Study the table and answer the question that follows.

In which state was the annual rainfall (in cm) for 2005 greater than the average annual rainfall (in cm) for all three years?

Correct option is B

Solution:

Calculate the average annual rainfall for each state over the three years (2000, 2005, 2015):

- Himachal Pradesh: Average rainfall = $$\frac{110 + 90 + 150}{3} = 116.67 cm$$​​

- Uttar Pradesh: Average rainfall =  $$\frac{120 + 85 + 90}{3} = 98.33 cm$$​​

- Madhya Pradesh: Average rainfall = $$\frac{90 + 65 + 80}{3} = 78.33 cm$$​​

- Andhra Pradesh: Average rainfall = $$\frac{55 + 75 + 65}{3} = 65.00 cm$$​​

- Tamil Nadu: Average rainfall = $$\frac{150 + 90 + 115}{3} = 118.33 cm$$​​

Compare the 2005 rainfall to the calculated average for each state:

- In Himachal Pradesh, the rainfall in 2005 (90 cm) is not greater than the average rainfall (116.67 cm).

- In Uttar Pradesh, the rainfall in 2005 (85 cm) is not greater than the average rainfall (98.33 cm).

- In Madhya Pradesh, the rainfall in 2005 (65 cm) is not greater than the average rainfall (78.33 cm).

- In Andhra Pradesh, the rainfall in 2005 (75 cm) is greater than the average rainfall (65.00 cm).

- In Tamil Nadu, the rainfall in 2005 (90 cm) is not greater than the average rainfall (118.33 cm).

Conclusion: The states where the annual rainfall in 2005 was greater than the average rainfall for the three years are:

Andhra Pradesh
