1. Negative deviation as well as rainfall greater than 900 are Arunachal, Kerala, Meghalaya

Rainfall greater than 900 and positive deviations are Maharashtra, Mizoram, Sikkim, Goa

Hence % = 3/7 x 100 = 42.86

2. As we have a total of 9 states with low monsoon and 5 states with negative deviation among them, the state of assam will have the median value = -10%

3. As We can see that there are 5 states (Asam, WB, Jharkhand, Delhi and Manipur ) with rainfall less than 600 and negative deviation.

So Required Average of states with rainfall less than 600 and negative deviation is (600 + 600 + 400 + 300 + 400)/5 = 460

4. Gujrat in 2018 has rainfall of 600 anad deviation of 25% and 2019 is 20% more than 2009 2009 rainfall is 600/1.2 = 500mm.

As deviation is +25% so average 2009 – 2018 is 600/1.25 = 480

LPA 2019 = (480×10 – 500 + 600 )/10 = 490mm
