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

Six individuals – P, Q, R, S, T, and U – scheduled their vacation trips in three different months – March, June, and November – on two distinct dates, namely 11th and 18th of the same year. Each individual visits a different city – Boston, Dallas, Miami, Seattle, Chicago, and Denver. All the given information is not necessarily applied in the same order.

The one who visits Boston was scheduled two persons before R. Q was scheduled immediately before R on an even date. T was scheduled immediately before U on an odd date in a month having 30 days. Two persons were scheduled between U and the person visiting Miami. Two persons were scheduled between the ones visiting Boston and Chicago. P was scheduled before the one who visits Denver and two persons after the one who visits Seattle. U doesn’t visit Seattle.

How many persons were scheduled between R and the one who visits Chicago?

The correct answer is None.

Step-by-Step Explanation:

1. Understand the Schedule Structure:
There are 6 total slots across 3 months on two specific dates (11th and 18th):
• Slot 1: March 11 (31 days, Odd date)
• Slot 2: March 18 (31 days, Even date)
• Slot 3: June 11 (30 days, Odd date)
• Slot 4: June 18 (30 days, Even date)
• Slot 5: November 11 (30 days, Odd date)
• Slot 6: November 18 (30 days, Even date)

2. Determine the positions of Q, R, and Boston:
• "Q was scheduled immediately before R on an even date."
• "The one who visits Boston was scheduled two persons before R."
If Q is on March 18 (Slot 2, even date), then R is on June 11 (Slot 3).
Two persons before R means Boston is scheduled on March 11 (Slot 1).
So, Slot 1 = Boston, Slot 2 = Q, Slot 3 = R.

3. Determine the positions of T and U:
• "T was scheduled immediately before U on an odd date in a month having 30 days."
Months with 30 days are June and November. Odd dates in these months are June 11 (Slot 3) and November 11 (Slot 5).
Since Slot 3 is already occupied by R, T must be scheduled on November 11 (Slot 5).
U is immediately after T, so U is scheduled on November 18 (Slot 6).

4. Determine the positions of Chicago, Seattle, and P:
• "Two persons were scheduled between the ones visiting Boston and Chicago."
Boston is at Slot 1 (March 11). Counting two persons between (Slot 2 and Slot 3), Chicago must be at Slot 4 (June 18).
• "P was scheduled before the one who visits Denver and two persons after the one who visits Seattle."
The available person slots left are Slot 1 and Slot 4. Since P is two persons after Seattle, P must be at Slot 4 (June 18), which means the person at Slot 2 (Q) visits Seattle.
The remaining individual S takes Slot 1 (March 11).

5. Determine the position of Miami:
• "Two persons were scheduled between U and the person visiting Miami."
U is at Slot 6 (November 18). Counting two persons between (Slot 5 and Slot 4), Miami must be at Slot 3 (June 11, R).

Final Arrangement:
• Slot 1 (March 11): S – Boston
• Slot 2 (March 18): Q – Seattle
• Slot 3 (June 11): R – Miami
• Slot 4 (June 18): P – Chicago
• Slot 5 (November 11): T – Dallas / Denver
• Slot 6 (November 18): U – Denver / Dallas

Conclusion:
R is scheduled at Slot 3 (June 11) and the person visiting Chicago (P) is scheduled at Slot 4 (June 18).
Since Slot 3 and Slot 4 are consecutive, there are 0 (None) persons scheduled between R and the person visiting Chicago.
