Q 1 - The speed of a train 150 m long is 50 kmph. How much time will it take to pass a platform 600 m long ?
Answer : B
Explanation
Speed =(50*5/18) m/sec. =125/9 m/sec Required time = (600+ 150)/ (125/9) sec.=(750*9/125)sec. =54 sec.
Q 2 - A train travelling at a speed of 30 m/sec crosses a platform 600 m long in 30 sec. The length of the train is?
Answer : D
Explanation
Let the length of the train be X m . then its speed =(600+x)/30 m/sec. ∴ (600+X)/30 =30 ⇒ 600+x =900 ⇒ x =300m
Q 3 - A train 100 m long moving at a speed of 50km/hr crosses a train 120m long coming from opposite side on parallel tracks in 6 sec. The speed of the second train is
Answer : B
Explanation
let the speed of the second train be x kmph.
Their relative speed = (50+x) kmph ={ (50+x)* 5/18) m/sec.
Sum of their lengths = (100+120)m =220 m
220/ [(50+x)*5/18] = 6 ⇒30 (50+x)= 3960
⇒ 30x =(3960-1500) = 2460
X = 82
Speed of the second train = 82 kmph.
Q 4 - A 150 m long train cross a walking at the speed of 6kmph in the opposite direction in 6 sec. The speed of the train is
Answer : B
Explanation
Let the speed of the train be x kmph. Their relative speed = (x+6) kmph = [ (x+6) *5/18]m/sec. ∴ 150/ (x+6)*5/18 = 6 ⇒ 30 (x+6) =(18*150) ⇒ 30x+180= 2700 ⇒ 30x = 2520 ⇒ x = 84 ∴ speed of the train is 84 kmph.
Q 5 - A train takes 5 sec. to pass an electric pole. If the length of the train is 120 m, the time taken by it to cross a railway platform 180 m long ,is
Answer : A
Explanation
Speed of the train = (120/5)m/sec. =24m/sec. Time taken to cross the platform =(120+180)/24 sec. =300/24 sec= 25/2 sec.
Q 6 - A train is running at the rate of 40kmph. A man is going in the same direction parallel to the train at 25kmph . If the train crosses the man in 48 sec. , the length of the train is
Answer : D
Explanation
relative speed = (40-25)kmph =15kmph =(15*5/18) m/sec. =25/6 m/sec. Length of the train = (25/6*48)m= 200 m.
Q 7 - Two man running in opposite directions cross a man standing on the platform in 27 sec. and 17 sec. respectively and they cross each other in 23 seconds. The ratio of their speeds is
Answer : B
Explanation
Let the speed of the two trains be x m/sec. and y m/sec. Length of the first train =(27x)m Length of the second train = (17y)m (27x+17y)/(x+y) = 23 ⇒ 27x+17y = 23x+23 y ⇒4x=6y ⇒ 2x=3y ⇒ x/y 3/2 Ratio of their speed = 3:2
