Question

Directions:
Directions for the following 4 questions: The table below shows the sales (in thousands of units) of four products P, Q, R and S of a company over three years. Study the table and answer the questions that follow. Year | P | Q | R | S 2021 | 20 | 30 | 25 | 15 2022 | 25 | 35 | 20 | 20 2023 | 30 | 40 | 30 | 25

Which product had the highest total sales over the three years combined?

• A. Q
• B. P
• C. R
• D. S

Hint:

Instead of totaling all three years for every product, check whether one product's sales value is the largest in every single year - that product's overall total must then be the largest too.

Answer 1

The Correct Option is A

Step 1: Instead of computing each product's three-year sum, compare the products year by year to spot which one dominates consistently.
Step 2: Look at each year's row: in 2021, sales are P $=20$, Q $=30$, R $=25$, S $=15$ - Q is already the highest.
Step 3: In 2022, sales are P $=25$, Q $=35$, R $=20$, S $=20$ - Q is again the highest.
Step 4: In 2023, sales are P $=30$, Q $=40$, R $=30$, S $=25$ - Q is once more the highest.
Step 5: Since Q has the strictly highest sales figure in every single year compared to every other product, its three-year total must also be the highest of all four products, without needing to add up every column. \[\boxed{Q}\] Correct option: Q
