A company has two divisions: a food division and a non-food division. While the food division was profitable last year, the non-food division lost money. However, since the food division was bigger, in terms of revenue, than the non-food division, the company as a whole must have been profitable last year.
Which of the following statements about last year, if true, most strengthens the above argument?
A. The food division made more revenue per unit sold than the non-food division.
B. The proportion of revenues generated in the last six months of the year was much greater for the food division than for the non-food division.
C. None of the products sold by the food division were sold at a loss.
D. The food industry was much more profitable last year than it had been the previous year.
E. The profit per dollar of revenue for the food division was equal to the loss per dollar of revenue for the non-food division.
Target Test Prep Official Explanation:The conclusion of this argument is that “the company as a whole must have been profitable last year.”
The support for that conclusion is that the food division was profitable last year and that the food division was bigger, in terms of revenue, than the non-food division.
The correct answer will help to confirm that the conclusion is correct.
(A) The food division made more revenue per unit sold than the non-food division.This choice may appear to help confirm the conclusion, but it actually makes no difference. All this choice indicates is that the prices of items sold by the food division were higher than the prices of items sold by the non-food division.
That information doesn’t indicate anything new about profitability since price alone doesn’t indicate how profitable sales were.
(B) The proportion of revenues generated in the last six months of the year was much greater for the food division than for the non-food division.This choice has no effect on the argument. We already know that, for the year as a whole, the food division was profitable and the food division was bigger, in terms of revenue, than the non-food division.
The information about what occurred in the last six months of the year doesn’t change the support for the conclusion, which is about “last year” as a whole.
(C) None of the products sold by the food division were sold at a loss.This choice may appear to strengthen the argument, but it actually changes nothing. After all, we already know that the food division was profitable, and the fact that none of the products it sold were sold at a loss doesn’t indicate how profitable it was. After all, products not sold at a loss could be sold at breakeven prices or at a very small profit.
(D) The food industry was much more profitable last year than it had been the previous year.This choice presents an irrelevant comparison. The fact that the food industry was more profitable last year than the previous year does not mean that the particular company in question was profitable.
(E) The profit per dollar of revenue for the food division was equal to the loss per dollar of revenue for the non-food division.
Correct AnswerThis choice proves conclusively that the company was profitable last year.
After all, if, as the passage says, the food division generated more revenue than the non-food division and, as this choice says, the profit per dollar of revenue for the food division was equal to the loss per dollar of revenue for the non-food division, then the company must have been profitable. After all, if the food division made as much per dollar of revenue as the non-food division lost and also generated more revenue, then the food division offset all the losses of the non-food division and also made more profits as well.
We can illustrate this idea with a simple example.
Food Division:Revenue - 1000
Profit Per Dollar of Revenue - 30
Total Profit - 300
Non-Food Division:Revenue - 500
Loss Per Dollar of Revenue - 30
Total Loss - 150
So, the food division’s profit of 300 less the non-food division’s loss of 150 leaves a net profit of $150.
