The table below provides details of the revenue and expenses (in USD) incurred by six companies (A to F) over a three-year period: 2011, 2012, and 2013. Profit or loss is calculated as Revenue - Expenses.

YearYear 2011Year 2012Year 2013
CompanyRevenueExpensesRevenueExpensesRevenueExpenses
A50,00040,00075,00060,00060,00080,000
B60,00050,00070,00070,000100,00080,000

F40,00020,00050,00060,00090,00050,000


For each of the following statements, select Yes if the statement is true based on the information provided. Otherwise, select No.
­

Official Solution:


Statement 1:

To evaluate this statement, we need to compare revenue and expenses for each company over the three-year period. Upon review, we can see that Company B did not incur a loss in any of the years—it broke even in 2012 and made a profit in both 2011 and 2013. Therefore, this statement is not true.

Statement 2:

The highest profit as a percentage of expenses essentially means the highest revenue-to-expenses ratio. The highest ratio in 2013 was for Company F: 90,000/50,000 = 1.8 (80% profit). Let's check if any company in 2011 or 2012 had a higher revenue-to-expenses ratio. Quickly scanning the data, we can see that in 2011, Company F had an even higher ratio: 40,000/20,000 = 2, indicating a profit of 100%. Therefore, this statement is not true.

Statement 3:

Companies A, C, D, E, and F experienced a loss in at least one year, while Company B broke even in 2012, meaning it did not incur a profit either. Therefore, this statement is true.


Correct answer:

Each company incurred a loss in at least one of the three years. "No"

The highest profit as a percentage of expenses incurred by any company was in 2013. "No"

Each company did not incur a profit for at least one of the three years. "Yes"

You're correct that we're comparing \(\frac{Profit}{Expenses}\). However, we can simplify as \(\frac{Profit}{Expenses} = \frac{Revenue - Expenses}{Expenses} = \frac{Revenue}{Expenses} - 1\), which is the same as comparing just the ratio between revenue and expenses.

I hope that helped!
