(A) 10 seconds
(B) 15 seconds
(C) 25 seconds
(D) 45 seconds
Correct Option is: A
Length of the train = 240 m
Time taken to cross an object = 6 seconds
Speed of the train = Length of the train / Time taken to cross an object
= 240/6 m/s
= 40 m/s
Length of the pole = 162.5 m
Time taken to cross the pole= (Length of the train + Length of the pole) / Speed of the train
= (240 + 162.5)/40
= 402.5/40
= 10.06 seconds
Hence the answer is 10 seconds.
