Step 1: Understand the question
We are asked: Who should occupy the office furthest from Mr. Brar? To answer this, we must carefully analyze the conditions given in the passage, especially the restrictions involving adjacency, smoking habits, silence requirements, and Miss Harsha’s fixed office number.
Step 2: Fix the immovable condition
Miss Harsha, being a senior employee, must be allotted office number 5. Also, since she is allergic to tobacco smoke, offices 4 and 6 must be occupied by non-smokers.
Step 3: Place smokers logically
The smokers are Mr. Tanjore, Mr. Minhas, and Mr. Dongre. They cannot be placed in offices 4 or 6 because those must be non-smokers (due to Harsha’s allergy). This means the smokers must be fitted into offices 1, 2, and 3. This automatically pushes non-smokers like Ruby and Brar into offices 4 and 6. (Harsha is already in 5).
Step 4: Adjacency of Brar and Minhas
Brar and Minhas must be in adjacent offices. Since Brar is a non-smoker, he can only be in office 4 or 6. If Brar is in 4, Minhas could only be in 3 (which is a smoker’s position). If Brar is in 6, Minhas could only be in 5, but 5 is already taken by Harsha. So the only workable placement is Brar in 4 and Minhas in 3.
Step 5: Silence condition for Dongre
Dongre requires silence in the adjacent offices. If Dongre is placed on the extreme end, i.e., office 1, then only office 2 needs to be silent. This is easier to manage because Ruby, who uses the telephone frequently, should not be next to him. Ruby can be placed in office 6 instead, far away from Dongre.
Step 6: Identify the "furthest" office from Brar
Since Brar is in office 4, the furthest office in the row is office 1 (because offices are numbered in a line from 1 to 6). And the best candidate for office 1, as we reasoned, is Mr. Dongre. His need for silence is respected since Ruby is placed at the opposite end in office 6, and smokers like Tanjore can be positioned near him without conflict.
Step 7: Conclusion
Therefore, the ideal candidate to occupy the office furthest from Mr. Brar is Mr. Dongre.
Final Answer: The correct option is (D): Mr. Dongre
