Passage
The following table gives the installed capacity of electricity in gigawatts from solar, wind and coal, along with the population, for two states X and Y in the years 2011 and 2021. In State X the figures are: in 2011 solar 20, wind 10 and coal 40, with a population of 50 million; in 2021 solar 28, wind 15 and coal 42, with a population of 60 million. In State Y the figures are: in 2011 solar 15, wind 8 and coal 50, with a population of 60 million; in 2021 solar 20, wind 10 and coal 55, with a population of 68 million. Based on the data in the table, answer the questions that follow.
What was the per capita availability of electricity in State X in the year 2021?
AAbout 1.21 kW
BAbout 1.41 kW ✓ Correct
CAbout 1.25 kW
DAbout 1.62 kW
Correct answer: (B) About 1.41 kW — The per capita availability is about 1.41 kW, so the answer is about 1.41 kW.
Explanation
★The per capita availability is about 1.41 kW, so the answer is about 1.41 kW.
★In 2021 State X had solar 28, wind 15 and coal 42.
★So its total installed capacity is 85 gigawatts.
★Its population in 2021 was 60 million.
★Per capita availability is the total capacity divided by the population.
★So it is 85 gigawatts over 60 million, which is about 1.41 kW.
★So the answer is about 1.41 kW.
