Part 2 – Train4Aptitude

by Shiva Prasad


Aptitude problems are an important part of competitive examinations. Aptitude Problems on concepts of time, speed, distance manifested either in the form of Problems on trains or stream and boats or simply a generic example involving cars, bicycle etc. The key to solving the problems is effectively visualizing the scenario given, and translating the problem that is described into equations which could then be worked on to solve problems.

Following are this week’s videos to help you train yourself on aptitude.
