Quote:
Which of the following most logically completes the argument?
Yorco and Zortech are two corporations that employ large numbers of full-time workers who are paid by the hour. Publicly available records indicate that Yorco employs roughly the same number of such hourly wage workers as Zortech does but spends a far higher total sum per year on wages for such workers. Therefore, hourly wages must be higher, on average, at Yorco than at Zortech, since _____.
(A) Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages
(B) the work performed by hourly wage workers at Zortech does not require a significantly higher level of skill than the work performed by hourly wage workers at Yorco does
(C) the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech
(D) overtime work, which is paid at a substantially higher rate than work done during the regular work week, is rare at both Yorco and Zortech
(E) the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech

Hi Experts
Can you explain which mathematical equations fits in here?
Ah, if only the Verbal section could be conquered with mathematical formulas! As described in our
CR Guide for Beginners, you have to get used to thinking structurally.
So what's the conclusion here? It's that "hourly wages must be higher, on average, at Yorco than at Zortech." How does the author arrive at that conclusion?
- Yorco employs roughly the same number of full-time hourly wage workers as Zortech does.
- Yorco spends a far higher total sum per year on wages for such workers than Zortech does.
We need something that links these facts to the conclusion. In other words, given that both companies employee the same number of such workers, how can we conclude that the reason Yorco spends more on such workers is that Yorco's hourly wages are higher? What if the employees at Yorco simply work longer hours than employees at Zortech? In that case, Yorco could spend more on such workers each year even though they pay the same wage per hour.
Choice (D) rules out that possibility, thus filling a possible hole in the author's logic.
Sure, we could come up with a couple of math equations, but that's a habit that won't help you much on CR in general.
