When I was a little girl, one day my mother had left a bowl of gooseberries to be shared between my two sisters Lalitha, Vasantha and myself. I went home first. I ate what I thought was my share of gooseberries and left. Then Lalitha arrives. She thought she was the first one to arrive and ate the number of gooseberries, she thought was her share and left. Lastly Vasantha arrived. She again thought she was the first one to arrive and she took what she thought was her share and left 8 gooseberries in the bowl.

When we three sisters met in the evening we reliazed what had happened and my mother distributed the remaining 8 gooseberries in a fair share.

The Problem of the Music concert

admin — Fri, 27 Nov 2009 09:55:00 +0000

Recently I was at a music concert in Calcutta. I was sitting only one hundred feet away from the musicians.

The performance was being broadcasted. My sister Vasantha who lives in Bangalore also heard the same concert on the radio. I am sure you know that Bangalore is over a thousand miles away from Calcutta, and also that sound travels at 1100 feet per second.

Do you think there was any difference in the times at which the music was heard by Vasantha and myself? If so which one of us did hear the given note first?
