Five airline companies P, Q, R, S and T applied to government permission to run their flights in a certain city. The government gave them permission to have certain number of trips every year but with uniform frequency based on the fee they paid. A regular traveler observed the trips of different flights on different days. P on 2nd July, Q on 3rd July, R on 4th July and so on. After some days they also observed the below trips: T on July 30th, S on July 31st and R on August 1st and so on. No flight has a trip every day. Every flight has a trip at least once in every week.
Question 1: Frequency of which flights among P, Q, R, S can be uniquely found out ?
Question 2: Assume that each flight has a distinct frequency. For what all flights can their frequency be definitely inferred ?
My thoughts on the puzzle :-
