Study the table and answer the question that follows.
Production of grains in Indian States (in lakh tonnes)

Which state has maximum percentage change in the production of grains between the year 2015 and 2018?

Correct option is C

Solution:

Percentage Change = $$\frac{\text{Production in 2018} - \text{Production in 2015}}{\text{Production in 2015}} \times 100$$​​

Calculating the percentage change in grain production for each state:

- Maharashtra: Percentage change =  $$\frac{150 - 120}{120} \times 100 = 25.00\%$$​​

- Karnataka: Percentage change = $$\frac{90 - 115}{115} \times 100 = -21.74\%$$​​

- Himachal Pradesh: Percentage change =  $$\frac{95 - 125}{125} \times 100 = -24.00\%$$​​

- Kerala: Percentage change = $$\frac{65 - 85}{85} \times 100 = -23.53\%$$​​

- Tamil Nadu: Percentage change = $$\frac{115 - 90}{90} \times 100 = 27.78\%$$​​

Conclusion: The state with the maximum percentage change in the production of grains between 2015 and 2018 is:

- Tamil Nadu with a change of 27.78%
