PSAT Math Multiple-Choice Question 530: Answer and Explanation

Question: 530

A company conducted a survey in which it asked 500 of its employees whether they were satisfied with their current work schedule. The table below shows the responses from all 500 employees that completed the survey.

	Part-time	Full-time
Satisfied with schedule	126	119
Dissatisfied with schedule	108	?

How many of the full-time employees reported that they were dissatisfied with their work schedules?

• A. 147
• B. 174
• C. 246
• D. 354

Correct Answer: A

Explanation:

A

The question asks for the number of full-time employees that were dissatisfied with their work schedules. Looking at the chart, the space under the column "Full-time" in the row "Dissatisfied" is the only box that is not filled in. Call this number x. Read the information above the chart to determine how many employees were surveyed. The question states that 500 employees were surveyed, so the numbers in the chart add up to 500, or 126 + 119 + 108 + x = 500. Simplify to 353 + x = 500, then subtract 353 from both sides to get x = 147. The correct answer is (A).
