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.

I didn't understand this, please explain.
all same so one equations
what about the total number of variables why not 6?
total number of variable 3 alpha beta gama
x1,x2,x3 given variable
sir this is the actual result of dimension, right?
yes ax1+bx2+cx3=0 => ax1=-bx2-cx3 here a depands on b and c or b and c independent variables so dim 2
but a,b,c are the constants and not the variables.
aplha,beta gama elements of vector of Y not constant
par sir dimension= number of independent variables so answer should be 3?
a+2b+3c=0 then a depands -2b-3c independent b,c
