Directions (91-95) : Study the following information carefully and answer the questions given below:

Eight persons P, Q, R, S, T, U, V and W (but not necessarily in the same order) were born on the 21st of eight different months i.e., January,February, March, April, May, June, July and August of the same year. Four persons were born between R and W who was born just after S. R and T were born in the adjacent month having 31 days. P was born three months before V. U was neither born in May nor in June.

Four of the following five are alike in a certain way and thus form a group, then who among the following doesn’t belong to that group?

The correct option is V.

Step-by-step Explanation:

Let's analyze the given information step-by-step to determine the birth months of all eight persons (P, Q, R, S, T, U, V, W):

1. Months and Number of Days:
- January: 31 days
- February: 28/29 days
- March: 31 days
- April: 30 days
- May: 31 days
- June: 30 days
- July: 31 days
- August: 31 days

2. Clues breakdown:
- "W was born just after S." This means S and W are born in consecutive months (S immediately followed by W).
- "Four persons were born between R and W."
- "R and T were born in adjacent months having 31 days." The consecutive months with 31 days in our list are July and August. Thus, R and T must be born in July and August (in some order).
- If R is born in August (31 days):
Counting back 4 months between R and W: July, June, May, April. Thus W would be born in March.
Since W was born just after S, S must be born in February.
Now let's check T: T must be in July (adjacent month to R with 31 days).
- "P was born three months before V." This means there is a gap of 2 months between P and V (e.g., if V is in month m, P is in month m - 3).
Looking at available months: January, April, May, June.
If V is in June, P would be born 3 months before June, which is March (already occupied by W).
If V is in May, P is in February (occupied by S).
If V is in April, P is in January (available!).
So, P is born in January and V is born in April.
- Now, the remaining months are May and June, and the remaining persons are U and Q.
- "U was neither born in May nor in June." Wait, let's re-verify the placement of U and Q.
If R is born in July instead of August:
Counting back 4 months between R and W: June, May, April, March. Thus W is born in February.
If W is in February, S is born in January.
R is in July, so T must be in August (adjacent 31-day month).
Remaining months for P, V, U, Q: March, April, May, June.
"P was born three months before V":
- If V is in June, P is in March (3 months before June).
- If V is in May, P is in February (occupied).
So, P is in March and V is in June.
Remaining months are April and May for U and Q.
"U was neither born in May nor in June."
Since U cannot be in May, U must be born in April.
Then Q must be born in May.

3. Final Schedule:
- January: S (31 days)
- February: W (28/29 days)
- March: P (31 days)
- April: U (30 days)
- May: Q (31 days)
- June: V (30 days)
- July: R (31 days)
- August: T (31 days)

4. Analyzing the Options to Find the Odd One Out:
- R was born in July (a month with 31 days).
- S was born in January (a month with 31 days).
- P was born in March (a month with 31 days).
- V was born in June (a month with 30 days).

All persons except V were born in months having 31 days. Therefore, V does not belong to the group.
