DQ 19 Answer
1. No, its not possible.
2. And the 2nd part "how" (which should have been a why in this case
Imagine a chess board of 6 by 6 size. If you remove any two diagonally opposite corners, you end up removing two squares of the same color. Now the remaining grid of 34 pieces has 18 pieces of 1 color and 16 of another. If you try to divide this into 17 1*2 pieces you require 17 white and 17 blacks, which is not possible.
I have got 13 responses till now. 2 of them wrong , 9 which got the first part right and only 2 which got all correct. But I am overwhelmed by the enthusiasm as each and every one of them tried to put some effort (mostly painstaking with examples!) to prove or disprove the hypotheses.
2 (both correct): 125 INR each
9 (1st part correct): 100 INR each
