Gce Model Questions Vol1 2017 Economics Question 26
Practice objective / multiple choice question 26 from the 2017 Gce Model Questions Vol1 Economics examination.
A country's population was 20 million in 2010. From 2010 to 2015 it grew at a constant annual compound rate of \(2.5\%\). From 2015 onward the annual growth rate fell linearly each year, reaching \(1\%\) in 2020. Assuming the decline is uniform over the five years 2015‑2020, calculate the population at the end of 2020 (to one decimal place in millions). In 2010 the country had exactly enough arable land to meet its food needs, where each person required 2500\,kcal per day and each kilocalorie of food needed \(0.0005\) hectares of land. How many additional hectares of land are required in 2020 compared with 2010? Give your answer in billions of hectares, to two decimal places.
