Hello everyone,
Is there a clear answer to this question. What is the best way to decide whether a particular question can be solved faster using algebra or using the plugging mechanism
Is there any method apart from these?
Regards,

Here's my advice. When doing practice questions, solve them both ways and become proficient at doing both through repetition. Then, I think, you'll be able to answer the question for yourself on the fly.vishal.pathak wrote:Hello everyone,

Generally ratio and proportion, percentages and number system questions can be more easily solved by substituting the variable with some easily calculable number otherwise algebra is the only option. When not sure and you are in guessing mode, plugging in is the best option available. Hope this helps you. But please note that one must practice to develop the intuition to find the best method to be employed
