CAT 2017 Slot 1 DILR · Question 1
A new airlines company is planning to start operations in a country. The company
has identified ten different cities which they plan to connect through their network to start
with. The flight duration between any pair of cities will be less than one hour. To start
operations, the company has to decide on a daily schedule.
The underlying principle that
they are working on is the following:
Any person staying in any of these 10 cities
should be able to make a trip to any other city in the morning and should be able to return by
the evening of the same day.
If the underlying principle is to be satisfied in such a way that the journey between any
two cities can be performed using only direct (non-stop) flights, then the minimum
number of direct flights to be scheduled is:
- A.45
- B.90
- C.180
- D.135
