CA Foundation · Quantitative Aptitude · Seating Arrangements
In a seating puzzle with eight persons in a row, a student finds that a clue leads to two possible arrangements, and a later clue contradicts one of them. What should the student do?
The student should discard the arrangement that a later clue contradicts and continue with the surviving one. Every valid arrangement must satisfy all clues, so a case violating any clue is eliminated, and the consistent case gives the answer.
- ADiscard the contradicted arrangement and continue with the one that remains consistent with all cluesCorrect
- BKeep both arrangements and choose the one that looks neater
- CRestart with a different anchor person
- DAssume the later clue is misprinted
Explanation
A valid arrangement must satisfy every clue. When one case violates a clue, it is eliminated. The surviving case is the only one consistent with all the information, so work continues with it. Keeping an arrangement that violates a clue gives wrong answers.
