Two solutions of a substance (non-electrolyte) are mixed in the following manner: 480 ml of 1.5 M first solution + 520 m
This outcome reflects quantitative reasoning, where ratio, percentage and series logic determine correct calculation. Option B captures this correctly because it meets mathematical and logical criteria, consistent with textbook descriptions and experimental observations in aptitude and reasoning.
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.
