Comments from Vivek

Hi Vivek,
Thank you for posting your answers to the puzzles. Most of them are on target. Please keep answering the puzzles. I shall post the answers shortly. As you had suggested, I shall reframe the design, with time out and so on... Kindly bear with me for a few days. ( Seeking apology for being late is not proper, I know. However... please wait.)
Prasanna
