Annual Rainfall (in cm) in Indian States

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

Formula Used:
$$\text{Average Annual Rainfall} = \frac{\text{Rainfall in 2000} + \text{Rainfall in 2005} + \text{Rainfall in 2015}}{3}$$​​
Solution:
Himachal Pradesh:
Average Rainfall = $$\frac{110 + 90 + 150}{3} = \frac{350}{3} = 116.67 \, \text{cm}$$​​
Rainfall in 2005 = 90 cm (less than 116.67 cm).
Uttar Pradesh:
Average Rainfall = $$\frac{120 + 85 + 90}{3} = \frac{295}{3} = 98.33 \, \text{cm}$$​​
Rainfall in 2005 = 85 cm (less than 98.33 cm).
Madhya Pradesh:
Average Rainfall = $$\frac{90 + 65 + 80}{3} = \frac{235}{3} = 78.33 \, \text{cm}$$​​
Rainfall in 2005 = 65 cm (less than 78.33 cm).
Andhra Pradesh:
Average Rainfall =$$\frac{55 + 75 + 65}{3} = \frac{195}{3} = 65 \, \text{cm}$$​​
Rainfall in 2005 = 75 cm (greater than 65 cm).
Tamil Nadu:
Average Rainfall = $$\frac{150 + 90 + 115}{3} = \frac{355}{3} = 118.33 \, \text{cm}$$​​
Rainfall in 2005 = 90 cm (less than 118.33 cm).
Conclusion:
The only state where the annual rainfall in 2005 was greater than the average annual rainfall across all three years is Andhra Pradesh.
