For x > 0, what is the minimum value of x + 16/x?
- a)4
- b)8 (correct answer)
- c)12
- d)16
Answer and explanation
Correct answer: (b) 8
- AM–GM for positive numbers: x + 16/x ≥ 2√(x · 16/x) = 2√16 = 8.
- Equality when x = 16/x, i.e. x = 4: 4 + 4 = 8.
Check by calculus: f′(x) = 1 − 16/x² = 0 gives x = 4 and f(4) = 8.
Other options: (a) 4 — the value of x at the minimum, not the minimum value; (c) 12 — reached at x ≈ 1.53 or 10.47, above the least value; (d) 16 — reached at x ≈ 1.07 or 14.93, also above it.
Also know:
- For x > 0 and k > 0, x + k/x ≥ 2√k, with equality at x = √k.
- For x < 0 the expression is at most −8 (a maximum, at x = −4).
- AM ≥ GM, with equality only when the numbers are equal.

In a class, Rahim ranks 7th from the top and 26th from the bottom. How many students are in the class?
- a)32 (correct answer)
- b)35
- c)37
- d)40
Answer and explanation
Correct answer: (a) 32
- Rank from top + rank from bottom counts Rahim twice.
- Total = 7 + 26 − 1 = 32.
Check: 6 students above him + Rahim + 25 below him = 32.
Other options: (b) 35, (c) 37 and (d) 40 — each is more than 32, but the ranks give only 6 above + Rahim + 25 below, so no extra students exist.
Also know:
- Total = (rank from top) + (rank from bottom) − 1.
- Rank from bottom = Total − (rank from top) + 1.
- When two people's ranks are given, count the people between them carefully and do not double-count.
Sources: calc: 6 above + Rahim + 25 below (working above).

A progressive tax system is one in which:
- a)Everyone pays the same fixed tax amount
- b)The tax rate decreases as income increases
- c)Tax is levied only on corporate profits
- d)The tax rate increases as income increases (correct answer)
Answer and explanation
Correct answer: (d) The tax rate increases as income increases
The US IRS defines a progressive tax as one that takes a larger percentage of income from high-income groups than from low-income groups — the rate rises with income, so those able to pay more pay more.
Other options: (a) Everyone pays the same fixed tax amount — a lump-sum (poll) tax, which takes a bigger share from the poor; (b) The tax rate decreases as income increases — a regressive tax; (c) Tax is levied only on corporate profits — a corporate income tax, a tax base, not a rate structure.
Also know:
- A proportional (flat) tax charges the same percentage at every income level.
- Progressive taxes rest on the ability-to-pay principle.
- Personal income tax with rising slab rates is the classic progressive tax.

A type of malicious software that infects computer systems, encrypts files, or locks users out of their devices is called –
- a)Ransomware (correct answer)
- b)Trojan horse
- c)XSS injection
- d)Denial of Service (DoS)
Answer and explanation
Correct answer: (a) Ransomware
Ransomware is malware designed to encrypt files on a device, making the files and the systems that rely on them unusable; the attackers then demand a ransom in exchange for decryption.
Other options: (b) Trojan horse — a program that appears useful but hides a malicious function; the term describes the disguise, not encryption for ransom; (c) XSS injection — a web-application flaw in which malicious scripts are injected into trusted websites and run in visitors' browsers; (d) Denial of Service (DoS) — preventing authorized access to resources or delaying time-critical operations; it attacks availability without encrypting the victim's files.
Also know:
- Ransomware actors often also steal data and threaten to sell or leak it if the ransom is not paid.
- OWASP classifies Cross-Site Scripting as a type of injection attack.
- NIST publishes a Cybersecurity Framework (CSF) Ransomware Profile to help organizations manage ransomware risk.

Correct answer: (b) Phishing
Phishing tries to acquire sensitive data, such as bank account numbers, through a fraudulent solicitation in e-mail or on a web site, the attacker masquerading as a legitimate business or reputable person. CISA: the bait may also be a text, social-media message or phone call.
Other options: (a) Man-in-the-middle — the attacker is positioned between two communicating parties to intercept and/or alter the data travelling between them; (c) Eavesdropping — the attacker obtains a secret as it is being entered or sent (NIST's examples: watching keyboard entry, keystroke logging) rather than tricking the victim into handing it over; (d) SQL injection — inserting a SQL query through an application's input data to read or modify its database; it attacks the application, not the person.
Also know:
- NIST's definition of phishing is taken from IETF RFC 4949.
- In authentication, a man-in-the-middle sits between the claimant and the verifier.
- A successful SQL injection can read sensitive data and insert, update or delete database data.

What is the name of the firmware embedded on the motherboard that initializes hardware components during the booting process before loading the operating system?
- a)BIOS / UEFI (correct answer)
- b)CMOS Battery
- c)Kernel
- d)Chipset Driver
Answer and explanation
Correct answer: (a) BIOS / UEFI
The system BIOS — or its modern replacement UEFI — is the boot firmware: the first software executed on the CPU at power-on. Per NIST SP 800-147 it:
- Initializes and tests low-level hardware (the Power-On Self-Test, POST): motherboard, chipset, memory and CPU.
- Selects a boot device and executes its boot loader.
- The boot loader loads the OS kernel, and control passes to the operating system.
Other options: (b) CMOS battery — a battery on the motherboard (hardware, not firmware) that powers the CMOS chip storing settings such as date, time and boot order; (c) Kernel — the operating-system kernel, which the boot loader loads only after the firmware's work; (d) Chipset driver — a software component that lets the OS and a device communicate, so it works through the OS rather than as boot firmware.
Also know:
- Firmware means programs and data stored in hardware such as ROM or PROM, not dynamically written during execution.
- If the CMOS battery loses power, stored settings such as the system date and time may be lost.

The keyboard keys 'Shift', 'Ctrl', and 'Alt' are called –
- a)Function Key
- b)Numeric Key
- c)Decoder Key
- d)Modifier Key (correct answer)
Answer and explanation
Correct answer: (d) Modifier Key
Modifier keys are special keys used in combination with other keys to generate special characters or cause special actions; MDN's modifier-key list includes Shift, Control (Ctrl) and Alt. For example, Ctrl+C copies the selected text and Ctrl+V pastes it.
Other options: (a) Function Key — the general-purpose keys such as F1–F12, which MDN lists as a separate group from the modifiers; (b) Numeric Key — the digit keys and the numeric keypad group, not Shift, Ctrl or Alt; (c) Decoder Key — not a group of keys in MDN's key-value list.
Also know:
- MDN also lists lock keys such as Caps Lock and Num Lock among the modifier keys.
- MDN also lists AltGr (Alternate Graphics) and Fn (Function modifier) as modifier keys.
