(i )Lorry that started at 6am will meet all the lorries which started between 6am to 2pm from bangalore.We will not consider here the 3pm as it will reach at the destination.So This lorry will cross 9 lorries from opposite direction.
(ii). Now lorry starting from 6pm will met all the lorry that started from 10am to 10pm.Here we will not consider 9 AM as that 9 AM lorry will reach exactly at 6 PM.So the lorry which will leave at 6PM will meet 13 lorries on the way from opposite direction. (Answer)
