the question in iit jee 2011 does not have consistent data in one of the maths question.
they have given an integral with some f(1)=2 but putting it in the original equation we get 1/3.
though all answers in all solns have been given using the given data.
will this be given as a bonus???
as only u have such problem so i dont think they have any inconsistent data .
So u pls look once again u might have done it wrong
Anyhow no bonus i in JEE
