Krishna and Bala decided to have a bicycle race. But the problem was that they had only one bicycle between them! Krishna had a solution. As the road to the airport had a stone demarcating every kilometer, he would ride from the first stone to the fifth, and Bala could ride the remaining distance from the fifth to the tenth stone.

My club has five cultural groups. They are literary, dramatic, musical, dancing and painting groups. The literary group meets every other day, the dramatic every third day, the musical every fourth day, the dancing every fifth day and the painting every sixth day. The five groups met, for the first time on the New Year’s day of 1975 and starting from that day they met regularly according to schedule.
Now, can you tell how many times did all the five meet on one and the same day in the first quarter? Of course the New Year’s day is excluded.
One more question-were there any days when none of the groups met in the first quarter and if so how many were there?
