Study the given chart carefully and answer the question accordingly.

In which of the following years was the percentage increase in production from the previous year, the maximum among the given years?

2011

Lets solve one by one for each option.

1. 2014

Production in 2014 = 1300

Production in 2013 = 900

Increase in production in 2014 from its previous year = \(\frac{1300-900}{900}\) × 100

= \(\frac{400}{900}\) × 100

= 44.44%

2. 2016

Production in 2016 = 1500

Production in 2015 = 1000

Increase in production in 2016 from its previous year = \(\frac{1500-1000}{1000}\) × 100

= \(\frac{500}{1000}\) × 100

= 50%

3. 2011

Production in 2011 = 800

Production in 2010 = 500

Increase in production in 2011 from its previous year = \(\frac{800-500}{500}\) × 100

= \(\frac{300}{500}\) × 100

= 60%

4. 2012

Production in 2012 = 1200

Production in 2011 = 800

Increase in production in 2012 from its previous year = \(\frac{1200-800}{800}\) × 100

= \(\frac{400}{800}\) × 100

= 50%

Increase percentage comparative to previous year is maximum in 2011.
