The following chart shows the production of an organization in various years from 2012 to 2016. Study the chart and answer the question.

What was the percentage increase in the production from 2015 to 2016?

Given: 

Production in 2015 = 12.6 tons 

Production in 2016 = 18.9 tons

Formula Used: 

Increased in production % = $$\frac{ \text{ Increase}}{\text{Production in previous year}} \times 100$$ 

Solution: 

Increase = 18.9 - 12.6 = 6.3 

Increase % = $$\frac{6.3}{12.6} \times 100 = 50\%$$ 

Thus, Percentage increase from 2015 to 2016 is 50 %.
