Read the following information carefully and mark the correct answer to the questions given below
Sampada Apartment is a housing society formed by a group of professors of a University. It has six flats on a floor in two rows facing North and South which are allotted to Prof. Purohit, Prof. Qureshi, Prof. Rathor, Prof. Sawant, Prof. Tripathy and Prof. Usman. Prof. Qureshi gets a North facing flat and it is not next to Prof. Sawant’s flat. Prof. Sawant and Prof. Usman get their flats which are diagonally opposite to each other. Prof. Rathor gets a south facing flat which is next to Prof. Usman’s flat. Prof. Tripathy’s flat is North facing.
If the flats of Prof. Tripathy and Prof. Purohit are interchanged, whose flat will be next to that of Prof. Usman?
We are given that,
Prof. Rathor gets a south facing flat which is next to Prof. Usman’s flat
Thus, Rathor's and Usman's flat are facing South.
Prof. Sawant and Prof. Usman get their flats which are diagonally opposite to each other
Thus, Sawant's flat is North facing and his flat and Usman's flat are at the opposite ends.
Prof. Rathor gets a south facing flat which is next to Prof. Usman’s flat
Thus, Rathod's flat is facing South.
Thus, Purohit's flat is facing North and so is Tripathy's
The condition is as shown below:-
Thus, If the flats of Prof. Tripathy and Prof. Purohit are interchanged, Prof. Rathor flat will be next to that of Prof. Usman.
Hence, option A is the correct answer.
