What is the most mind boggling Maths question asked in JEE?
Here’s an answer by one Abhilash Kumar:
Every one will surely agree with me that this list is really a big one.
Some them which i remember are:
1>>This question was asked in JEE 1999.Its a multiple option correct question.I later found that this one was closely related to a question asked in IMO few yeas back form then.
2>>This question was asked in JEE Main 2005. It was really difficult for my maths teacher at FIITJEE to make us understand the solution.(A class ,later whose students’s average rank was less than 1000 in JEE).
Now what i remember are two paragraph based questions one asked in JEE 2009 and other one in the following year.Both questions were from matrices and determinant ,which are considered to be the easiest topic during the time of JEE preparation.
People who appeared for JEE 2009 must have suffered lot of pain solving this paragraph i suppose.The problem would have been to decide this.
>>How can you leave 3 questions = 12 marks (that’s a lot in JEE) on the other hand how can you devote so much time in 3 hours exam solving them 😉 .
The paragraph based question that came up the following year was even more mind-boggling.Even coaching institute took long time to give a simple solution.As you might know that after JEE coaching institutes compete each other (not for result 😉 ) , but to produce the solution as fast as possible.
In the 1st question option are:
>>a. a(100)<=100…. and so on..brackets are missing in the options.
