Logical puzzles are one of the most interesting set of questions in the CSIR-NET exams. Just like the detective Sherlock Holmes, who solves puzzling questions pertaining to a crime by deducing answers from observations, these questions too demand deducing the correct option from the observations made.
Step 1: Write down all the observations from the given question.
Step 2: Analyse the observations one by one.
Step 3: Eliminate the impossible options for each observation.
Step 4: Continue this process until you weed out three of the options so that you are left with the obvious correct option.
Note that while analysing, there may be some irrelevant observations with respect to the given question. Avoid them to save time.
