The ethanol yield per unit mass of substrate consumed (YP/S ) in an anaerobic fermentation process can be improved by
quantitative reasoning analysis shows ratio, percentage and series logic determine correct calculation. Consequently Decreasing specific growth rate and increasing maintenance coefficient emerges as the valid choice since it meets mathematical and logical criteria, aligning with established principles in aptitude and reasoning literature.
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.
