Detailed Solution for Test: Mathematical Reasoning- 1 - Question 13

Let p,q and r be three propositions given by
p:x=5; q:y=−2 and r:x−2y=9
Then, the given statement is (p∧q)→r
Its contrapositive is Test: Mathematical Reasoning- 1 - Question 14

Let p and q be two propositions. Then, the contrapositive of the implication p→q is

Test: Mathematical Reasoning- 1 - Question 15

*Multiple options can be correct
Test: Mathematical Reasoning- 1 - Question 19

Let p and q be two propositions. Then the implication p↔∼q is true ,when

Detailed Solution for Test: Mathematical Reasoning- 1 - Question 19

Explanation:- (p↔∼q) will be true

if both p and ∼q are true ⟹p is true and q is false

Or if both p and ∼q are true ⟹p is false and q is true
