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.
