Question

Using the same bar graph, what is the average production of product R over the three years?

• A. 20
• B. 25
• C. 30
• D. 35

Hint:

For bar graph averages, sum values and divide by the number of periods.

Answer 1

The Correct Option is B

- Step 1: Production of R: 2013 = 20, 2014 = 25, 2015 = 30.
- Step 2: Total = $20 + 25 + 30 = 75$.
- Step 3: Average = $75 \div 3 = 25$.
- Step 4: Verify: $20 + 25 + 30 = 75$, $75 \div 3 = 25$.
- Step 5: Check options: Option (2) is 25, which matches.
- Step 6: Ensure all years included.
