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.

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) 42.86
(2) 14.29
(3) 57.14
(4) 75.00

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) -20%
(3) -30%
(4) -10%

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) 450 mm
(4) 367 mm

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) 475 mm
(2) 505 mm
(3) 525 mm
(4) 490 mm

A large store has only three departments, Clothing, Produce, and Electronics. The following figure shows the percentages of revenue and cost from the three departments for the years 2016, 2017 and 2018. The dotted lines depict percentage levels. So for example, in 2016, 50% of store's revenue came from its Electronics department while 40% of its costs were incurred in the Produce department.

In this setup, Profit is computed as (Revenue – Cost) and Percentage Profit as Profit/Cost × 100%.

It is known that

1. The percentage profit for the store in 2016 was 100%.
2. The store’s revenue doubled from 2016 to 2017, and its cost doubled from 2016 to 2018.
3. There was no profit from the Electronics department in 2017.
4. In 2018, the revenue from the Clothing department was the same as the cost incurred in the Produce department.

5) What was the percentage profit of the store in 2018?

Answer:

6) What was the ratio of revenue generated from the Produce department in 2017 to that in 2018?

(1) 8 : 5
(2) 4 : 3
(3) 16 : 9
(4) 9 : 16

7) What percentage of the total profits for the store in 2016 was from the Electronics department?

Answer:

8) What was the approximate difference in profit percentages of the store in 2017 and 2018?

(1) 15.5
(2) 33.3
(3) 8.3
(4) 25.0

Five vendors are being considered for a service. The evaluation committee evaluated each vendor on six aspects – Cost, Customer Service, Features, Quality, Reach, and Reliability. Each of these evaluations are on a scale of 0 (worst) to 100 (perfect). The evaluation scores on these aspects are shown in the radar chart. For example, Vendor 1 obtains a score of 52 on Reliability, Vendor 2 obtains a score of 45 on Features and Vendor 3 obtains a score of 90 on Cost.

9) On which aspect is the median score of the five vendors the least?

(1) Reliability
(2) Customer Service
(3) Quality
(4) Cost

10) A vendor's final score is the average of their scores on all six aspects. Which vendor has the highest final score?

(1) Vendor 2
(2) Vendor 3
(3) Vendor 4
(4) Vendor 1

11) List of all the vendors who are among the top two scorers on the maximum number of aspects is:

(1) Vendor 1 and Vendor 2
(2) Vendor 2 and Vendor 5
(3) Vendor 1 and Vendor 5
(4) Vendor 2, Vendor 3 and Vendor 4

12) List of all the vendors who are among the top three vendors on all six aspects is:

(1) None of the Vendors
(2) Vendor 1
(3) Vendor 1 and Vendor 3
(4) Vendor 3
