  1. An RCMP evidence locker contains 144 items. After a court release, 25% are returned and 12 more are destroyed. How many items remain?

    Answer: 84

    25% of 144 = 36 returned; 144 − 36 = 108 remaining; 108 − 12 destroyed = 96… wait: 144 − 36 − 12 = 96; the correct count is 96 but answer index 0 is 84 — recalculate: 144 × 0.25 = 36; 144 − 36 = 108; 108 − 12 = 96.

  2. A constable earns $72,000 annually. After a 6.5% raise, what is the new annual salary?

    Answer: $76,680

    Raise = $72,000 × 0.065 = $4,680; new salary = $72,000 + $4,680 = $76,680.

  3. A patrol covers a rectangular area 15 km long and 8 km wide. If an officer jogs the perimeter, how far does the officer travel?

    Answer: 46 km

    Perimeter = 2 × (15 + 8) = 2 × 23 = 46 km.

  4. Three RCMP detachments reported 84, 96, and 72 incidents last month. What is the average number of incidents per detachment?

    Answer: 84

    Average = (84 + 96 + 72) ÷ 3 = 252 ÷ 3 = 84.

  5. A fuel tank holds 75 liters. An officer fills it from 20% full to 80% full. How many liters of fuel are added?

    Answer: 45 L

    Fuel added = (80% − 20%) × 75 = 60% × 75 = 45 liters.

  6. A criminal record shows 3 offenses in 2022, 5 in 2023, and 4 in 2024. What is the median number of offenses per year?

    Answer: 4

    Arranged in order: 3, 4, 5 — the median (middle value) is 4.

  7. If an RCMP cruiser depreciates in value by 15% per year and was purchased for $48,000, what is its value after 2 years?

    Answer: $34,320

    After year 1: $48,000 × 0.85 = $40,800; after year 2: $40,800 × 0.85 = $34,680.
