St1: G - 5 > H - 5 --> Clearly sufficient to prove G > H

St2: 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

Answer: A

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

[A] G-5>H-5
G^2>GH

[b] Statement 1

G-5 > H -5
We can remove 5 from both sides.

G > H.

Statement 1 is sufficient

Statement 2

$$G^2$$>GH

G.G>G.H
G(G-H) > 0

Either G < 0 or G > H

Not sufficient

For statement 2,
G^2>GH

Since no information is given about G, we will consider two cases for G,
1.) When G is +ve, then (G^2)/G>(GH)/G --------> G>H

2.)When G is -ve, then (G^2)/(-G)<(GH)/(-G) ------------> G<H because, when an inequality is divided by a -ve number then sign of inequality changes.

Therefore, statement 2 is insufficient.

Hence, answer will be A.
