LASD Mathematics and Numerical Reasoning 2 — Questions and Answers
Question 1: Over 5 days, a station received 32, 45, 28, 51, and 44 calls. What was the average number of daily calls?
- 38
- 40 (Correct answer)
- 42
- 44
Correct answer: 40
(32 + 45 + 28 + 51 + 44) ÷ 5 = 200 ÷ 5 = 40 calls per day.
Question 2: The ratio of sworn deputies to civilian staff at a station is 3:1. If there are 24 civilian staff members, how many sworn deputies are there?
- 60
- 66
- 72 (Correct answer)
- 78
Correct answer: 72
With a 3:1 ratio and 24 civilian staff, sworn deputies = 3 × 24 = 72.
Question 3: A suspect fled on foot and was captured after traveling 1.2 miles in 12 minutes. What was the suspect's average speed in miles per hour?
- 4 mph
- 5 mph
- 6 mph (Correct answer)
- 7 mph
Correct answer: 6 mph
1.2 miles ÷ (12/60) hours = 1.2 ÷ 0.2 = 6 mph.
Question 4: A department budget was $2,400,000 last year and increased by 15% this year. What is this year's budget?
- $2,640,000
- $2,700,000
- $2,760,000 (Correct answer)
- $2,800,000
Correct answer: $2,760,000
$2,400,000 × 1.15 = $2,760,000 for this year's budget.
Question 5: A deputy's shift starts at 10:45 PM and lasts 8 hours and 30 minutes. What time does the shift end?
- 6:45 AM
- 7:00 AM
- 7:15 AM (Correct answer)
- 7:30 AM
Correct answer: 7:15 AM
10:45 PM + 8 hours = 6:45 AM; 6:45 AM + 30 minutes = 7:15 AM.
Question 6: If 3 deputies can process 18 reports in 2 hours, how many reports can 5 deputies process in the same 2-hour period?
- 25
- 28
- 30 (Correct answer)
- 32
Correct answer: 30
Each deputy processes 6 reports in 2 hours; 5 × 6 = 30 reports total.
Question 7: A vehicle pursuit covers 12 miles at an average speed of 80 mph. Approximately how many minutes does the pursuit last?
- 7 minutes
- 9 minutes (Correct answer)
- 11 minutes
- 13 minutes
Correct answer: 9 minutes
Time = 12 ÷ 80 = 0.15 hours; 0.15 × 60 = 9 minutes.
