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

What was the total number of units (in thousands) of all four products sold in 2022?

• A. 90
• B. 95
• C. 100
• D. 110

Hint:

Read the 2022 row of the table for all four products and add the values in convenient pairs to avoid an arithmetic slip.

Answer 1

The Correct Option is C

Step 1: Instead of adding all four 2022 values left to right in one line, group them into convenient pairs to reduce the chance of an arithmetic slip.
Step 2: From the table, the 2022 sales figures are P $=25$, Q $=35$, R $=20$, S $=20$ (in thousands of units).
Step 3: Pair P with Q: $25+35=60$. Pair R with S: $20+20=40$.
Step 4: Add the two partial sums: $60+40=100$.
Step 5: So the total units of all four products sold in 2022 is $100$ thousand units. \[\boxed{100}\]
