Study the following information carefully and answer the questions given below:

Eight persons – P, Q, R, S, T, U, V, and W were born in different months – January, February, April, May, July, August, October, and November of the same year, but not necessarily in the same order. Q was born in a month which has 30 days, but not in November. Four persons were born between Q and V. Two persons were born between V and T. P was born in the month of January. R was born in the month which has fewer than 30 days. S was born in the month immediately preceding July. W was born in the month immediately preceding U.

Study the following information carefully and answer the questions given below:

How many persons were born between R and T?

The correct option is Two.

Step-by-Step Explanation and Logic:

Let us arrange the given months in chronological order with the number of days in each month:

1. January (31 days)
2. February (28/29 days - fewer than 30 days)
3. April (30 days)
4. May (31 days)
5. July (31 days)
6. August (31 days)
7. October (31 days)
8. November (30 days)

Now, let us use the given clues step-by-step to place each person:

1. P was born in January:
January = P

2. R was born in the month which has fewer than 30 days:
The only month with fewer than 30 days is February.
February = R

3. S was born in the month immediately preceding July:
The month immediately preceding July is May.
May = S

4. Q was born in a month which has 30 days, but not in November:
The months with 30 days are April and November. Since Q was not born in November, Q must be born in April.
April = Q

5. Four persons were born between Q and V:
Q is in April (2nd position after Jan, Feb). Counting four persons after April (May, July, August, October), V must be born in November.
November = V

6. Two persons were born between V and T:
V is in November. Counting two months backwards from November (October, August), T must be born in July.
July = T

7. W was born in the month immediately preceding U:
The remaining available months are August and October.
Therefore, W was born in August, and U was born in October.
August = W
October = U

Final Arrangement:

• January: P
• February: R
• April: Q
• May: S
• July: T
• August: W
• October: U
• November: V

Answering the Question:

The question asks: "How many persons were born between R and T?"

• R was born in February.
• T was born in July.

The persons born between February and July are Q (April) and S (May).
Therefore, exactly Two persons (Q and S) were born between R and T.
