Question - 1:1. A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train??

1. 120 metres
2. 180 metres
3. 324 metres
4. 150 metres

Show/Hide Answer

Answer = D - 150 metres
Explanation: No Explanation

Question - 2:A train 100 m long is running at the speed of 30 km/hr. Find the time taken by it to pass a man standing near the railway line. ?

1. 10 sec.
2. 12 sec.
3. 14 sec.
4. 16 sec.

Show/Hide Answer

Answer = B - 12 sec.
Explanation: Speed of the train = (30 x 5/18)m/sec
= (25 / 3) m/sec.
Distance moved in passing
the standing man = 100 m.
Required time taken = 100 /( 25 / 3)
=(100 x 3 / 25) sec
= 12 sec.

Question - 3:A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long??

1. 65 sec
2. 89 sec
3. 100 sec
4. 150 sec

Show/Hide Answer

Answer = B - 89 sec
Explanation: No Explanation

Question - 4:Two trains 140 m and 160 m long run at the speed of 60 km/hr and 40 km/hr respectively in opposite directions on parallel tracks. The time (in seconds) which they take to cross each other, is: ?

1. 9
2. 9.6
3. 10
4. 10.8

Show/Hide Answer

Answer = D - 10 .8
Explanation: Relative speed = (60 + 40) km/hr = 100 x 5/18 m/sec = 250 / 9 m/sec.
Distance covered in crossing each other = (140 + 160) m = 300 m.
Required time = [(300 x 9)/250] sec = 54/5 sec = 10.8 sec.

Question - 5:A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is:?

1. 45 km/hr
2. 50 km/hr
3. 54 km/hr
4. 55 km/hr

Show/Hide Answer

Answer = B - 50 km/hr
Explanation: No Explanation

Question - 6:A man sitting in a train which is travelling at 50 kmph observes that a goods train, travelling in opposite direction, takes 9 seconds to pass him. If the goods train is 280 m long, find its speed.
?

1. 52 kmph.
2. 62 kmph.
3. 72 kmph.
4. 80 kmph.

Show/Hide Answer

Answer = B - 62 kmph.
Explanation: No Explanation

Question - 7:Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:?

1. 50 m
2. 72 m
3. 80 m
4. 82 m

Show/Hide Answer

Answer = B - 72 m
Explanation: No Explanation

Question - 8:A train takes 18 seconds to pass completely through a station 162 m long and 15 seconds through another station 120 m long. The length of the train is?

1. 70 m
2. 80 m
3. 90 m
4. 100 m

Show/Hide Answer

Answer = C - 90 m
Explanation: Let the length of the train be x metres. = x + 162 / 18

= x + 120 / 15

= 15( x+162)

= 18(x+120)

x= 90.

Question - 9:A train is moving at a speed of 132 km/br. If the length of the train is110 metres, how
long will it take to cross a railway platform 165 metres long??

1. 15/2 Sec
2. 15/3 Sec
3. 15/4Sec
4. 14/2 Sec

Show/Hide Answer

Answer = A - 15/2 Sec
Explanation: Speed of train = 132 *(5/18) m/sec = 110/3 m/sec.
Distance covered in passing the platform = (110 + 165) m = 275 m.
Time taken =275 *(3/110) sec =15/2

Question - 10:The length of the bridge, which a train 130 metres long and travelling at 45 km/hr can cross in 30 seconds, is: ?

1. 200 m
2. 225 m
