Daily Quiz 20 - Win 1000 cc cash + Food

Day 1,812, 09:15 by Wild Quark
Thank you Sponsors!

DQ 19 Answer

1. No, its not possible.
2. And the 2nd part "how" (which should have been a why in this case :p) is-

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.

DQ 20: By olivermellors: PM olivermellors your answer

Chess is played on a board with 64 squares. The inventor was offered a reward for having invented the game: “name your price”. He asked for either:

a. One kernel of rice for the first square, and double the previous amount for each subsequent square.

b. A nice piece of land to grow rice on for the rest of his life. (he is expected to live 25 more years)

Which is the richest reward? Explain.
