1. A soldier is reviewing basic arithmetic required for MOS classification
testing. If a maintenance task requires 3.5 hours per unit and 6 units
must be completed, how many total hours are required to complete
the task?
A. 18 hours
B. 19 hours
C. 21 hours
D. 24 hours
The total time is found by multiplying 3.5 hours per unit by 6 units,
resulting in 21 hours, which is the correct total workload required.
2. A technical manual states that a fuel system operates efficiently at a
ratio of 5:2 (fuel to air). If 20 liters of fuel are used, how much air is
required?
A. 6 liters
B. 8 liters
C. 10 liters
D. 12 liters
, The ratio 5:2 means for every 5 units of fuel, 2 units of air are
required; scaling up from 20 liters of fuel gives 8 liters of air.
3. A technician measures resistance in a circuit at 12 ohms and voltage at
24 volts. What is the current according to Ohm’s Law?
A. 1 amp
B. 2 amps
C. 3 amps
D. 4 amps
Using I = V/R, the current equals 24 divided by 12, resulting in 2
amps.
4. A soldier reads a map scale where 1 cm represents 2 km. If two points
are 7 cm apart, what is the real distance?
A. 10 km
B. 12 km
C. 14 km
D. 16 km
Multiplying 7 cm by the scale factor of 2 km per cm gives a real-world
distance of 14 km.
5. A maintenance log shows 45 minutes per inspection. How many
inspections can be completed in 6 hours?
A. 6
B. 7
C. 8
D. 9
Six hours equals 360 minutes; dividing by 45 minutes per inspection
yields 8 inspections.
6. A unit must reduce equipment weight from 120 kg by 25%. What is the
new weight?
A. 80 kg
, B. 90 kg
C. 95 kg
D. 100 kg
A 25% reduction of 120 kg is 30 kg, leaving a remaining weight of 90
kg.
7. A soldier completes 18 tasks in 3 hours. What is the average rate per
hour?
A. 4 tasks/hour
B. 6 tasks/hour
C. 7 tasks/hour
D. 9 tasks/hour
Dividing 18 tasks by 3 hours gives an average rate of 6 tasks per
hour.
8. In electronics, a circuit has a voltage of 9V and resistance of 3 ohms.
What is the current?
A. 1 amp
B. 2 amps
C. 3 amps
D. 4 amps
Using Ohm’s Law, 9 divided by 3 equals 3 amps.
9. A coded message replaces each letter with the next letter in the
alphabet. What does “DBU” decode to?
A. CAT
B. CAT
C. BAT
D. CAR
Shifting each letter back one step transforms D→C, B→A, U→T,
forming CAT.
