Directions : Question numbers 33 and 34 are based on the following information :
Number of working days annually :
Year / Employee A B C D E 2018 280 310 315 315 320 2019 300 290 310 315 325 2020 310 300 315 310 320 2021 315 310 315 310 330 2022 295 300 300 305 310
| Year / Employee | A | B | C | D | E |
|---|---|---|---|---|---|
| 2018 | 280 | 310 | 315 | 315 | 320 |
| 2019 | 300 | 290 | 310 | 315 | 325 |
| 2020 | 310 | 300 | 315 | 310 | 320 |
| 2021 | 315 | 310 | 315 | 310 | 330 |
| 2022 | 295 | 300 | 300 | 305 | 310 |
E
The question spans all five years, so each employee's column has to be totalled down the table.
A: \(280 + 300 + 310 + 315 + 295 = 1500\).
B: \(310 + 290 + 300 + 310 + 300 = 1510\).
C: \(315 + 310 + 315 + 315 + 300 = 1555\).
D: \(315 + 315 + 310 + 310 + 305 = 1555\).
E: \(320 + 325 + 320 + 330 + 310 = 1605\).
Comparing the five totals, 1605 is the largest, and it belongs to E. The reading is confirmed by the rows themselves, since E records the highest figure in every one of the five years, so no other column could overtake it.
Hence the employee with the maximum working days during 2018-2022 is E.
C and D
The five column totals over 2018-2022 are needed again, so compute each one.
A: \(280 + 300 + 310 + 315 + 295 = 1500\).
B: \(310 + 290 + 300 + 310 + 300 = 1510\).
C: \(315 + 310 + 315 + 315 + 300 = 1555\).
D: \(315 + 315 + 310 + 310 + 305 = 1555\).
E: \(320 + 325 + 320 + 330 + 310 = 1605\).
Scanning the totals for a repeated value, only C and D match, both standing at 1555. Note that they reach the same total by different routes — C works more days in 2019 while D works more in 2018 and 2022 — so the equality shows up only after the columns are summed and cannot be spotted row by row.
The other combinations fail: A and B differ by 10, and B and D differ by 45.
Hence the employees with equal total working days are C and D.
