To compare the rainfall data, India Meteorological Department (IMD) calculated the Long Period Average (LPA) of rainfall during period June-August for each of the 16 states. The figure given below shows the actual rainfall (measured in mm) during June-August, 2019 and the percentage deviations from LPA of respective states in 2018. Each state along with its actual rainfall is presented in the figure.
What is the average rainfall of all states that have actual rainfall of 600 mm or less in 2019 and have a negative deviation from LPA?
Correct Answer :
460 mm
Solution :
First, identify all the states from the given data set that satisfy both conditions:
1. Actual rainfall is less than or equal to 600 mm in 2019.
2. Deviation from LPA is negative.
Once these states are identified, find their actual rainfall values. Calculate the arithmetic mean of these values to find the average rainfall.
