Can anyone solve this problem?
A man travels to chinsura everyday for work. His wife drives him over to howrah station every morning and in the evening exactly at 6:00PM she picks him up from the station and takes him home.
One day, he was left off at work an hour earlier and So, he arrived at the Howrah station at 5:00 PM instead of 6:00PM. He started walking home. However the met his wife enroute to the station and got into the car. They drove home arriving 10 minutes earlier that usual.
How long did the man have to walk, before before he was picked up by his wife?
