We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

The ELADR token was designed to incentivize and reward community members as a proof of contribution. Token holders are also granted access to EduLadder.com premium features as well as associated ELADR token enabled apps.

Aptitude Test :: Problems on Trains -1

How to study this subject


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

A.120 metresB.180 metres
C.324 metresD.150 metres
Answer & Explanation

Answer: Option D

Explanation:

Speed=60 x5m/sec=50m/sec.
183
Length of the train = (Speed x Time) =50x 9m = 150 m.
3

2. 

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:

A.45 km/hrB.50 km/hr
C.54 km/hrD.55 km/hr
Answer & Explanation

Answer: Option B

Explanation:

Speed of the train relative to man =125m/sec
10
   =25m/sec.
2
   =25x18km/hr
25

   = 45 km/hr.

Let the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr.

 x - 5 = 45          x = 50 km/hr.


3. 

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

A.200 mB.225 m
C.245 mD.250 m
Answer & Explanation

Answer: Option C

Explanation:

Speed =45 x5m/sec=25m/sec.
182

Time = 30 sec.

Let the length of bridge be x metres.

Then,130 + x=25
302

 2(130 + x) = 750

 x = 245 m.


4. 

Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively and they cross each other in 23 seconds. The ratio of their speeds is:

A.1 : 3B.3 : 2
C.3 : 4D.None of these
Answer & Explanation

Answer: Option B

Explanation:

Let the speeds of the two trains be x m/sec and y m/sec respectively.

Then, length of the first train = 27x metres,

and length of the second train = 17y metres.

27x + 17y= 23
x+ y

 27x + 17y = 23x + 23y

 4x = 6y

x=3.
y2


5. 

A train passes a station platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform?

A.120 mB.240 m
C.300 mD.None of these
Answer & Explanation

Answer: Option B

Explanation:

Speed =54 x5m/sec = 15 m/sec.
18

Length of the train = (15 x 20)m = 300 m.

Let the length of the platform be x metres.

Then,x + 300= 15
36

 x + 300 = 540

 x = 240 m.


6. 

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

A.65 secB.89 sec
C.100 secD.150 sec
Answer & Explanation

Answer: Option B

Explanation:

Speed =240m/sec = 10 m/sec.
24
 Required time =240 + 650sec = 89 sec.
10


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:

A.50 mB.72 m
C.80 mD.82 m
Answer & Explanation

Answer: Option A

Explanation:

Let the length of each train be x metres.

Then, distance covered = 2x metres.

Relative speed = (46 - 36) km/hr

   =10 x5m/sec
18
   =25m/sec
9
2x=25
369

 2x = 100

 x = 50.


8. 

A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long?

A.40 secB.42 sec
C.45 secD.48 sec
Answer & Explanation

Answer: Option A

Explanation:

Formula for converting from km/hr to m/s:   X km/hr =X x5m/s.
18
Therefore, Speed =45 x5m/sec=25m/sec.
182

Total distance to be covered = (360 + 140) m = 500 m.

Formula for finding Time =Distance
Speed
 Required time =500 x 2sec= 40 sec.
25


9. 

Two trains are moving in opposite directions @ 60 km/hr and 90 km/hr. Their lengths are 1.10 km and 0.9 km respectively. The time taken by the slower train to cross the faster train in seconds is:

A.36B.45
C.48D.49
Answer & Explanation

Answer: Option C

Explanation:

Relative speed = (60+ 90) km/hr

   =150 x5m/sec
18
   =125m/sec.
3

Distance covered = (1.10 + 0.9) km = 2 km = 2000 m.

Required time =2000 x3sec = 48 sec.
125


10. 

A jogger running at 9 kmph alongside a railway track in 240 metres ahead of the engine of a 120 metres long train running at 45 kmph in the same direction. In how much time will the train pass the jogger?

A.3.6 secB.18 sec
C.36 secD.72 sec
Answer & Explanation

Answer: Option C

Explanation:

Speed of train relative to jogger = (45 - 9) km/hr = 36 km/hr.

   =36 x5m/sec
18

   = 10 m/sec.

Distance to be covered = (240 + 120) m = 360 m.

 Time taken =360sec= 36 sec.
