DIRECTIONS for the following four questions:
A low-cost airline company connects ten India cities, A to J. The table below gives the distance between a pair of airports and the corresponding price charged by the company. Travel is permitted only from a departure airport to an arrival airport. The customers do not travel by a route where they have to stop at more than two intermediate airports.
If the prices include a margin of 10% over the total cost that the company incurs, what is the minimum cost per kilometer that the company incurs in flying from A to J?
The minimum cost from A to J we know is 2275.
Let the CP to company be C
Since 10% over actual CP is the total price i.e. $$\text{CP}\times1.1 = 2275 \rightarrow CP = \frac{2275}{1.1}$$
The total distance is 1950+1400=2350 Km.
Cost per Km = $$\dfrac{\frac{2275}{1.1}}{2350}$$ = Rs 0.88/Km
