Mathematics QUESTION #1301

Question 125

The characteristic equation of $3y''-6y'+6y=0$ has roots:

$r=1\pm i$✔️
$r=1\pm 2i$
$r=-1\pm i$
$r=2\pm i$

Correct Answer Logic:

Dividing by 3: $y''-2y'+2y=0$. Characteristic equation: $r^2-2r+2=0\Rightarrow r=\dfrac{2\pm\sqrt{4-8}}{2}=\dfrac{2\pm 2i}{2}=1\pm i$. Complementary solution: $y_c=e^x(C_1\cos x+C_2\sin x)$.

Maths QUESTION #4575

Question 126

Average of $5, 10, 15$ is $A$. If $20$ is added, what is the new average?

$10$
$12.5$✔️
$15$
$A + 20$

Correct Answer Logic:

Old average = $\frac{5+10+15}{3} = 10$. New average = $\frac{5+10+15+20}{4} = \frac{50}{4} = 12.5$

Question 128

To express 2.08 in terms of percentage, one gets:

$208\%$✔️
$20\%$
$20.8\%$
None of these

Correct Answer Logic:

To convert a decimal to percentage, multiply by 100. Therefore, $2.08 \times 100 = 208\%$. This means 2.08 is equivalent to 208 percent.

Education QUESTION #6908

Question 129

Which of the following is a KEY distinction between 'school culture' and 'school climate' in the context of school-wide discipline and effective management?

School culture refers to academic outcomes while climate refers to physical environment
School culture is the deep, accumulated stream of norms, values, beliefs, and traditions built over time, while climate refers to the immediate social and emotional atmosphere that students and staff experience day to day✔️
School culture is determined by government policy while climate is determined by teachers
School culture changes annually while climate is permanent

Correct Answer Logic:

School culture is deep, historically accumulated, and slow to change — it is the bedrock of shared assumptions, traditions, and values. School climate is more immediate and perceptible — it is what people feel walking into a school on a given day. Both are important to classroom management, but culture provides the foundational conditions from which climate emerges.

Physics QUESTION #1167

Question 130

What is NOT the condition for equilibrium in a three-dimensional system?

$\sum F_x = 0$
$\sum F_y = 0$
$\sum F_z = 0$
$\sum F \neq 0$✔️

Correct Answer Logic:

For a body to be in equilibrium in three dimensions, the net force in every direction must be zero: $\sum F_x = 0$, $\sum F_y = 0$, and $\sum F_z = 0$. The condition $\sum F \neq 0$ violates equilibrium (it means there is a net unbalanced force), so it is NOT a condition for equilibrium.

Accounting & Finance QUESTION #6162

Question 131

Which financial indicator is considered a 'cumulative' measure of management's success in adding value since the firm's inception?

Economic Value Added (EVA)
Net Income
Market Value Added (MVA)✔️
Return on Equity (ROE)

Correct Answer Logic:

According to Lesson 03, MVA is a cumulative measure of wealth added to equity capital since inception, whereas EVA is for a specific year.

Moisture makes the drug too heavy
Moisture turns the drug into a liquid
There is no problem

Correct Answer Logic:

Crude drugs must be dried to prevent chemical breakdown and spoilage.

Tourism & Hospitality Management QUESTION #1598

Question 133

Which of the following statements about the CPEC (China-Pakistan Economic Corridor) is correctly identified in the Pakistan Tourist Destinations course as a benefit to tourism?

CPEC is expected to damage Pakistan's natural tourist sites through industrialization
CPEC infrastructure development (roads, energy, connectivity) is expected to enhance tourism accessibility and create new investment opportunities in Pakistan's tourist destinations✔️
CPEC has no relevance to tourism development in Pakistan
CPEC focuses exclusively on industrial development with no tourism component

Correct Answer Logic:

The Pakistan Tourist Destinations course lists 'CPEC and benefits to Tourism Industry' under the Neotourism module, recognizing that CPEC's infrastructure development — improved roads, connectivity, and economic investment — creates new opportunities for tourism accessibility, accommodation investment, and regional destination development in Pakistan.

Question 134

Which generation of computers introduced transistors to replace vacuum tubes?

Fourth
Third
Second✔️
First

Correct Answer Logic:

Second Generation computers (1956–1963) replaced vacuum tubes with transistors, invented at Bell Labs in 1947. Transistors were smaller, faster, cheaper, more reliable, and consumed less power. Examples: IBM 7094, UNIVAC 1107. Third generation used ICs; fourth used microprocessors.

HR and Management QUESTION #6443

Question 135

In anti-defection strategies against brain drain, Compaq Computer's policy involves:

Higher base salaries for all employees
Revoking bonuses and benefits to executives who take other employees when they quit✔️
Non-compete agreements lasting 5 years
Stock options vesting over 10 years

Correct Answer Logic:

To combat brain drain, Compaq introduced a policy that revokes bonuses and other benefits to key executives if they take other employees with them when they quit. This prevents key personnel from causing further damage by recruiting talent when leaving.

The Constitution of Pakistan QUESTION #9339

Question 136

Under Article 6(2A) of the Constitution, which courts are expressly barred from validating an act of high treason?

Only the Supreme Court
Only the High Courts
The Federal Constitutional Court, the Supreme Court, and all High Courts✔️
Only the Federal Constitutional Court

Correct Answer Logic:

Article 6(2A) (inserted by the 18th Amendment and later updated by the 27th Amendment) explicitly states that an act of high treason 'shall not be validated by any court including the Federal Constitutional Court, Supreme Court and a High Court.' This is a constitutional safeguard against judicial legitimization of coups or unconstitutional takeovers.

MBBS QUESTION #10371

Question 137

The polymerase chain reaction (PCR), used to exponentially amplify a specific target DNA sequence in vitro, consists of which three essential, repeated cyclic steps?

Denaturation (strand separation), annealing (primer binding), and extension (elongation)✔️
Transcription, translation, and replication
Ligation, restriction enzyme digestion, and gel electrophoresis
Centrifugation, filtration, and chemical precipitation

Correct Answer Logic:

Each PCR cycle involves heat denaturation of double-stranded DNA, annealing of short complementary primers to the target sequence at a lower temperature, and extension of new DNA strands by a heat-stable DNA polymerase (e.g., Taq polymerase) — repeated cycles exponentially amplify the target sequence, forming the basis of modern molecular diagnostics.

Question 138

Who invented the punch card system for mechanical data processing?

Powers
Pascal
Herman Hollerith✔️
Jacquard

Correct Answer Logic:

Herman Hollerith invented the punched card tabulating machine in 1890 for the US Census. His company later became part of IBM. Joseph Marie Jacquard earlier used punched cards to control looms (1804), but Hollerith's adaptation for data processing is the direct precursor to modern computing punch card systems.

Accounting & Finance QUESTION #9659

Question 139

A firm's goods are sold at a margin of 25% on sales. Purchases = Rs. 155,000; Opening Stock = Rs. 10,000; Closing Stock = Rs. 15,000. What are total Sales?

Rs. 200,000✔️
Rs. 150,000
Rs. 187,500
Rs. 175,000

Correct Answer Logic:

COGS = 10,000 + 155,000 – 15,000 = Rs. 150,000. Margin = 25%, so COGS = 75% of Sales. Sales = 150,000 × 100/75 = Rs. 200,000. The margin formula: Sales = COGS/(1 – Margin%) = 150,000/0.75.

Civil Engineering QUESTION #2125

Question 140

Bernoulli's equation for steady, incompressible, inviscid flow along a streamline is $\dfrac{p}{\rho g} + \dfrac{V^2}{2g} + z = \text{constant}$. The term $\dfrac{V^2}{2g}$ represents:

Pressure head
Velocity head (kinetic energy per unit weight of fluid)✔️
Elevation head
Total energy head

Correct Answer Logic:

In Bernoulli's equation, each term has units of length (head): $\dfrac{p}{\rho g}$ = pressure head; $\dfrac{V^2}{2g}$ = velocity head (kinetic energy per unit weight); $z$ = elevation (potential energy per unit weight); total = piezometric + velocity head = total energy head. Velocity head represents kinetic energy — it converts to pressure head at stagnation points (Pitot tube principle).
