CAT 2019 LRDI Questions with Answers 14

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.

Question 1:
If a ‘Heavy Monsoon State’ is defined as a state with actual rainfall from June-August, 2019 of 900 mm or more, then approximately what percentage of ‘Heavy Monsoon States’ have a negative deviation from respective LPAs in 2019?

1. 14.29
2. 57.14
3. 42.86
4. 75.00

Question 2:
If a ‘Low Monsoon State’ is defined as a state with actual rainfall from June-August,2019 of 750 mm or less, then what is the median ‘deviation from LPA’ (as defined in the Y-axis of the figure) of ‘Low Monsoon States’?

1. $-10 \%$
2. $-30 \%$
3. $-20 \%$
4. $10 \%$

Question 3:
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?

1. 500 mm
2. 460 mm
3. 367 mm
4. 450 mm

Question 4:
The LPA of a state for a year is defined as the average rainfall in the preceding 10 years considering the period of June-August. For example, LPA in 2018 is the average rainfall during 2009-2018 and LPA in 2019 is the average rainfall during 2010-2019. It is also observed that the actual rainfall in Gujarat in 2019 is 20% more than the rainfall in 2009. The LPA of Gujarat in 2019 is closest to

1. $525 \mathrm{mm}$
2. $490 \mathrm{mm}$
3. $475 \mathrm{mm}$
4. $505 \mathrm{mm}$
