खालील संख्यांमधून विसंगत संख्या शोधा : 343, 324, 3375, 10648, 64

Option C matches the question because 343=7³, 3375=15³, 10648=22³, and 64=4³ are perfect cubes; 324=18² is a perfect square but not a cube—the odd man out. Picking any cube misidentifies the non-cube interloper in the set. You can eliminate A (64), B (3375), D (10648) — each one conflicts with the principle or calculation that leads to option C. Keep the name, formula, and unit together in your notes — that helps you spot incomplete distractors quickly.
