The correct answer with a full explanation. Practice Puzzles & Arrangements questions as a quiz →
एका रांगेमध्ये 'A' डाव्या बाजूने 11 व्या स्थानावर आहे आणि 'B' उजव्या बाजूने 10 व्या स्थानावर आहे. जर 'A' आणि 'B' यांच्या जागांची अदलाबदल केली तर 'A' डाव्या बाजूने 18 व्या स्थानावर येतो. तर या रांगेमध्ये 'A' आणि 'B' खेरीज किती व्यक्ती असतील?
After interchanging, A's new position from the left is 18th. Since B was originally 10th from the right, total persons in the row = (A's new position from left) + (B's original position from right) - 1 = 18 + 10 - 1 = 27. Persons between A and B (excluding A and B) = Total - 2 = 27 - 2 = 25.
