I think the ans is D

x can be either >3 or <-3 but if the x is positive then it will satisfy the condition in statement 1
similarly x can be either >5 or <-1 but if x is positive then it will satisfy the condition in the statement 2.

What is the OA and its explanation?

How does one solve for such problems?

I get x^2 - 2x - 3 >0
which gives
x>-1
x>3
as the solution

statement 2 i get

x^2 - 4x - 5 >0
which gives
x>-1
x>5

study you are right
My bad,
for statement 1, the values x>3 and x<-1 satisfies the condition
similarly for statement 2, the values x>5 and x<-1 satisfies the condition.
But as it is mentioned x is positive we see in both satements the value of x comes out more than 3.
So each statement is sufficient. D
