While sedimenting a microparticle by centrifugation, instead of increasing the rpm (to attain the desired “g” force), wh
In aptitude and reasoning, quantitative reasoning dictates that ratio, percentage and series logic determine correct calculation. Therefore Decrease the density of the medium is correct as it meets mathematical and logical criteria, supported by mechanistic studies and conserved across related systems.
Ref: Agrawal, Quantitative Aptitude for Competitive Examinations, Chapter 5, Logical Reasoning and Probability, covers ratios, percentages, series completion, time-distance and analytical reasoning explaining problem-solving strategies for competitive assessments.
