Q.5) Does "square matrix of matrix" means square of the matrix? I didn't read in that way. I was reading it as square matrix whose rows are equal to columns. I am not sure exactly what it means over here?

Q.8) As onionknight said, if x>= was not given, then it would have been (A)

Q.14) I think you are correct. Answer should be (d)

Q.18) I just did it by logic. If g1 and g2 are straight lines in third quadrant, then, |f(x*, y*)| > |f(x',y')|
Tell me If I am wrong.

Q.26)Search Gambler's Ruin on Google, you will get the solution. The solution is a bit tedious to write over here. This kind of problem can only be done if you have done similar problems beforehand. During exam, I can't even think of any solution like this.
