A set of eight candidates A, B, C, D, E, F, G and H are being interviewed by two panels of interviewers: Panel I and Panel II-from 9.30 to 10.50 on a particular day. Each panel will spend about 10 minutes per candidate and at no time during the interview process will a panel be without any candidate. The original schedules of interviews for the eight candidates are shown in the following table:
Candidate | Panel-I Time | Panel-II Time |
A | 9.30 to 9.40 | 10.10 to 10.20 |
B | 9.40 to 9.50 | 10.20 to 10.30 |
C | 9.50 to 10.00 | 10.30 to 10.40 |
D | 10.00 to 10.10 | 10.40 to 10.50 |
E | 10.10 to 10.20 | 9.30 to 9.40 |
F | 10.20 to 10.30 | 9.40 to 9.50 |
G | 10.30 to 10.40 | 9.50 to 10.00 |
H | 10.40 to 10.50 | 10.00 to 10.10 |
Due to requests from the candidates, the interview schedule was altered for several candidates. The alterations were made in such a way that whenever a change was made, the time schedule for both the panels of a particular candidate was exchanged in entirety with the time schedule of another candidate. The following alterations were made:
I. A's place was taken by G
II. A in turn was accommodated in C's place
III. C in turn was accommodated in E's place
IV. E took H's place
V. H took G's place
