Question 1 (Arithmetic Reasoning)
A military storage depot has a total of 1,200 uniforms. If 35% of the
uniforms are allocated to the Army, 40% to the Navy, and the remaining
uniforms are allocated to the Air Force, how many uniforms does the Air
Force receive?
A) 300 uniforms
B) 420 uniforms
C) 480 uniforms
D) 540 uniforms
Answer: A) 300 uniforms
Rationale:
First, calculate the total percentage allocated to the Army and Navy
combined: 35% + 40% = 75%. This leaves 25% for the Air Force (100% -
,75% = 25%). To find the exact number of uniforms the Air Force receives,
calculate 25% of 1,200. Since 25% is equal to one-quarter (1/4), divide
1,200 by 4, which equals 300 uniforms.
Question 2 (General Science)
Which layer of the Earth's atmosphere contains the ozone layer, which
protects organisms from harmful ultraviolet (UV) radiation?
A) Troposphere
B) Stratosphere
C) Mesosphere
D) Thermosphere
Answer: B) Stratosphere
Rationale:
The stratosphere is the second major layer of Earth's atmosphere, located
directly above the troposphere. It contains the ozone layer (ozonosphere),
which absorbs and scatters solar ultraviolet radiation. The troposphere is
where weather occurs, the mesosphere is where meteors burn up, and the
thermosphere contains the ionosphere.
Question 3 (Word Knowledge)
Choose the word that is closest in meaning to the underlined word: The
sergeant gave a concise briefing regarding the upcoming night patrol
operations.
A) Lengthy
B) Brief
C) Ambiguous
D) Detailed
Answer: B) Brief
Rationale:
The word "concise" means giving a lot of information clearly and in a few
words; brief but comprehensive. Therefore, "Brief" is the closest synonym.
"Lengthy" and "Detailed" imply long duration or wordiness, while
"Ambiguous" means unclear or open to multiple interpretations.
,Question 4 (Paragraph Comprehension)
Read the passage below:
"The dynamic nature of cyber warfare requires military personnel to be
perpetually vigilant. Traditional physical borders no longer define the front
lines of conflict. Instead, critical infrastructure, financial institutions, and
communications networks are vulnerable to remote incursions from state-
sponsored entities and independent hackers alike."
Based on the passage, which of the following statements is most accurate?
A) Front lines of modern conflict are strictly limited to physical land borders.
B) Cyber attacks only target financial institutions and ignore infrastructure.
C) Modern military defense must adapt to threats that cross non-physical boundaries.
D) Independent hackers are the only threat to national communications networks.
Answer: C) Modern military defense must adapt to threats that cross non-
physical boundaries.
Rationale:
The passage explicitly states that traditional physical borders no longer
define the front lines and that digital infrastructure is vulnerable to remote
incursions. This directly supports the idea that defense must adapt to non-
physical boundaries. Option A is contradicted by the text, Option B is
inaccurate because infrastructure is also targeted, and Option D is incorrect
because state-sponsored entities are also mentioned.
Question 5 (Mathematics Knowledge)
What is the value of \(x\) in the algebraic equation: \(4x - 7 = 2x + 15\)?
A) \(x = 4\)
B) \(x = 7\)
C) \(x = 11\)
D) \(x = 22\)
Answer: C) x = 11
Rationale:
To solve for \(x\), first isolate the variable terms on one side of the equation
by subtracting \(2x\) from both sides: \(4x - 2x - 7 = 15\), which simplifies to
\(2x - 7 = 15\). Next, add 7 to both sides of the equation: \(2x = 15 + 7\),
, which gives \(2x = 22\). Finally, divide both sides by 2: \(x = \),
resulting in \(x = 11\).
Question 6 (Mechanical Comprehension)
A mechanic uses a pair of heavy-duty pliers to cut through a thick copper
wire. If the mechanic grips the handles further away from the pivot point
(fulcrum), what effect does this have on the force applied to the wire?
A) The cutting force at the jaws decreases.
B) The cutting force at the jaws increases.
C) The friction inside the pivot point decreases to zero.
D) The mechanical advantage shifts to a third-class lever.
Answer: B) The cutting force at the jaws increases.
Rationale:
Pliers operate as a first-class lever system. Mechanical advantage
increases when the length of the effort arm (distance from the hand to the
pivot) increases relative to the resistance arm (distance from the pivot to
the wire). Gricking further out creates a longer effort arm, multiplying the
force exerted at the cutting jaws.
Question 7 (Electronics Information)
Which electronic component is primarily used to store an electric charge
temporarily within a circuit and block the flow of Direct Current (DC) while
allowing Alternating Current (AC) to pass?
A) Resistor
B) Transistor
C) Inductor
D) Capacitor
Answer: D) Capacitor
Rationale:
A capacitor consists of two conductive plates separated by an insulating
material (dielectric) and functions to store electrical energy in an
electrostatic field. In a circuit, it blocks constant DC voltage once fully
