  1. Out of 200 applicants to the LASD, 45% passed the written exam. How many applicants passed?

    Answer: 90

    45% × 200 = 0.45 × 200 = 90 applicants passed the written exam.

  2. A rectangular holding area measures 30 feet by 18 feet. What is the area of the room in square feet?

    Answer: 540 sq ft

    Area = length × width = 30 × 18 = 540 square feet.

  3. A deputy drove 130 miles on Monday and 260 miles on Tuesday. If the patrol vehicle gets 26 miles per gallon, how many gallons of fuel were used over the two days?

    Answer: 15 gallons

    Total miles = 130 + 260 = 390; 390 ÷ 26 = 15 gallons of fuel.

  4. An LASD trainee scored 72, 85, 91, and 78 on four consecutive practice exams. What is the trainee's average score?

    Answer: 81.5

    (72 + 85 + 91 + 78) ÷ 4 = 326 ÷ 4 = 81.5.

  5. A parking enforcement officer issued 8 tickets per hour for 6 hours, then 5 tickets per hour for 3 additional hours. How many tickets were issued in total?

    Answer: 63

    (8 × 6) + (5 × 3) = 48 + 15 = 63 tickets issued in total.

  6. A department radio unit costs $3,600. If the department receives a 12.5% discount, what is the discounted cost per unit?

    Answer: $3,150

    Discount = 12.5% × $3,600 = $450; $3,600 − $450 = $3,150 per unit.

  7. A patrol schedule requires 4 deputies for morning shifts, 6 for afternoon shifts, and 5 for night shifts, seven days a week. How many total deputy-shifts are needed per week?

    Answer: 105

    (4 + 6 + 5) × 7 = 15 × 7 = 105 deputy-shifts per week.
