| P : 5 is a prime number |
| Q : 7 is a factor of 192 |
| R : L.C.M. of 5 and 7 is 35 |
A) \[(P\wedge Q)\vee (\sim R)\]
B) \[P\vee (\sim Q\wedge R)\]
C) \[(\sim P)\wedge (\sim Q\wedge R)\]
D) \[\left( \sim P \right)\vee \left( Q\wedge R \right)\]
Correct Answer: B
Solution :
P is true Q is false R is true by option \[P\vee \left( \sim Q\wedge R \right)\] \[=\,\,\,\,T\vee \left( T\,\,\wedge \,\,T \right)\] = T
