An aeroplane weighing 63,000 kg flies up from sea level to a height of 8000 meter. Its engine run with pure normal octane (C_(8)H_(18)) has a 30% efficiency. Calculate the fuel cost of the flight if octane sells at Rs. 3 per litre. Given density of octane =0.705 g mL^(-1) , heat of combustion of octane =1300 kcal mol^(-1) (g=981 m//s^(2))
