Why this answer is correct
Given: Eight persons, namely, P, Q, R, S, T, U, V, and W, attend a workshop in different months: September, October, November, and December, on two different dates: 11 and 22, but not necessarily in the same order.
- W attends the workshop on the 11th of a month having 30 days.
| Months | Dates | Persons | |
|---|---|---|---|
| Case 1 | Case 2 | ||
| September (30) | 11 | W | |
| 22 | |||
| October (31) | 11 | ||
| 22 | |||
| November (30) | 11 | W | |
| 22 | |||
| December (31) | 11 | ||
| 22 |
- Three persons attend between W and R.
| Months | Dates | Persons | |
|---|---|---|---|
| Case 1 | Case 2 | ||
| September (30) | 11 | W | R |
| 22 | |||
| October (31) | 11 | ||
| 22 | |||
| November (30) | 11 | R | W |
| 22 | |||
| December (31) | 11 | ||
| 22 |
- T attends the workshop on an even date before R and after W.
Now, we can eliminate Case 2, but we have a subcase of Case 1, i.e., Case 1a.
| Months | Dates | Persons | |
|---|---|---|---|
| Case 1 | Case 1a | ||
| September (30) | 11 | W | W |
| 22 | T | ||
| October (31) | 11 | ||
| 22 | T | ||
| November (30) | 11 | R | R |
| 22 | |||
| December (31) | 11 | ||
| 22 |
- S attends immediately before R.
Now, we can eliminate Case 1a.
| Months | Dates | Persons |
|---|---|---|
| Case 1 | ||
| September (30) | 11 | W |
| 22 | T | |
| October (31) | 11 | |
| 22 | S | |
| November (30) | 11 | R |
| 22 | ||
| December (31) | 11 | |
| 22 |
- Three people attend between T and U, where T attended before U.
| Months | Dates | Persons |
|---|---|---|
| Case 1 | ||
| September (30) | 11 | W |
| 22 | T | |
| October (31) | 11 | |
| 22 | S | |
| November (30) | 11 | R |
| 22 | U | |
| December (31) | 11 | |
| 22 |
- Q attends the workshop in a month having 31 days, but not on an odd-numbered date.
| Months | Dates | Persons |
|---|---|---|
| Case 1 | ||
| September (30) | 11 | W |
| 22 | T | |
| October (31) | 11 | |
| 22 | S | |
| November (30) | 11 | R |
| 22 | U | |
| December (31) | 11 | |
| 22 | Q |
- V attends after P.
This is our final arrangement,
| Months | Dates | Persons |
|---|---|---|
| Case 1 | ||
| September (30) | 11 | W |
| 22 | T | |
| October (31) | 11 | P |
| 22 | S | |
| November (30) | 11 | R |
| 22 | U | |
| December (31) | 11 | V |
| 22 | Q |
Hence, the correct answer is U.
