Comparison Problems are Numericals in Physics, wherein a concept in the form of an equation will be applied for two sets of values for the variables given in the equation. The outcome needs to be determined by solving those equations either by simple division / algebraic methods. 

Students commit lots of mistakes in such numericals, and I had made a survey of all those numericals and the result is being presented to you in the below page.

Do watch it and offer your valuable advice to us, so that we can improverise further on it.
