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?

Correct Answer: V

Step-by-step Explanation:

Let's analyze the given information step-by-step to determine the birth month of each person.

1. List of Months and Number of Days:

1. January (31 days)
2. February (28/29 days)
3. March (31 days)
4. April (30 days)
5. May (31 days)
6. June (30 days)
7. July (31 days)
8. August (31 days)

2. Analyzing the Clues:

- "P was born three months before V."
This means the month gap between P and V is 3 months (i.e., Month of V - Month of P = 3).
Possible pairs for (P, V):
• If P is in January (1st month) ⇒ V is in April (4th month)
• If P is in February (2nd month) ⇒ V is in May (5th month)
• If P is in March (3rd month) ⇒ V is in June (6th month)
• If P is in April (4th month) ⇒ V is in July (7th month)
• If P is in May (5th month) ⇒ V is in August (8th month)

- "Four persons were born between R and W who was born just after S."
W is born immediately after S (S and W are consecutive: S then W).
There are 4 months/persons between R and W.

- "R and T were born in the adjacent month having 31 days."
Adjacent months that both have 31 days are July and August. So, R and T must be born in July and August (in some order).

Case 1: R is born in August (8th month)
If R is in August (8th month), since 4 persons are born between R and W:
W must be born in March (3rd month).
Since W is born just after S, S must be born in February (2nd month).
Then T must be born in July (7th month), as R (August) and T (July) are in adjacent 31-day months.
Now we need to place (P, V) such that P is 3 months before V.
The available empty months are: January (1st), April (4th), May (5th), June (6th).
If P is in January (1st), V is in April (4th). This fits perfectly!
Now the remaining person U must be placed in the remaining empty month, which would be May or June.
However, the clue states: "U was neither born in May nor in June." Thus, Case 1 fails.

Case 2: R is born in July (7th month)
If R is in July (7th month), since 4 persons are born between R and W:
W must be born in February (2nd month).
Since W is born just after S, S must be born in January (1st month).
Then T must be born in August (8th month), as R (July) and T (August) are in adjacent 31-day months.
Now we need to place (P, V) such that P is 3 months before V.
The remaining available months are: March (3rd), April (4th), May (5th), June (6th).
If P is in March (3rd month) ⇒ V is in June (6th month).
Now, the available months for U and Q are April (4th) and May (5th).
Since "U was neither born in May nor in June", U must be born in April (4th month).
Therefore, Q must be born in May (5th month).

Final Arrangement:

• 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)

3. Finding the Odd One Out:

Let's check the number of days in the month each person was born in:

• R was born in July, which has 31 days.
• S was born in January, which has 31 days.
• P was born in March, which has 31 days.
• T was born in August, which has 31 days.
• V was born in June, which has 30 days.

All persons except V were born in a month having 31 days. V was born in June, a month having 30 days. Hence, V doesn't belong to the group.
