Direction: There are eight persons M, N, O, P, Q, R, S and T are living on separate floors of an 8- floor building. The ground floor is numbered 0, the first floor is numbered 1 and so on until the topmost floor is numbered 7. Each one of them lives in a different number of flat i.e. 56, 63, 67, 73, 88, 92, 103 and 107 but not necessarily in the same order. G.F. is neither an even nor an odd-numbered floor.

The person who lives in flat number 67 lives immediately below N’s floor.
The difference in the floors between T and N is the same as the difference in the floors between N and O.

• O lives neither on floor number 3 nor 1. 
• The highest numbered floor is at the lowermost floor. 
• P lives on an odd-numbered floor and immediately above the one who lives in flat number 88. 
• M lives on an odd-numbered floor and there are two floors between M’s floor and the one who lives in flat number 103. 
• T lives on an even-numbered floor. 
• N lives in that flat which a number is a prime number. 
• The difference in the flat number of P and the one who lives in floor number 1 is 11. 
• N lives three floors below S’s floor who lives on an even-numbered floor. 
• The difference in the flat number of M and N is 40. 
• The flat number of Q is a prime number. 
• Q lives immediately above that person who lives in flat number 103.
