Answer the following question, with explanation first.
A Train requires 10 seconds to pass a pole while it requires 30 seconds to cross a stationary train which is 600 mtrs long. Find the speed of the train.\nOptions:\n(A) 110 kmph\n(B) 120 kmph\n(C) 108 kmph\n(D) 100 kmph\n(E) 98 kmph

(C)
In 10s the train crosses the pole and in 30 sec the train crosses one more stationary train\nIn 20 sec the train travels a distance of 600 mtrs\nSpeed = 600/20 = 30 m/s = 30 (3600/1000) = 30 * 18/5 = 108 kmph.

Therefore, the answer is (C)
