Train Aptitude Questions are complex in nature and require an understanding of Numbers SystemsRatio and ProportionPercentage Calculation, Speed, Time and Distance, and Math Tables. Example questions and practice Train aptitude questions are given in this article.

Nowadays, questions in exams are mixed with multiple concepts and it requires practice and a deep understanding of basic concepts along with quickly identifying numbers.

## Types of Train Aptitude Questions

Two types of train Aptitude questions in which trains traveling direction are used. There can be two possible scenarios in train traveling direction:

1. Trains Traveling in the Same Direction
2. Trains Traveling in Opposite Direction

### Trains Travelling in the Same Direction

Let’s say Train 1 as T1 of length L1 and traveling at speed of S1. Train 2 as T2 of length L2 and traveling at speed of S2. If both the trains are traveling in the same direction. Then at what time train will cross each other. Can be calculated from the below formula:

Time Taken = (L1 + L2) / (S1 – S2)

### Trains Travelling in Opposite Direction

Let’s say Train 1 as T1 of length L1 and traveling at speed of S1. Train 2 as T2 of length L2 and traveling at speed of S2. If both the trains are traveling in the opposite direction. Then at what time train will cross each other. Can be calculated from the below formula:

Time Taken = (L1 + L2) / (S1 + S2)

## Solved Examples on Train Aptitude Questions

Below are a few solved examples on Train Aptitude Questions:

Example 1: Two trains whose length is 300m and 200m and their respective speed is 36 kmph and 24 kmph. Both trains are traveling in opposite directions to each other. Find how much time both trains will cross each other?

Solution 1: Given the length of Train 1 is 300m and the Speed is 36 kmph.
Length of Train 2 is 200m and Speed is 24 kmph.
Total Lenght = 300 + 200 = 500 m or 1/2 KMs.
Now applying this values in formula as below:
=> Time taken = 1/2 ( 1 / (36 + 24))
=> Time taken = 1/2 ( 1 / (60))
=> Time taken = 1/120
=> Time taken = 60 / 120 = 30 Seconds

Example 2: Two trains whose length is 300m and 200m and their respective speed is 36 kmph and 24 kmph. Both trains are traveling in the same direction to each other. Find how much time both trains will cross each other?

Solution 2: Given the length of Train 1 is 300m and the Speed is 36 kmph.
The length of Train 2 is 200m and the Speed is 24 kmph.
Total Lenght = 300 + 200 = 500 m or 1/2 KMs.
Now applying this values in formula as below:
=> Time taken = 1/2 ( 1 / (36 – 24))
=> Time taken = 1/2 ( 1 / (12))
=> Time taken = 1/24
=> Time taken = 60 / 24 = 2 Minutes and 30 Seconds

## Practice Train Aptitude Questions

Below are a few Practice Train Aptitude Questions:

1. Two trains whose length is 500m and 500m and their respective speed is 36 kmph and 24 kmph. Both trains are traveling in the opposite direction to each other. Find how much time both trains will cross each other?
2. Two trains whose length is 500m and 500m and their respective speed is 36 kmph and 24 kmph. Both trains are traveling in the same direction to each other. Find how much time both trains will cross each other?
3. Train A speed is 72 kmph and Train B speed is 18 kmph. The length of both Trains is 200 m and 100 m, respectively. Both trains are traveling in the same direction. Find how much time both will cross each other?
4. Train A speed is 72 kmph and Train B speed is 18 kmph. The length of both Trains is 200 m and 100 m, respectively. Both trains are traveling in the opposite direction. Find how much time both will cross each other?
5. A train whose length is 200m and traveling at a speed of 36 kmph, crosses another train that is traveling at a speed of 108 kmph in 20 seconds. Find the length of another train?

## Final Words

Practicing the above Train aptitude questions is not the end of your practice, but it’s the start of a new journey to apply logic on Train Aptitude Questions with multiple approaches in a right and faster way.

For cracking competitive exams one must practice Train Aptitude Questions without a calculator is a must. At last, during the exam, if a solution for the Train AptitudeQuestions cannot be found easily then mark that question to revisit and move ahead instead of wasting time and energy.
