If G > 0; H can be 0 and G(G - H) > 0 --> In this case is G > H? No
Not Sufficient
Answer: A
Hi, thank you for your explanation. Here, the question asks whether G>H
In statement 2, the inequality clearly satisfies this condition. l am not clear why its still insufficient.
Help?
Hi,
I am not able to understand my own explanation for the 2nd statement. I will edit my solution.
Please refer to the below explanation for the 2nd statement:
G^2 - GH > 0
G^2 is positive --> G can be negative or positive
Suppose the value of GH is negative --> If G is positive and H is negative then G > H
If G is negative and H is positive then G < H
Not Sufficient
