Detailed Solution
Download Solution PDFGiven: E, F, G, I, K, L and M each have their exams on different days of the week starting from Monday and ending on Sunday of the same week.
1) Only three people have exams between M and K.
2) K has his exam on the last day of the week.
| Weekdays | Person |
| Monday | |
| Tuesday | |
| Wednesday | M |
| Thursday | |
| Friday | |
| Saturday | |
| Sunday | K |
3) Only one person has an exam between I and E.
4) E has his exam on any day before I.
| Weekdays | Person | |
| Case 1 | Case 2 | |
| Monday | ||
| Tuesday | E | |
| Wednesday | M | M |
| Thursday | E | I |
| Friday | ||
| Saturday | I | |
| Sunday | K | K |
5) L has his exam exactly one day before F.
6) G does not have an exam on Friday.
As there is no possible position for G in case 1, therefore is eliminated.
| Weekdays | Person |
| Case 2 | |
| Monday | G |
| Tuesday | E |
| Wednesday | M |
| Thursday | I |
| Friday | L |
| Saturday | F |
| Sunday | K |
Thus, according to the final arrangement six people have exams after G.
Hence, "Option 4" is the correct answer.
