How many persons are living below the one who likes RED?

The one who likes Pink lives on an odd number of floors and lives three floors below U, whose age is 32 years. P, whose age is 27 years, lives just below the one who likes Pink. That means, P lives on the floor marked 2. At most two floors are there between a person just above U’s floor and the one whose age is 21 years. That means, in case (1) the one whose age is 21 years live on the floor marked 5, in case (2) the one whose age is 21 year lives on the floor marked 4. Based on the above given information we have:  The age of R is 3/4th of the ages of the one who likes Yellow. Since, only such possible combination is (28, 21).  A person living just above R lives two floors away from the one who likes Yellow. That means, in case (1) the one who likes Yellow lives on the floor marked 4, in case (2) the one who likes Yellow lives on the floor marked 7.  Two persons are living between the one who likes Blue and T, who likes White. The number of persons living below T is one less than the number of persons living above the one who likes Black. Sum of ages of T and the one who likes Pink is twice the ages of Q. Ages of Q is neither an odd number nor likes Yellow. Since, the only possible combination is (23, 29, 26). That means, in case (2b) T lives on the floor marked 1, case (1) & case (2a) are not valid. Based on the above given information we have: Case (1) & case (2a) are not valid as two persons are living between the one who likes Blue and T, who likes White. Again, we have: At least two persons are living between S and the one who likes RED. The one who likes RED lives just above the one whose age is 29 years. That means, S lives on the floor marked 7, and the age of T is 29 years. Based on the above given information we have the final arrangement as follows:
