The Constitution of Pakistan QUESTION #9342

Question 2

Under Article 48(1) as amended, the President is required to return advice for reconsideration within what period, and must act on the reconsidered advice within what period?

Seven days; five days
Fifteen days; ten days✔️
Ten days; fifteen days
Thirty days; ten days

Correct Answer Logic:

Article 48(1) proviso, as amended by the 18th Amendment, sets a 15-day window within which the President may require reconsideration, and then a 10-day window within which the President must act on the advice rendered after reconsideration. The sequence and asymmetry of these periods is frequently tested.

Question 3

Indexes and abstracts differ primarily in that abstracts:

Are always published annually while indexes are monthly
Provide a brief summary of the content of each document in addition to the citation✔️
Cover only books while indexes cover journals
Are restricted to government publications

Correct Answer Logic:

While both indexes and abstracts provide citations to documents, abstracts additionally include a brief summary (abstract) of each document's content, helping users assess relevance before retrieving the full text — saving time and effort.

Question 4

A car covers a certain distance at 60 km/h and returns at 40 km/h. What is the average speed for the entire journey?

48 km/h✔️
50 km/h
52 km/h
54 km/h

Correct Answer Logic:

Average speed for same distance at two speeds $= \dfrac{2 \times v_1 \times v_2}{v_1 + v_2} = \dfrac{2 \times 60 \times 40}{60 + 40} = \dfrac{4800}{100} = 48$ km/h.

Electrical Engineering QUESTION #2177

Question 5

A three-phase induction motor runs at $1440\,\text{rpm}$ on a $50\,\text{Hz}$ supply. The number of poles and percent slip are respectively:

4 poles, $4\%$✔️
6 poles, $4\%$
4 poles, $6\%$
8 poles, $4\%$

Correct Answer Logic:

Synchronous speed for $P = 4$: $N_s = \frac{120\times50}{4} = 1500\,\text{rpm}$. Slip $s = \frac{1500-1440}{1500}\times100 = 4\%$. For $P=6$: $N_s=1000\,\text{rpm}$, which would give negative slip — physically impossible.

Library Sciences QUESTION #1537

Question 6

Which management theory, associated with Frederick Winslow Taylor, emphasized scientific analysis of work tasks to maximize efficiency and is sometimes criticized for treating workers as machines?

Human Relations Theory
Systems Theory
Scientific Management Theory✔️
Contingency Theory

Correct Answer Logic:

Scientific Management (Taylorism) focused on analyzing and optimizing work processes through time-and-motion studies to maximize efficiency. Stueart & Moran (2007) note its limited applicability to library settings due to its mechanistic view of workers, which ignores motivation and job satisfaction.

Mathematics QUESTION #4145

Question 7

Solve $\frac{dy}{\sqrt{1-y^2}} = \frac{dx}{\sqrt{1-x^2}}$ with $y(0) = \frac{\sqrt{3}}{2}$. What is the solution?

$\sin^{-1}(y) = \sin^{-1}(x) + \frac{\pi}{3}$
$\sin^{-1}(y) = \sin^{-1}(x) + \frac{\pi}{6}$
$y = \sin(\sin^{-1}(x) + \frac{\pi}{3})$
Both (A) and (C)✔️

Correct Answer Logic:

Integrating: $\sin^{-1}(y) = \sin^{-1}(x) + C$. At $x=0$, $y=\frac{\sqrt{3}}{2}$: $\frac{\pi}{3} = 0 + C$, so $C = \frac{\pi}{3}$. Thus $\sin^{-1}(y) = \sin^{-1}(x) + \frac{\pi}{3}$, equivalent to $y = \sin(\sin^{-1}(x) + \frac{\pi}{3})$.

Question 9

Which protocol enables interoperability between different library systems by allowing one system to query the catalogues of another using a standard search interface?

HTTP
FTP
Z39.50✔️
SMTP

Correct Answer Logic:

Z39.50 is a client-server protocol that enables one library system (client) to search and retrieve records from another system's database (server) using a standardized interface. It is fundamental to union catalogue searching, shared cataloguing, and federated search systems.

Question 11

'Equivalent Evaporation' is a standard used to compare boilers, defined from and at:

$100^\circ\text{C}$✔️
$0^\circ\text{C}$
$200^\circ\text{C}$
Room temperature

Correct Answer Logic:

It calculates evaporation 'from and at $100^\circ\text{C}$' to normalize different operating pressures/temps.

Mathematics QUESTION #6006

Question 12

Given $(2 + \sin x)\dfrac{dy}{dx} + (y+1)\cos x = 0$ with $y(0) = 1$, find the value of $y\!\left(\dfrac{\pi}{2}\right)$.

$\dfrac{1}{3}$✔️
$-\dfrac{2}{3}$
$-\dfrac{1}{3}$
$\dfrac{4}{3}$

Correct Answer Logic:

Separate variables: $\frac{dy}{y+1} = -\frac{\cos x}{2+\sin x}dx$

Integrate: $\ln|y+1| = -\ln|2+\sin x| + C$

So $(y+1)(2+\sin x) = K$

At $x=0, y=1$: $(1+1)(2+0) = K \Rightarrow K = 4$

Thus $y+1 = \frac{4}{2+\sin x}$, so $y = \frac{4}{2+\sin x} - 1$

At $x = \frac{\pi}{2}$: $y = \frac{4}{2+1} - 1 = \frac{4}{3} - 1 = \mathbf{\frac{1}{3}}$

Law QUESTION #9473

Question 13

In a suit for partition of an ancestral house jointly owned by siblings A, B and C, the trial Court passes a preliminary decree. C dies before the final decree is passed, leaving a minor son D as legal heir. A applies for the suit to proceed. B argues the suit has abated due to C's death before the final decree. What is the correct legal position?

The suit continues; D as C's legal representative steps into C's shoes and the proceedings carry on✔️
The suit must be filed afresh including D as a party
The suit abates as C died before the final decree
The preliminary decree becomes final upon C's death

Correct Answer Logic:

Under Section 50 CPC read with Order XXII, where a party dies before a decree is fully satisfied or proceedings are concluded, the legal representative steps in. The suit does not abate merely because a party dies at an intermediate stage. D, as C's legal heir, must be brought on record and the suit continues.
