Question

Instructions: The following bar graph gives the production, exports and per-capita consumption of rice in country A, for the five years from 2006 to 2010. Consumption = Production - Exports. Per Capita Consumption = Consumption ÷ Population.

Reading the chart precisely gives this table:
2006: Consumption = 72.5, Per-capita = 36.25, Population = 2.00 million
2007: Consumption = 88, Per-capita = 35.2, Population = 2.5 million
2008: Consumption = 108, Per-capita = 38.7, Population = 2.79 million
2009: Consumption = 105, Per-capita = 40.5, Population = 2.59 million
2010: Consumption = 127, Per-capita = 42, Population = 3.02 million

In which of the given years was the population of country A the highest?

• A. 2007
• B. 2008
• C. 2009
• D. 2010

Hint:

Divide each year’s consumption by its per-capita consumption and compare all five results.

Answer 1

The Correct Option is D

Step 1: Recall the population values.
Using Population \(=\dfrac{\text{Consumption}}{\text{Per Capita Consumption}}\) for each year gives: 2006 ≈ 2.00 million, 2007 ≈ 2.5 million, 2008 ≈ 2.79 million, 2009 ≈ 2.59 million, 2010 ≈ 3.02 million.

Step 2: Compare.
The largest value among these is 3.02 million, in 2010.

Step 3: Final Answer.
The population of country A was highest in 2010, so option D is correct.
