Each new group of Management Trainees (MT) have to go through a four month rigorous training schedule, after which they have to pass through a test consisting of a written assessment and a case-analysis. The top hundred ranked Management Trainees (MT) based on the performance in the test are confirmed as Management Executives (ME). The rest are given the opportunity of undergoing the training for four months one more time along with the next batch of Management Trainees (MT) and then passing through the subsequent test consisting of the written assessment and case-analysis. The Management Trainee (MT) who fails to get confirmed as a Management Executive (ME) the second time is fired.

Directions for question:

Mr Vinay Dube, the CEO of Akasa Air, decided to reinforce his fleet of aircrafts to pump up the profitability of Akasa Air. However recession was round the corner, and being the intelligent entrepreneur that he was, wanted to do so at the minimum cost to the Akasa Air capital. So he initiated a reconnaissance of the condition of the then defunct Kingfisher Airlines (KFA) aircrafts lying at the various airports of India, with the aim of buying them from the Airport Authority of India and the tax authorities, who would be more than willing to auction them at a nominal cost to any buyer who would be remotely interested. He would then repair them to make them airworthy, and use them in the Akasa Air fleet. The repairing was the actual big budget expense that would have to be undertaken.

The result of the reconnaissance yielded the fact that there were ten modern Airbus jet airliners of A319 and A380 version of Kingfisher Airlines (KFA) which were in very decent condition and could very well be used after repairs of the issues created by lack of usage for a very long time. The ten aircrafts were coded with the English letters from A to J. 

The maintenance engineers submitted a survey report to Mr Dube on the estimate of the expenditure behind repairs of the aircrafts A to J. All the expenditures behind repairs (in Rs crores) of each aircraft were integral. The repairs with an estimated cost of rupees ten to twenty crores were termed as ‘minor repairs’, that of rupees thirty to forty crores as ‘medium repairs’ and that of rupees fifty to sixty crores as ‘major repairs’.

The report was in the form of a Scatter Graph as shown below :

The report also stated that :

a) Aircrafts coded A, C, E, G and I would not need minor repairs, aircrafts coded B, D, F, H and J would not need medium repairs and aircrafts coded C, F and I would not need major repairs

b) Aircrafts coded D to I would need different repairing costs

c) Aircraft coded G needed the maximum and aircraft coded H the minimum repairing expenditure.
