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.

see , in place of 9 if there is 6 ( 6 also satisfying equation 2) , then we are getting fractional that's why they have taken 9 to reduce fractional
it might clear your doubt
sir, so cant fractional solution be there ...ya fir less complication ke fraction nai liya gaya hai...
here all things are in integers...so fraction is not allowed
that's why they smartly take with 9
if any doubt feel free to ask
thanks sir..i got my doubt cleared....
