If p,q,r be three distinct real numbers, then the value of `(p+q)(q+r)(r+p),` is

If p,q,r are any real number, then

Let p,q r be three statements such that the truth value of (p ^^ q) to (q vv r) is F. Then the truth value of p,q r are respectively :

If, p,q,r are negative distinct real numbers , then the determinant Delta=|(p,q,r),(q,r,p),(r,p,q)| is :

If p and r are positive real numbers,then the quantity (p+r)/(q+r) is

If p, q, r are any real numbers, then (A) max (p, q) lt max (p, q, r) (B) min(p,q) =1/2 (p+q-|p-q|) (C) max (p, q) < min(p, q, r) (D) None of these

If p, q, r are any real numbers, then (A) max (p, q) lt max (p, q, r) (B) min(p,q) =1/2 (p+q-|p-q|) (C) max (p, q) < min(p, q, r) (D) None of these

The incorrect statement is (A) p →q is logically equivalent to ~p ∨ q. (B) If the truth-values of p, q r are T, F, T respectively, then the truth value of (p ∨ q) ∧ (q ∨ r) is T. (C) ~(p ∨ q ∨ r) = ~p ∧ ~q ∧ ~r (D) The truth-value of p ~ (p ∧ q) is always T

If p, q, r are real numbers then:
