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

Six executives—P, Q, R, S, T, and U—occupy individual floors of a six-storey office building, numbered 1 (ground floor) through 6 (topmost floor). Each executive decorates their workspace with a different theme: Minimalist, Vintage, Rustic, Modern, Industrial, and Bohemian.

T resides on an odd-numbered floor above floor 1, but does not use the Minimalist or Bohemian themes. Exactly two people live between T and the person whose office is decorated in a Vintage style. The person with the Modern office lives on a floor immediately above the one with the Vintage office. Q lives on a floor higher than the person with the Modern office, but Q's office is not Rustic. The number of floors below S is equal to the number of floors above R. P lives on an even-numbered floor below R. The executive with the Bohemian theme lives on a floor above the one with the Industrial theme, but below U. S does not have a Rustic or Minimalist theme.

The number of persons lives above S is one less than the number of persons live below ____.

The correct answer is U.

Step-by-step Explanation:

1. Understanding the Building Layout:
There are 6 floors numbered 1 (ground floor) to 6 (topmost floor). Six executives—P, Q, R, S, T, and U—occupy one floor each.

2. Analyzing the Clues for Floor Positions:

• The number of floors below S is equal to the number of floors above R:

$\text{Floors below S}=\text{Floors above R}$

$(\text{Floor of S}-1)=(6-\text{Floor of R})$

$\text{Floor of S}+\text{Floor of R}=7$

• T lives on an odd-numbered floor above floor 1, so T can reside on floor 3 or floor 5.
• Evaluating the floor conditions places S on floor 2 and R on floor 5 (since 2 + 5 = 7).
• U lives on the topmost floor, floor 6.

3. Calculating the Question Requirement:

• Since S resides on floor 2, the number of persons living above S (on floors 3, 4, 5, and 6) is:

$6-2=4$

• The question asks for the person below whom the number of residents is 1 more than the number of persons living above S:

$\text{Persons below target}-1=4\Rightarrow \text{Persons below target}=5$

• The executive with exactly 5 persons living below them (floors 1, 2, 3, 4, and 5) is the one living on floor 6, which is U.

Therefore, the number of persons living above S (4) is one less than the number of persons living below U (5).
