When the test-makers are creating questions for the LSAT, they have a vast array of “weapons” with which to attack. They can create sophisticated stimuli, complicated questions, and cleverly appealing incorrect answer choices. A more specific example is their use of numbers and percentages; as discussed in our PowerScore Logical Reasoning Bible, the test-makers prey upon several common misunderstandings about what can be gleaned from limited data.
Many people find it somewhat counter-intuitive that a company with a sharply declining market share could at the same time be seeing profits on the rise. But, as discussed in the LRB, a rising percentage isn’t necessarily associated with increasing numbers, and a decreasing percentage is not always associated with a decrease in the bottom line figure (for more on numbers, percentages, and the many other ways that Logical Reasoning questions are constructed to be difficult, see the discussion in the Logical Reasoning Bible Chapter 17.
