RCMP Numerical Reasoning and Computation 3

Question 1

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

Accepted Answer

84

Answer

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.

Question 2

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

Accepted Answer

$76,680

Answer

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

Question 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?

Accepted Answer

46 km

Answer

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

Question 4

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

Accepted Answer

84

Answer

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

Question 5

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

Accepted Answer

45 L

Answer

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