The most illogical and stupid questions asked in the JEE Mains

JEE Mains is an all India level Engineering Entrance Exam conducted by the CBSE for admission into National Institute of Technology (NITs), Indian Institute of Information Technology (IIITs), and other centrally funded Engineering colleges. Due to the vastness of syllabus and the level of competition, it is considered as one of the toughest engineering entrance examination at the undergraduate level.  But sometimes it proves to be hilarious and full of stupidity. Today we are thus going to tell you some of the most illogical (stupidest) question asked in the JEE Mains.

Question: Which polymer is used in the manufacture of paints and lacquers?

The options given were as follows:-

  1. Glyptal
  2. Polypropene
  3. bakelite
  4. PVC

 Here’s what’s illogical in this question.

 This question was asked in JEE Mains 2015. This question is completely based on the informative part and nowhere tests our aptitude skills. The question was framed from a table which had listed all the polymers and their uses under the chapter of polymers.

Though, some students did apply a bit of logic and had gone with the Bakelite option as it was the only polymer which had the properties required for paints etc. Glyptal came out of nowhere. The “Glyptal” polymer just has a single mention in the entire chapter and that under an informative table.  Putting up a complete factual question from a such an unimportant chapter seems illogical.




Question: The concentration of fluoride, lead, nitrate and iron in a water sample from an underground lake was found to be 1000 ppb, 40 ppb, 100 ppm and 0.2 ppm, respectively. This water is unsuitable for drinking due to high concentration of :

The options given were as follows:-

  1. Fluoride
  2. Lead
  3. Nitrate
  4. Iron

Here’s what’s illogical in this question.

 This question was asked in JEE Mains 2016.Now this question require us to mug up outdated safety limit values of these elements/compounds in water, which is given in a small corner of NCERT book. I really don’t understand what they were thinking while forming this question. There is no logic in asking such a question. But when the exam conducting body is CBSE, then you can expect the unexpected.

Question: Which of the following is the wrong statement?

 The options given were as follows:-

  1. ONCL and ONO- are not iso-electronic.
  2. O3 molecule is bent.
  3. Ozone is violet-black in solid state.
  4. Ozone is di-magnetic gas.

Here’s what’s illogical in this question.

 This question was asked in JEE Mains 2013. I really don’t understand what they were thinking while forming this question but this question seems to be most idiotic question among all  as every statement is absolutely correct. And it is a single option correct type question.




The hottest region of Bunsen Flame ?

The options given were as follows:-

  1. Outermost region
  2. Midde region 1 (just beneath outermost region)
  3. Middle region 2 (just above innermost region)
  4. Innermost region

 Here’s what’s illogical in this question.

 This question was asked in JEE Mains 2016. This question neither required thinking nor any knowledge.  In fact , every 8th grade student know  that outermost part is the hottest part. Now if they expect +2 students to remember some 8th class concepts that too for entrances then I don’t think there is much left to say.

I don’t like this methodology of JEE Mains , whether they are asking questions from a engineering student or an arts student. I really don’t understand what they were thinking while forming this question. Damn system!
