actual answer is 2.15 but i kept 2 whether the answer is right or wrong in integer type
Sampath, the questions asked in JEE Mains were numerical type and not integer type, to be precise. In integer type questions, the answer would not have any fractional value whereas in numerical type questions, you can have decimal or fraction in your answers. According to this year's guidelines, you are supposed to answer till 2 decimal points precisely. So your answer would be marked as wrong.
