## Aptitude basics for Solving Problems on Trains:

The Questions will involve one train or two trains; therefore read the question whether the question involves one train or two trains, because you can decide what formula to use and solve quickly. The entire aptitude question on trains will contain any of these 5 questions. Note that sometimes trains are replaced by some other thing like person, man, car … etc

Single Train Questions (2 Types of questions)

Question 1:

What is the time taken by a train of length ‘L’ metres and travelling at a speed of ‘S’ to pass a pole or a standing man or a signal post or some stationary object?

Explanation

• The Question will contain length of the train ‘L’
• Train’s speed ‘S’ will be given in terms of either km/hr or m/sec.

If speed is given in terms of Km/hr, always remember to convert  it to m/sec which can be done               by this formula: =S x (5/18) m/sec

• You have to find the time taken by the train to pass the stationary object. Use this formula

Time taken to pass the object= L/S sec

Question 2

What is the time taken by a train of length ‘L’ metres and travelling at speed of ‘S’ to pass a pole or a standing man or a signal post or some stationary object of Length ‘M’?

Explanation

• The Question will contain length of the train ‘L’
• Length of the object ‘M’
• Train’s speed ‘S’ will be given in terms of either km/hr or m/sec.

If the speed is given in terms of Km/hr, always remember to convert it to m/sec which is done                  by this formula: =S x (5/18) m/sec

• You have to find the time taken by the train to pass the object of length ‘M’. Follow this procedure

1. You know this: Time taken to pass the object= L/S sec

2. Make changes to the above formula in this way…

Time taken to pass the object of length ‘M’ = (L+M)/S sec

Two Train Questions (3 Types)

Question 3:

What is the taken by the two trains that are of length ‘a’ and ‘b’ respectively and travelling opposite to each other at a speed of ‘u’ and ‘v’ respectively to cross each other?

Explanation

• The Question will contain two trains and its lengths as; ‘a’ of the first train and ‘b’ of the second train.
• The speed of the trains will also be included  as ‘u’ as speed of the first train and ‘v’ as the speed of the second train

If the speed is given in terms of Km/hr, always remember to convert it to m/sec which is done by             this formula

For train 1:      =u x (5/18) m/sec an

For train 2:     = v x (5/18) m/sec

Or

= (u+v) x (5/18) m/sec

• Now you have find out the time taken by the trains to cross each other; use this formula

= (a+b)/ (u+v)

u+v is called as relative speed of trains travelling in opposite direction

Question 4

What is the taken by the two trains that are of length ‘a’ and ‘b’ respectively and travelling in the same direction or parallel to each other at a speed of ‘u’ and ‘v’ respectively to cross each other?

Explanation

• The Question will contain two trains and its lengths as: ‘a’ of the first train and ‘b’ of the second train.
• The speed of the trains will also be included  as ‘u’ as speed of the first train and ‘v’ as the speed of the second train

If the speed is given in terms of Km/hr, always remember to convert it to m/sec which is done by             this formula

For train 1: =u x (5/18) m/sec and

For train 2: = v x (5/18) m/sec

Or

= (u+v) x (5/18) m/sec

• Now you have find out the time taken by the trains to cross each other; use this formula

= (a+b)/ (u-v)

u-v is called as relative speed of trains travelling in opposite direction

Question 5

What is the time taken by the two trains that start at their points: A for the first train and B for the second train that travels at a speed of ‘u’ and ‘v’ respectively to reach their destination after crossing each other?

Explanation

• The Question will contain two trains and its’ Speed as: ‘u’ of the first train and ‘v’ of the second train.
• You have to find out the time taken by the trains to reach their destination after crossing each other. Use this formula

(√v: √u)

## Tips for Solving Aptitude Questions for Placement and Competitive Exams:

Objective of this article:“Learn the secrets behind solving aptitude easily, explained how from my experience”.

Many people find it hard to solve aptitude and get disappointed when they score less.  So here is a guidance for everyone who find aptitude tough. This article is written based upon my experience.

Here are some reasons why some of us feel aptitude hard:

1. Fear of mathematics.
2. Weak in basics of maths.
3. Lack of practice.

• Learn the basics of math. If you have good math basics of the topics covered till your 12th then consider you are all set to start practicing for your aptitude exam.
• Always remember the basic formula. Example:  Formulae like (a+b)2=a2+b2+2ab, etc. Such formulae are important so memorize them.
• Along with the formula also learn the logical concept behind it, because one question may be asked in different ways so knowing the concept is important.
• Be perfect with tables from 1 to 20. If you don’t know then start practicing now. It is important because they help you do the multiplication part very fast. In most of the problems the multiplication part includes only tables from 1 to 20.
• Solve as many as papers you can. The more you practice the faster you can solve the problems. You can get papers from website and books.
• If you’re weak in some topic don’t try to escape hang to it and keep practicing till you get perfect that will make you at it.
• Do the sums with concentration. Read the question carefully and clearly, there will be a lot of unwanted information in the question, ignore such things. They are just given to confuse you.
• Do the sums with confidence and at the same time don’t over look things with your over confidence.
• Many of the questions will be very easy. So, when you get answer easily don’t think that “this may be the answer”.
• Avoid using paper and pen for small calculations. Using pen and paper for every small question may consume your time.
• During examination do all the sums which you are good at, later solve the sums which are tough and take time.
• Don’t study anything new just before your examination. Go to the hall peacefully.
• If there is negative marking, then  answer only those questions for which you know the answer for sure.

If you follow all these guide lines, I’m sure you’ll score good marks in your test. All the best!
