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 (Production and Exports in million kg). Consumption = Production - Exports.

Reading the chart: Exports (2006-2010) = 120, 120, 130, 120, 80 million kg. Consumption (2006-2010) = 72.5, 88, 108, 105, 127 million kg.

The ratio of exports to consumption in the given period was the highest in the year

Question

The monthly salary for a person who follows the same expense pattern, but has a petrol expense of Rs 500 p.m., is:

Answer 1

Instead of computing every ratio precisely, a quick comparison of exports against consumption for each year shows the pattern clearly.

In 2006, exports (120) are close to double the consumption (72.5), a very high ratio.
In 2007, exports (120) are still more than consumption (88), but by a smaller margin.
By 2008 and 2009, exports (130, 120) are only slightly above consumption (108, 105), so the ratio keeps shrinking toward 1.
By 2010, exports (80) are well below consumption (127), giving a ratio under 1.

The gap between exports and consumption is largest, relatively speaking, in 2006, giving it the highest ratio.

So the correct answer is option A, 2006.

Answer 2

Instead of computing every ratio precisely, a quick comparison of exports against consumption for each year shows the pattern clearly.

In 2006, exports (120) are close to double the consumption (72.5), a very high ratio.
In 2007, exports (120) are still more than consumption (88), but by a smaller margin.
By 2008 and 2009, exports (130, 120) are only slightly above consumption (108, 105), so the ratio keeps shrinking toward 1.
By 2010, exports (80) are well below consumption (127), giving a ratio under 1.

The gap between exports and consumption is largest, relatively speaking, in 2006, giving it the highest ratio.

So the correct answer is option A, 2006.
