Answers and Explanations
Answer 1: (a)
Let the total Workforce = 100.
Workforce in Production = 49.
22% of Production = 22% of 49 = 10.78
So 10.78 workers in Hyderabad are in production department.
Total workforce in Hyderabad = 28
Therefore the percentage = (10.78/28) x 100 = 38.5%
The correct option is (a)
Answer 2: (d)
As percentage of supervisors posted in Calcutta region is not given so data is insufficient. The correct option is (d)
Answer 3: (b)
Total Officers in company is 68700 × 9/100 = 6183
The number of employees in the Administration and Accounts department = 11% of 6183 = 680.13
The number of employees in Administration and Accounts department posted in Calcutta = 75% of 680.13 = 510
So the required percentage = (510/6183) × 100 = 8.25%
The correct option is (b)
Answer 4: (c)
The total workforce at Hyderabad = 28% of 68700 = 19236
The total workforce at Mumbai = 22% of 68700 = 15114
The total workforce at Calcutta = 15% of 68700 = 10305
So the new recruitment = 12% of (19236 + 15114) = 12% of 34350 = 4122
The total retirement = 6% of 10305 = 618.3
Hence the total workforce = 68700 + 4122 – 618.3 = 72203.7 = 72204
The correct option is (c)
