Logical Puzzles

Theory:

These type of questions asked in CSIR NET Paper-I are the simplest amongst all the questions asked by them.

unnamed

Attempt these questions like a detective!!  🙂 Just like Vyomkesh Chandra Bakshi, solve the puzzle by deducing from the observations and visualising scenario in real world.

With the following steps one can be fairly capable of solving logical puzzles asked in these exams.

Step 1: Note all observations from the given question. ( Phew!!)

Step 2: Analyse every noted observation by comparing it with the remaining observations. ( Where do I see a contradiction?? Wooohooo.. Here I see it!!)

Step 3: Eliminate impossible / incorrect observations. (GET OUT.. miss. Misleading option!!)

Step 4: Cross check whether the remaining observation(s) is/(are) suitable. (Finally.. Are you the one I am looking for??? Ummmhmmm… )

Step 5: If correct observation is found, then stop the process .(Hurrraaahhh.. I found  it!! I found it!!.) Else, go back to step 2.(Oh no!!! Where did I go wrong??)
