If A={p,q,r} and B={q,p,r}. Then check whether A=B or not.

Consider the sets A ={p,q,r,s} and B={1,2,3,4}. Are they equal?

Let A = {P, Q, R, S} and B = {1, 2, 3} which of the following relations from A to B is not a function.

If P={a,b,c} and Q={r}, form the sets P xx Q and Q xx P .

If P ={ a, b, c} and Q = {r} , find P xx Q .

If p, q, r are real numbers then:

If p,q,r are in A.P. and are positive, the roots of the quadratic equation px^(2) + qx + r = 0 are real for :

If p, q, and r are proposition with truth values F, T and F respectively, then the truth values of (p ^^ ~q) to r , (p vv q) to r and q to (p ^^ r)

lf r, s, t are prime numbers and p, q are the positive integers such that their LCM of p,q is r^2 t^4 s^2, then the numbers of ordered pair of (p, q) is

Let A= [[a,b,c],[p,q,r],[x,y,z]] and suppose then det (A) = 2, then det (B) equals, where B = [[4x,2a,-p],[4y, 2b, -q],[4z, 2c, -r]]
