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?
Answer & explanation
Correct answer: option 3
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.
