Study the table and answer the question that follows.

Which state has the maximum percentage decrease in annual rainfall between the years 2000 and 2015?

Correct option is B

Solution:

To find the state with the maximum percentage decrease in annual rainfall between 2000 and 2015, we use the following formula:

Percentage Decrease = $$\frac{\text{Rainfall in 2000} - \text{Rainfall in 2015}}{\text{Rainfall in 2000}} \times 100$$​​

Calculate the percentage decrease for each state:

Himachal Pradesh: Percentage increase = $$\frac{150 - 110}{110} \times 100 = 36.36\%$$​​

- Uttar Pradesh: Percentage decrease = $$\frac{120 - 90}{120} \times 100 = 25.00\%$$​​

- Madhya Pradesh: Percentage decrease = $$\frac{90 - 80}{90} \times 100 = 11.11\%$$​​

- Andhra Pradesh: Percentage increase = $$\frac{65 - 55}{55} \times 100 = 18.18\%$$​​

- Tamil Nadu: Percentage decrease =  $$\frac{150 - 115}{150} \times 100 = 23.33\%$$​​

Conclusion: The state with the maximum percentage decrease in annual rainfall between 2000 and 2015 is Uttar Pradesh with a decrease of 25.00%.
