Quizplus · Accepted Answer

Fluid intelligence involves the capacity to think logically and solve problems in novel situations, independent of acquired knowledge. It typically declines with age, whereas crystallized intelligence, which involves knowledge that comes from prior learning and past experiences, tends to increase or remain stable with age. Calculating a discount quickly is more about problem-solving and mental agility, aspects of fluid intelligence.
