebble will role with the tire and its position will vary from the paved road. The tire is about 24.9 inches, now what will be the distance of the piece of pebble from the paved road when i have went about 200 inches?
