The production in 2017 was approximately what percent of the average production over the given years?

Answer: B

Correct answer: 98%

First find the average over the five years.

\[120 + 130 + 125 + 140 + 145 = 660 \text{ million tonnes}\]

\[\text{Average} = \frac{660}{5} = 132\]

The 2017 figure is 130, so as a percentage of the average:

\[\frac{130}{132} \times 100 = 98.48\% \approx 98\%\]

2017 sits marginally below the five-year average, which is why the answer is just under 100%.
