:. Hourly wages must be higher on average at Yorco than Zortech...

A. Zortech spends a higher total sum per year than Yorco does to provide its hourly wage workers with benefits other than wages
Spending on benefits is a different topic... The concern is spending on wages... OUT!

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
Skills are not the issue... OUT!

C. the proportion of all company employees who are hourly wage workers is significantly greater at Yorco than it is at Zortech
The other types of employees is out of scopre... OUT!

Thus far, it's quite easy to eliminate A, B and C...

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
The argument knows that total sums spent by Yorco is greater than Zortech and jumps into conclusion that average is higher in Yorco.. We know that to conclude about average - we must know two components: (1) total sum and (2) total hours... If the hours of workers in Yorco are higher then that will explain the increase in total sums spent and not necessarily mean average is higher...

E. the highest hourly wages paid at Yorco are higher than the highest hourly wages paid at Zortech
The conclusion is about the average hourly wage... The breakdown of the total sums that contributed to the average is not known...

Answer: D


but the argument doesn't say that the overtime hours are same. It only says that Overtime hours are rare at both corporations, but what if in Zortech it is more rare then in Yorco?

D is the correct answer

Conclusion - hourly wages must be higher, on average, at Yorco than at Zortech

Premise - Yarco spends a far higher total sum per year on wages for such workers than Zortech

The logical explanation must cover the above 2 pointers and must be a supporting reason for conlusion

A opposes the argument
B talks about skills
C does not matter. The group under study is hourly wage workers
E does not talk about averages

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.
