**New Math Tricks**, we have already discussed the

**time Speed and Distance aptitude tricks**and told you that

**Time speed and distance**can be divided into several topics. Firstly, we have discussed the boat and streams aptitude. Today we are going to tell you about the

**problems on Trains**. Problems on

**boat and stream**and

**problems on trains**are both subtopics of

**time speed and distance aptitude**chapter.

Problems on trains aptitude tricks concept

⇨When a train crosses a telephone pole, a tree or a man, then it covers its own distance. Crossing a platform or a bridge by a train means it covers it's own length with the object length (Train+platfrom).

⇨ When two trains pass while running in the same or opposite direction then we have to find

**relative speed**.

__Relative speed 1:__when both trains run in the opposite direction, then we calculate it by adding both speeds.

__Relative speed 2:__We subtract lower rate from higher speed while both trains running in the same direction.

**Shortcuts formula for the problems on trains aptitude**:

Formulas For the

**Problems on trains**sections is also same as

**time Speed and Distance**arithmetics math section. We have already covered in the 1st tutorial of

**time speed and distance chapter**, If you have not visited before, please visit

**Time and Speed Distance**chapter before discussing the

**problems on trains math tricks**. Here we need an update with few Shortcuts method with that section.

Aptitude shortcut formula, Question, and quicker solution:

**Aptitude Shortcut Formula1:**

When a train L1 m and L2 m long two platforms have crossed by T1 and T2 sec, respectively. Where L1 is small than L2.

➧The length of the train will be:-

Please note that here L and T is the variable of length and time respectively.

➧The Speed Of The Train will be
