As soon as the ISC Class 12 Mathematics paper is over, we will update you with the unofficial answer key based on the research done by our experts:

Questions	Answer
i) If A is a square matrix of order 3 and its determinant is |A| = 3, then the value of |-4A| is:	b) 192
ii) Consider the function f given by f(x)=log x, x>0, then the function f is:	a) differentiable and continuous at x = 1
