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.

yes, jeevesh sir is right.. answer will come same by both methods.. u did a little bit mistake, I would suggest u that note these mistakes in a blank paper and keep remember that u will not make these mistakes again... these small small mistakes can deduct ur marks in jam..and if u feel first method is easier then try to do it, as by sketching or graphing, chances of doing mistake is less... hope u will get me.. best regards...
