Detailed Solution
Download Solution PDFGiven: Each of C, D, E, F, S, T and U has an exam on a different day of a week, starting from Monday and ending on Sunday of the same week.
There are 7 days in a week and 7 people, so each person has an exam on one day.
1) F has the exam on Friday.
| Day | Person |
| Monday | |
| Tuesday | |
| Wednesday | |
| Thursday | |
| Friday | F |
| Saturday | |
| Sunday |
2) Only two people have their exams between T and F. T should be before F.
| Day | Person |
| Monday | |
| Tuesday | T |
| Wednesday | |
| Thursday | |
| Friday | F |
| Saturday | |
| Sunday |
3) Only four people have their exams between E and T.
| Day | Person |
| Monday | |
| Tuesday | T |
| Wednesday | |
| Thursday | |
| Friday | F |
| Saturday | |
| Sunday | E |
4) S has the exam immediately after U.
If S is immediately after U, then U and S must occupy two consecutive empty slots.
So U is on Wednesday and S is on Thursday.
| Day | Person |
| Monday | |
| Tuesday | T |
| Wednesday | U |
| Thursday | S |
| Friday | F |
| Saturday | |
| Sunday | E |
5) D does not have the exam on Monday.
Since D does not have the exam on Monday, D must have the exam on Saturday.
This leaves Monday for C.
| Day | Person |
| Monday | C |
| Tuesday | T |
| Wednesday | U |
| Thursday | S |
| Friday | F |
| Saturday | D |
| Sunday | E |
Four people have their exams before D and after C.
Hence, the correct answer is "Option 2".
