Sir kis type ke questions h yeh kya bolte h inko topic kis naam se h ye

[ayushjaiswal]

If P is true then both q and s true.

So it doesn't follow if p is false the both q and s be false

It could be the case as p is false and then q falsd but s true.

Hence reverse case of statement 1 doesn't follow

Hence answer neither 1 nor 2

Kindly review

Conclusion 1...
If T is true then either R or P is false (but P can be false even if S is true ) then this concludes that R and S can be true even if P is false
