Timing question

In this question, she draws out the chain for each of the choices. If a similar question were to come on the test, would it still be feasible to test out every answer choice and redraw the chain for each? Wouldn't it take up a lot of time?

This question can be answered by looking at our initial setup, there is no need to draw out of any of the choices, it is done for illustrative purposes only.

> I > F> M > G >J >H
> L > N

We can see that we need to determine where L>N chain fits within the I>F>M>G>J>H chain. L salary alone is insufficient to determine the complete ranking because the rank of N would remain unknown. N > F or N > M only help us to determine the rank of N, but not I & L. N > I is the only option that allows us to definitively join these two chains into K > L > N >I > F> M> G> J>H.

The bottom line is I would not recommend drawing out each of the answer choices on an actual test, your initial setup is sufficient to determine the correct answer here.

Let me know if you have any further questions.

Why would E not be correct?

I'm not understanding how N - I allows you to join the two chains ?
