Which set of skills is typically tested under Numerical/Quantitative Reasoning on the NJ civil service exam?

• A. Algebra and calculus problems only.
• B. Geometry, trigonometry, and statistics.
• C. Word problems that require only reasoning, not numbers.
• D. Fractions, decimals, percentages, ratio problems, basic algebra, and word problems requiring calculation.

Answer: (D)

Numerical/Quantitative Reasoning centers on using numbers to solve practical problems you’d encounter on the job. The strongest fit includes fractions, decimals, percentages, and ratio problems, along with basic algebra, and it also covers word problems that require calculation. This mix reflects what you actually do when interpreting data, performing straightforward calculations, and turning written scenarios into solvable math steps on the NJ civil service exam. The other descriptions miss essential elements: one focuses only on algebra or even calculus, which isn’t the typical scope and omits the arithmetic basics; another emphasizes geometry, trigonometry, and statistics instead of the everyday number sense used in civil service problems; and another suggests word problems that require only reasoning without numbers, which contradicts the numerical focus of this section. To study effectively, practice a variety of numeric word problems, work on converting between fractions, decimals, and percentages, and set up and solve simple algebraic statements from word problems.
