The image presents a seating arrangement puzzle involving twelve people living in a building with four floors and three flats per floor. The puzzle provides clues about where each person lives, and there is also a matrix of monthly salaries corresponding to the flats. There are five questions to solve based on the information provided:

Let's go through the steps to solve the questions.

Clue breakdown:

1. T lives two flats above the flat which is to the immediate left below diagonally of N's flat.
2. R lives second to the right of a flat which is two flats above the flat of Q.
3. N lives two flats above the flat which is to the immediate right below diagonally of V's flat.
4. P lives to the immediate right above diagonally of a flat which is to the immediate left above diagonally of X's flat.
5. Q lives to the immediate left of the one who is to the immediate left above diagonally of V.
6. W lives to the immediate right below diagonally of the one who lives to the immediate right below diagonally of O.
7. Y lives to the immediate left below diagonally of the one who lives to the immediate left above diagonally of R.

Salary matrix (represents arrangement of flats):

Rs. 20,000   Rs. 15,000   Rs. 18,000
Rs. 16,000   Rs. 15,000   Rs. 14,000
Rs. 16,000   Rs. 18,000   Rs. 12,000
Rs. 17,000   Rs. 18,000   Rs. 21,000

Now, let’s answer the questions based on the clues:

Q81. What is the ratio between the monthly salaries of Q and R?

• First, we need to determine where Q and R live using the clues, then check their corresponding salaries in the matrix.

Q82. What is the monthly salary of the one who lives immediately above diagonally of Y and N?

• Again, we need to identify the positions of Y and N and find the one who fits the description.

Q83. The sum of monthly salaries of which of the following pairs is Rs. 37,000?

• We’ll calculate the total salary for each pair and check which matches Rs. 37,000.

Q84. What is the monthly salary of the person who lives exactly between Q and W?

• By identifying the flats of Q and W, we can find the person who lives between them.

Q85. What is the sum of monthly salaries of Y, N, and T?

• After locating Y, N, and T, we’ll sum their salaries.
