Study the bar graph which show the imports and exports (in Rs.) of steel of a country during 2013 to 2017 and answer the question that follows. For how many year(s) were the imports less than 80% of the average exports (per year) of the country during the five years? Correct Answer 2

Calculation:

Total exports in the five years = 400 + 450 + 600 + 440 + 650 = 2540

Average export per year = 2540/5 = 508

80% of the Average export = 80% of 508 = 406.4

So we can see that in the years 2013 and 2014 the imports are 330 and 360 i.e below 406.4

∴ In 2 years the imports were less than 80% of the average exports
