SSC GD 2025 PYQ — Question 47

The correct answer is option 2, i.e., xy = k.

Let x and y be inversely proportional.

By definition, inversely proportional means:

When one quantity increases, the other decreases in such a way that their product remains constant.

So, x × y = k (where k is a constant)

1. $x\over{y}$ = k → Incorrect, this is for direct proportionality, not inverse.

2. xy = k → Correct.

3. xy = $y\over{x}$ → Incorrect, does not represent inverse proportionality.

4. $x\over{y}$ = 1 → Incorrect, only true if x = y, not general.
