Observe the table below and answer the following question:

Year	Population	Consumption of electricity (GW)
2015	20	25
2016	30	40
2017	40	60
2018	50	80
2019	60	100

1 GW = 100 Million Watt

Population in Million

Which of the following is true with regards to consumption of electricity per person based on the figures given in the table above?

Correct option is C

Formula Used:
​$$\text{Electricity consumption per person} = \frac{\text{Total Consumption (in Watt)}}{\text{Population (in number)}}$$​​
Since:
1 GW = 100 × 10⁶ Watt
Population is in millions, i.e., 10⁶
Solution:
​$$\begin{aligned}\text{2015:} & \quad \frac{25 \times 100}{20} = 125 \text{ Watts} \\\text{2016:} & \quad \frac{40 \times 100}{30} \approx 133.33 \text{ Watts} \\\text{2017:} & \quad \frac{60 \times 100}{40} = 150 \text{ Watts} \\\text{2018:} & \quad \frac{80 \times 100}{50} = 160 \text{ Watts} \\\text{2019:} & \quad \frac{100 \times 100}{60} \approx 166.67 \text{ Watts}\end{aligned}$$​​
Conclusion:
Electricity consumption per person increased steadily every year from 2015 to 2019.
