This set of Aptitude Questions and Answers (MCQs) focuses on “Two Trains – Set 2”.

1. Two trains crosses each other in 9 seconds travelling in the opposite direction. Find the combined length of the trains if their speeds are 76 kmph and 63 kmph.

a) 347.5 m

b) 347.3 m

c) 347.1 m

d) 346.9 m

View Answer

Explanation: The relative speed = 76 + 63 = 139 kmph = 38.61 m / s

The distance covered = 38.61 * 9 = 347.49 m.

2. Two trains crosses each other in 99 seconds travelling in the same direction. Find the combined length of the trains if their speeds are 76 kmph and 63 kmph.

a) 357.5 m

b) 347.5 m

c) 337.5 m

d) 327.5 m

View Answer

Explanation: The relative speed = 76 – 63 = 13 kmph = 3.611 m / s

The total distance covered = 99 * 3.611 = 357.489 m.

3. Two trains cross each other at speed 57 kmph and 87 kmph. If both the trains move in the same direction, find the combined length of the trains. The time taken by the train to cross each other is 85 seconds.

a) 708 m

b) 709 m

c) 710 m

d) 711 m

View Answer

Explanation: The relative speed = 87 – 57 = 30 kmph = 8.33 m / s

The total distance covered = 8.33 * 85 = 708.05 m.

4. Two trains cross each other at speed 57 kmph and 87 kmph. If both the trains move in the opposite direction find the combined length of the trains. The time taken by the train to cross each other is 15 seconds.

a) 500 m

b) 600 m

c) 700 m

d) 800 m

View Answer

Explanation: The relative speed = 57 + 87 = 144 kmph = 40 m / s

The total distance covered = 40 * 15 = 600 m.

5. Two trains cross each other at a speed of 120 kmph and 145 kmph. If they move in the same direction and take 50 seconds to cross each other, find the combined length of both the trains.

a) 247 m

b) 347 m

c) 274 m

d) 374 m

View Answer

Explanation: The relative speed = 145 – 120 = 25 kmph = 6.94 m / s

The total distance covered = 6.94 * 50 = 347 m.

6. Two trains cross each other at a speed of 120 kmph and 145 kmph. If they move in the opposite direction and take 9 seconds to cross each other, find the combined length of both the trains.

a) 662.5 m

b) 772.5 m

c) 882.5 m

d) 992.5 m

View Answer

Explanation: The relative speed = 120 + 145 = 265 kmph = 73.61 m / s

The total distance covered = 73.61 * 9 = 662.49 m.

7. Two trains cross each other at a speed of 93 kmph and 65 kmph. If both the trains move in the same direction and take 56 seconds to cross each other, find the combined length of the trains.

a) 435.45 m

b) 435.12 m

c) 435.21 m

d) 435.54 m

View Answer

Explanation: The relative speed of the trains = 93 – 65 = 28 kmph = 7.77 m / s

The total distance covered = 7.77 * 56 = 435.12 m.

8. Two trains cross each other at a speed of 93 kmph and 65 kmph. If both the trains move in the opposite direction and take 17 seconds to cross each other, find the combined length of the trains.

a) 746 m

b) 745 m

c) 744 m

d) 743 m

View Answer

Explanation: The relative speed = 93 + 65 = 158 kmph = 43.88 m / s

The total distance covered = 43.88 * 17 = 745.96 m.

9. Two trains cross each other in 143 seconds with a speed of 123 kmph and 154 kmph. Find the length of the trains combined if the trains are moving in the same direction.

a) 833.69 m

b) 833.96 m

c) 823.69 m

d) 823.96 m

View Answer

Explanation: The relative speed = 154 – 123 = 21 kmph = 5.83 m / s

The total distance covered = 5.83 * 143 = 833.69 m.

10. Two trains cross each other in 13 seconds with a speed of 123 kmph and 154 kmph. Find the length of the trains combined if the trains are moving in the opposite direction.

a) 1 km

b) 1.2 km

c) 1.3 km

d) 1.4 km

View Answer

Explanation: The relative speed = 123 + 154 = 277 kmph = 76.94 m / s

The total distance covered = 76.94 * 13 = 1000.22 m.
