Solution to Puzzle #194: Adjacent Cells on a Chessboard

Posted on September 17, 2017 by Alok Goyal

I got only two correct answers for this puzzle – from Suman Saraf and Pratik Poddar – thank you both and well done!

I am taking the liberty of copying the answer from Pratik – I find it to be very succinctly articulated.

From square marked 1 to square marked 64, the maximum manhattan distance possible between the two squares is 14 and the maximum difference between any two numbers is 63. Since 63/14>4, there has to be at least one step where the jump is greater than 4. Hence proved.

Hope you all enjoyed the puzzle!
