(A) 14 Second
(B) 16 Second
(C) 17 Second
(D) 18 Second
Correct Option is: D
Speed of the train = 30 km/hr
Speed of man = 3 km/hr
Length of the train = 165m
If direction is given in opposite direction then we add both speed.
That is (30 + 3 )= 33 km/hr
Convert km/hr into m/s
33km /hr = (33 * 5 / 18) m/s = 55/6 m/s
If the train time taken to passing a man who running in opposite direction
That is 55/6 m/s
So we can easily get the distance of m/s
So it cover 165 m
i.e., 165 * 6 /55 = 18 sec.
