Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Well i think this question is incorrect... As this one came in bhu bsc entrance exam in 2018 and as i have seen this question that time.... So it seems to be wrong and most probably the power of (1+x) should be 1/x rather than 1/2..
