(Ans). (A)
(Question). A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 340 m long?
Options:
(A) 56 sec
(B) 42 sec
(C) 45 sec
(D) 48 sec
(E) 50 sec
(CoT). Speed = 45 * 5/18 = 25/2 m/sec
Total distance covered = 360 + 340 = 700 m
Required time = 700 * 2/25 = 56 sec

(Ans). (E)
(Question). A train running at the speed of 60 km/hr crosses a pole in 9 sec. What is the length of the train?
Options:
(A) 120 m
(B) 190 m
(C) 115 m
(D) 110 m
(E) 150 m
(CoT). Speed = 60 * 5/18 = 50/3 m/sec
Length of the train = speed * time = 50/3 * 9 = 150 m

(Ans). (B)
(Question). A 160 meter long train crosses a man standing on the platform in 9 sec. What is the speed of the train?
Options:
(A) 96 kmph
(B) 64 kmph
(C) 52 kmph
(D) 86 kmph
(E) 76 kmph
(CoT). S = 160/9 * 18/5 = 64 kmph

(Ans). (D)
(Question).
A train 350 m long, running with a speed of 63 km/hr will pass a tree in?
Options:
(A) 15 sec
(B) 16 sec
(C) 18 sec
(D) 20 sec
(E) 25 sec
(CoT). Speed = 63 * 5/18 = 35/2 m/sec
Time taken = 350 * 2/35 = 20 sec
