It is given that, 15% of A > 20% of B.
⇒ A > 43B.
Now, nothing has been specified about the signs of A and B, so, let us analyze different cases.
Case I:
If A is positive and B is positive.
So, A > 43B is possible only when A > B.
Case II:
If A is positive and B is negative.
A > 43B in all the cases.
Hence, the product of A and B will be negative, i.e., AB < 0.
Case III:
If A is negative and B is positive.
Here, A can never be greater than 43B.
So, this case is not possible.
Case IV:
If A is negative and B is also negative.
Now, A > 43B is possible only when A < B or A = B.
Answers: A, B, C, and D.
⇒ A > 43B.
