This set of Aptitude Questions and Answers (MCQs) focuses on “Problems on Trains”. These questions are beneficial for various competitive exams, placement interviews, and entrance tests.

1. A train with a speed of 120kmph passes a man in 15 seconds. Find the length of the train.

a) 200m

b) 300m

c) 400m

d) 500m

View Answer

Explanation: The speed of the train in meter per second = 120 * 1000 / 3600 = 120 * 5 / 18 = 600 / 18 = 100 / 3 m / s

The time taken by the train to travel through the man = 15 seconds

The length of the train = 100 * 15 / 3 = 500 m.

2. A train with a speed of 45kmph passes a man in 20 seconds. Find the length of the train.

a) 150m

b) 200m

c) 250m

d) 300m

View Answer

Explanation: The speed of the train in meters per second = 45 * 5 / 18 = 25 / 2 m / s

The time taken by the train to pass through the man = 20 seconds

The length of the train = 20 * 25 / 2 = 250m.

3. A train with length of 50 m passes a man in 3 seconds. Find the speed of the train.

a) 15 kmph

b) 30kmph

c) 45kmph

d) 60kmph

View Answer

Explanation: The distance covered by the train = the length of the train

The distance covered = 50m

The time taken = 3 seconds

The speed = 50 / 3 m / s = 50 / 3 * 3600 / 1000 = 50 * 18 / (5 * 3) = 60 kmph.

4. A train 150 m in length passes a man in 12 seconds. Find the speed of the train.

a) 40 kmph

b) 45 kmph

c) 50 kmph

d) 55 kmph

View Answer

Explanation: the distance to be covered = the length of the train

The distance to be covered = 150m

The time taken = 12 seconds

The speed = 150 / 12 = 25 / 2 m / s

The speed = 25 / 2 * 18 / 5 kmph = 45 kmph.

5. The speed of a train is 120 kmph and the length of the train is 240 m. find the time it will take to cross a pole.

a) 2.4 seconds

b) 4.8 seconds

c) 7.2 seconds

d) 9.6 seconds

View Answer

Explanation: The distance to be covered = 240 m

The speed = 120 kmph

The speed in meter per second = 120 * 5 / 18 = 100 / 3

The time taken = 240 / 100 * 3 = 7.2 seconds.

6. A train with length 300m crosses a pole at a speed of 50 kmph. Find the time taken by the train to cross the pole.

a) 20.6 seconds

b) 21.6 seconds

c) 22.6 seconds

d) 23.6 seconds

View Answer

Explanation: The speed of the train = 50 kmph = 50 * 5 / 18 meter per second = 125 / 9 m / s

The distance to be covered = 300 m

The time taken to cross 300m = 300 / 125 * 9 = 108 / 5 seconds = 21.6 seconds.

7. A train is 315 m in length and crosses a pole in 27 seconds. Find the speed of the train.

a) 42 kmph

b) 44 kmph

c) 46 kmph

d) 48 kmph

View Answer

Explanation: The distance to be covered = the length of the train

The distance to be covered = 315 m

The time taken = 27 seconds

The speed of the train = 315 / 27 m / s = 35 / 3 m / s = 35 / 3 * (18 / 5) = 42 kmph.

8. A train 405 m in length passes a pole in 45 seconds. Find the speed of the train.

a) 32.4 kmph

b) 23.4 kmph

c) 34.3 kmph

d) 24.3 kmph

View Answer

Explanation: The distance to be covered = the length of the train

The distance to be covered = 405 m

The time taken = 45 seconds

The speed of the train = 405 / 45 = 9 m / s

The speed = 9 * 18 / 5 = 32.4 kmph.

9. A train moving at a speed of 25 kmph crosses a pole in 9 seconds. Find the length of the train.

a) 60 m

b) 62.5 m

c) 65 m

d) 70 m

View Answer

Explanation: The length of the train = the distance covered

The distance covered = speed * time = 25 * 9 / 3600 km = 25 * 5 / 18 * 9 m = 62.5 m.

10. A train covers 120 km in 480 minutes. Find the speed of the train.

a) 3.16 m / s

b) 4.16 m / s

c) 5.16 m / s

d) 6.16 m / s

View Answer

Explanation: The speed of the train = distance / time = 120 / 480 = 0.25 km / minute = 15 kmph

The speed in meter / second = 15 * 5 / 18 = 4.16 m / s.
