A Train requires 12 seconds to pass a pole while it requires 27 seconds to cross a stationary train which is 300 mtrs long. Find the speed of the train.\nOptions:\n(A) 60 kmph\n(B) 75 kmph\n(C) 80 kmph\n(D) 85 kmph\n(E) 72 kmph Hmmm, my stream of consciousness:

In 12s the train crosses the pole and in 27 sec the train crosses one more stationary train\nIn 15 sec the train travels a distance of 300 mtrs\nSpeed = 300/15 = 20 m/s = 20 (3600/1000) = 20 * 18/5 = 72 kmph So, the answer is (E).
