Company X and Company Y are in the business of manufacturing memory cards. Company X sells twice as many memory cards as does Company Y and Company X also has fewer employees than Company Y does. So Company X must be making more profits than Company Y.

Which of the following options best helps to evaluate the argument?

(A) Whether there are any other companies that manufacture memory cards in addition to Company X and Company Y.

(B) Whether both the companies pay similar average salaries to their employees.

(C) Whether Company X will be able to sustain its high sales in the future.

(D) Whether the memory cards of the two companies have similar storage capacities.

(E) Whether Company X is likely to hire more employees in the near future.


There are two companies X and Y and both sell memory cards. The quantity of memory cards sold by companies X and Y are 2a and a respectively.

Let the number of employees in companies X and Y are b and 3b respectively.

So, it’s finally concluded that Company X makes more profit than company Y.

(A) Whether there are any other companies that manufacture memory cards in addition to Company X and Company Y.

Option A is wrong because - even if there is another company which manufactures, their sales volume or market share is the factor which is gonna affect the profits of both companies. This cannot be used as a factor to make a comparison of profits between company X and company Y.

(B) Whether both the companies pay similar average salaries to their employees.

Given the facts, if the companies pay similar average salaries. Then the profit of company X is higher compared to Company Y, provided the sales price is same for both the companies.

(C) Whether Company X will be able to sustain its high sales in the future.

Option C is wrong, as high sales may or may not affect the profit.

(D) Whether the memory cards of the two companies have similar storage capacities.

Storage capacities is not relevant to the question. Hence, wrong.

(E) Whether Company X is likely to hire more employees in the near future.

Option E is wrong - if company X can hire more employees, their expenses can increase. The profits may or may not increase.

Option B

(D) Whether the memory cards of the two companies have similar storage capacities.

(E) Whether Company X is likely to hire more employees in the near future.


Official Explanation



The Conclusion

Company X must be making more profits than Company Y.

The Evidence

Company X sells many more memory cards than does Company Y. Also, Company X has fewer employees (so, its overall salary cost will be lower than that for Company Y).

The Assumption

For this question, one can come up with several assumptions as follows:

• The selling price of the memory cards of the two companies is the same.
• The salaries that the two companies pay to their employees is the same.
• Company X does not incur any extra expenditure on advertising, sales promotion, etc.

So the knowledge of any of the above listed points will make it easier for us to evaluate the given argument. B points out one of these (the average salaries at the two companies) and should be the correct answer.

Let’s also look at the other options:

(A) The conclusion only talks about the relative position of Company X with reference to Company Y. The existence of other companies (who could be better or worse than these two) is irrelevant.

(B) The correct answer.

(C) The conclusion talks about the present so what may happen in the future is irrelevant.

(D) The storage capacities of the memory cards do not matter because the final sales figure will not change because of this fact.

(E) Like option C, the conclusion talks about the present, so what may happen in the future is irrelevant.
