Discrete Mathematics Propositional Logic GATE PYQs Part-2.

GATE PYQs continued for Discrete Mathematics Propositional Logic. Arranged by Dr. Nitisha Aggarwal(B.E.(I.T.), M.TECH.(CSE),Ph.D.(CSE) here is the solutions to the following GATE questions. GATE CSE 2021 SET-1Q-6. Let p and q be two propositions. Consider the following two formulae in propositional logic.S1:(¬p∧(p∨q))→q S2:q→(¬p∧(p∨q)) Which one of the following choices is correct? GATE CSE 2017 SET-2 Q-7. Let p, q, r denote the statements "It is raining ," It is cold", and " It is pleasant," respectively. Then the statement "It is not raining and it is pleasant, and it is not pleasant only if it is raining and it is cold" is represented by GATE CSE 2017 SET-1 Q-8. Let p, q, and r be propositions and the expression (p→q)→r be a contradiction. Then, the expression (r→p) →q is GATE CSE 2017 SET-1Q-9. The statement (¬𝑝)⇒(¬𝑞) is logically equivalent to which of the statements below?I. 𝑝⇒𝑞II. 𝑞⇒𝑝III. (¬𝑞)∨𝑝IV. (¬𝑝)∨𝑞
