I really need solutions for these please!!

Question 1: The performance of twelve selected international airlines is given in the following table. Operating costs, non-flight assets, passenger and non-passenger revenues are measured in appropriate money units (US$). The first two variables are inputs and the last two are outputs. Airlines 1 2 3 4 5 Operating Costs 6730 3457 6779 3341 3239 9560 9874 8032 1878 8098 2481 4225 Non-flight assets 3934 2360 6474 3581 2003 6267 4145 3272 1916 3310 2254 4557 Revenue Passenger 26677 22112 52363 26504 26677 124055 122528 95011 19277 41925 27754 33081 Non-passenger Revenue 7688 969 2001 1297 697 1266 1404 572 972 3398 982 539 6 7 8 9 10 11 12 Any attempt to measure operational efficiency will play an important role in benchmarking and in the design of management strategies for future improvement of the sector's performance. (a) Develop a DEA model to evaluate the efficiency score of airline no 10. (b) Solve your model developed above in part (a) using Excel solver. Is airline 10 efficient? Explain. (c) Repeat parts (a) and (b) for airline 4. Question 1: The performance of twelve selected international airlines is given in the following table.
