Question

Consider the following three statements:
P : 5 is a prime number.
Q : 7 is a factor of 192.
R : L.C.M. of 5 and 7 is 35.
Then the truth value of which one of thefollowing statements is true ?

• A. $(P\wedge Q)\vee (\sim R)$
• B. $(\sim P)\wedge (\sim Q\wedge R)$
• C. $(\sim P)\vee (Q\wedge R)$
• D. $P\vee (\sim Q\wedge R)$

Answer 1

The correct option is D $P\vee (\sim Q\wedge R)$

P is True

Q is False

R is True

Option 4) $T\vee (T\wedge T)=T$
