) Look at this series: 14, 28, 20, 40, 32, 64, what number should come next? Assume that the rate of consumption of coal by a locomotive engine varies as the square of its speed and is 1000 kg per hour when the speed is 60 kmph, when in motion. If coal costs the railway company Rs.15 per 100 kg and if the other expenses of running the train is Rs.12 per hour, find a formula for the cost in paise per kilometre when the speed is S km per hour.
options:
(1200/S)+(25S^2/6)
(1200/S)+(5S^2/18)
(1200/S)+(25S/6)
