Since the number $$\frac{1}{N}$$ is negative $$N$$ must be negative.

So we have points A and B which are possible.

Since the figure is drawn to scale. Then the point $$\frac{1}{N}$$ is more that $$-0.5$$. The N must be greater that 2.

So only option that fits is A.

Isn't 1/N actually greater than -0.5? (as per direction) so wouldn't N be on the right of 1/N?

You are right. $$\frac{1}{N}$$ is more than $$-0.5$$. The absolute value of $$\frac{1}{N}$$ is less than 0.5.
