from 1: one equation . insufficient
from 2: one equation . insufficient

combining both two equation

Question: Is x>y?

Statement 1: $$x = \frac{7}{91^{25}}$$

No information about y hence
NOT SUFFICIENT

Statement 2: $$y = 13*91^{24}$$

No information about x hence
NOT SUFFICIENT

COmbining the two statements
we have x as well as y hence

SUFFICIENT

Answer: option C

Solution:

We need to find if x is greater than y or not.

Statement-1: “$$x = \frac{7}{91^{25}}$$ “

We need to compare two variable, x and y, and, from this statement, we only have information about x.

Hence, Statement 1 alone is not sufficient to answer the question.

Statement-2: “$$y = 13 * 91^{24}$$ “

We need to compare two variable, x and y, and, from this statement, we only have information about y.

Hence, Statement 2 alone is not sufficient to answer the question.

Combining both the statements:

From statement 1, we have:
• $$x = \frac{7}{91^{25}}$$ which is less than 1.

From statement 2, we have:
• $$y = 13 * 91^{24}$$ which is more than 1.

Thus, x<y.

Hence, we can arrive at the answer by combining both the statements.

Hence, the correct answer is option C.

Answer: C

Answer: C

So irrespective of a value is less <1 or > 1, we dont need to find the value. Why? Because whatever value of x or y is, either the answer is yes or no , and hence for our Yes/No DS, our answer will be C.
