Question
Who lives immediately above Q in the same flat
number? Answer the questions based on the information given below. Eleven persons A, B, C, D, P, Q, R, S, X, Y and Z live in four storey building having four floors such that lowermost floor is numbered as 1 and floor immediately above the lowermost floor is numbered as 2 and so on. Each floor has 3 flats numbered as 1, 2 and 3 from west to east such that flat тАУ 1 is in west of flat тАУ 2 and flat тАУ 2 is in west of flat тАУ 3. One of the flats on a floor is vacant. The dimensions of each of the flats are same. Note: If there is one/two floor(s) between two flats then they may or may not have the same flat number of different floors. Z lives in an even numbered flat on floor number 2. B and C live on same floor. B lives in an even numbered flat on lowermost floor. R and A live on same floor. All the flats on the floor on which Q lives are occupied. X lives to the west of R. B lives on the floor on which two other persons live. There is one floor between R and Q. PтАЩs flat is immediately above CтАЩs flat and the numbers of their flats is same. R lives immediately below the vacant flat and the flat number of vacant flat and R is same. D lives somewhere above Y in same flat number, but not on flat 3.A lives in flat тАУ 1.Solution
B lives in an even numbered flat on lowermost floor i.e. B lives on floor ground floor in flat 2. Z lives in an even numbered flat on floor number 2. B and C live on same floor. P lives immediately above C and the numbers of their flats is same. So, Now, C either lives immediate west or east of B which means P either lives in flat 3 or flat 1. So, we have two possibilities. Case I: When C and P live on flat тАУ 3:
Case-2 When C and P live on Flat-1
R and A live on same floor. X lives to the immediate west of R. R lives immediately below the vacant flat and the flat number of vacant flat and R is same. A lives in flat тАУ1. There is one floor between R and Q. Now, R lives immediately below vacant flat so, the vacant flat must be in topmost floor. Case I: When C and P live on flat тАУ 3:
Case II: When C and P live on flat тАУ 1
D lives somewhere above Y in same flat number, but not on flat 3. Now, we cannot fix D and Y in same flat number in case II, so, case II is invalid. The final arrangement is as follows:
