The bar graph shows the production of salt (in lakh tonnes) by three companies A, B and C from 2016 to 2020.
What is the percentage increase in the production of salt by company A in 2020 as compared to 2016?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 50%
A percentage increase is measured on the earlier year's value, here 2016.
Company A: 2016 \(=80\), 2020 \(=120\) lakh tonnes
Increase \(=120-80=40\)
Percentage increase \(\displaystyle=\frac{40}{80}\times100=50\%\)
