A, B, C, D and E are five persons
employed to complete a job X. Line graph shows the data
regarding the time taken by these five persons to complete
the job X individually. Table shows the actual time for
which every one of them worked on the job X.
| Person | Days Worked |

| B | ? |
| C | 3 |
| D | ? |
| E | 2 |
Note 1: All persons worked for whole number of days.
