This set of Aptitude Questions and Answers (MCQs) focuses on “Train and Pole”.
1. A train moving with a speed of 23 kmph passes a pole in 12.9 seconds. Find the speed of the train.
a) 82 m
b) 83 m
c) 84 m
d) 85 m
View Answer
Explanation: The speed of the train = 23 kmph = 6.38 m / s
The total distance covered by the train in 12.9 seconds = the length of the train
The length of the train = 6.38 * 12.9 = 82.302 m.
2. A train moving at a speed of 58 kmph passes a pole in 7.4 seconds. Find the length of the train.
a) 119.2 m
b) 112.3 m
c) 119.4 m
d) 112.5 m
View Answer
Explanation: The length of the train = the distance covered by the train in 7.4 seconds
The speed of the train = 58 kmph = 16.11 m / s
The distance covered = 16.11 * 7.4 = 119.214 m.
3. A train moving with a speed of 73 kmph passes a man walking with a speed of 7 kmph in the same direction in 32 seconds. Find the length of the train.
a) 585 m
b) 586 m
c) 587 m
d) 588 m
View Answer
Explanation: The relative speed = 73 – 7 = 66 kmph = 18.33 m / s
The distance covered = 18.33 * 32 = 586.56 m.
4. A train with a speed of 113 kmph passes a man with a speed of 104 kmph moving in the same direction in 98 seconds. Find the length of the train.
a) 220 m
b) 230 m
c) 245 m
d) 255 m
View Answer
Explanation: The relative speed = 113 – 104 = 9 kmph = 2.5 m / s
The distance covered = 98 * 2.5 = 245 m.
5. A train with a speed of 113 kmph passes a man with a speed of 104 kmph moving in the opposite direction in 9 seconds. Find the length of the train.
a) 542.43 m
b) 554.32 m
c) 543.32 m
d) 532.42 m
View Answer
Explanation: The relative speed = 113 + 104 = 217 kmph = 60.27 m / s
The distance covered = 60.27 * 9 = 542.43 m.
6. A train moving with a speed of 73 kmph passes a man walking with a speed of 7 kmph in the opposite direction in 3.2 seconds. Find the length of the train.
a) 64 m
b) 70 m
c) 71 m
d) 78 m
View Answer
Explanation: The relative speed = 80 kmph = 22.2 m / s
The total distance covered = 22.2 * 3.2 = 71.04 m.
7. A train crosses pole at a speed of 12 kmph in 123 seconds. Find the length of the train.
a) 409 m
b) 410 m
c) 412 m
d) 415 m
View Answer
Explanation: The speed of the train = 12 kmph = 3.33 m / s
The distance covered = 123 * 3.33 = 409.59 m.
8. A train crosses a pole at a speed of 24 kmph in 15 seconds. Find the length of the train.
a) 95 m
b) 100 m
c) 110 m
d) 150 m
View Answer
Explanation: The speed of the train = 24 kmph = 6.66 m / s
The distance covered = 6.66 * 15 = 99.9 m.
9. A train covers 6 km in 12 minutes. Find the length of the train if it passes a pole in 12 seconds.
a) 120 m
b) 110 m
c) 100 m
d) 95 m
View Answer
Explanation: The speed of the train = 6 / 12 = 0.5 km per minute = 30 kmph = 8.33 m / s
The distance = speed * time = 8.33 * 12 = 99.96 m.
10. A train crosses a man in 7 seconds. If the length of the train in 763m, find the speed of the train.
a) 392.2 kmph
b) 392.4 kmph
c) 392.5 kmph
d) 395 kmph
View Answer
Explanation: The speed of the train = distance / time = 763 / 7 = 109 m / s = 392.4 kmph.
