Problem Solving Questions

Both Problem-Solving and Data-Sufficiency questions require knowledge of arithmetic, elementary algebra and commonly known concepts of geometry.

Problem-Solving questions are designed to test basic mathematical skills, understanding of elementary mathematical concepts and the ability to reason quantitatively and solve quantitative problems.

Sample Question
Directions
Solve the problem and indicate the best of the answer choices given.

Numbers
All numbers used are real numbers.

Figures
A figure accompanying a problem solving question is intended to provide information useful in solving the problem. Figures are drawn as accurately as possible EXCEPT when it is stated in a specific problem that the figure is not drawn to scale. Straight lines may sometimes appear jagged. All figures lie in a plane unless otherwise indicated.

I. u > s
II. s > q
III. u > r

(A) I only
(B) II only
