The given bar chart shows the production of fertilizers by a company (in 1000 tonnes) over 6 years (from 2010 to 2015). Study the bar chart and answer the question that follows. In which of the following years was the percentage increase in production as compared to the previous year the minimum?

The given bar chart shows the production of fertilizers by a company (in 1000 tonnes) over 6 years (from 2010 to 2015). Study the bar chart and answer the question that follows. In which of the following years was the percentage increase in production as compared to the previous year the minimum? Correct Answer 2012

Calculation: 

For 2013:

Production in the year 2012 = 70

Production in the year 2013 = 90

Production increased = 90 - 70 = 20

% increased = (20/70) × 100

⇒ 28.57% (approx)

 

For 2011:

Production in the year 2010 = 40

Production in the year 2011 = 60

Production increased = 60 - 40 = 20

% increased = (20/40) × 100

⇒ 50%

 

For 2012:

Production in the year 2011 = 60

Production in the year 2012 = 70

Production increased = 70 - 60 = 10

% increased = (10/60) × 100

⇒ 16.67% (approx)

 

For 2015:

Production in the year 2014 = 60

Production in the year 2015 = 80

Production increased = 80 - 60 = 20

% increased = (20/60) × 100

⇒ 33.33% (approx)

So, in 2012 the percentage increase in production compared to the previous year was the minimum.

∴ The correct answer is Option 3.
