Question 2742

If three arithmetic means are inserted between 5 and 25, the second arithmetic mean is:

$10$
$15$✔️
$20$
None of these

Correct Answer Logic:

When three arithmetic means are inserted between 5 and 25, we have 5 terms total: 5, a₁, a₂, a₃, 25. Common difference $d = \frac{25-5}{4} = 5$. The terms are: 5, 10, 15, 20, 25. The second arithmetic mean is 15.

Civil / Architecture QUESTION #2337

Question 2744

According to Darcy's law, the seepage quantity $Q$ through a soil sample of cross-sectional area $A$, length $L$, head difference $\Delta h$ and permeability $k$ is:

$Q = k \cdot A \cdot \dfrac{L}{\Delta h}$
$Q = k \cdot \dfrac{\Delta h}{L} \cdot A$✔️
$Q = k \cdot \Delta h \cdot L \cdot A$
$Q = \dfrac{k \cdot A}{\Delta h \cdot L}$

Correct Answer Logic:

Darcy's law: $Q = k \cdot i \cdot A$ where the hydraulic gradient $i = \dfrac{\Delta h}{L}$. Therefore $Q = k \cdot \dfrac{\Delta h}{L} \cdot A$. This linear relationship is valid for laminar flow where velocity is directly proportional to hydraulic gradient.

Library Sciences QUESTION #1528

Question 2746

A 'union catalogue' differs from a single library's catalogue primarily because it:

Lists only rare and special collections
Records the combined holdings of multiple libraries, indicating which library owns each item✔️
Is published annually in print format only
Contains only bibliographic records without location information

Correct Answer Logic:

A union catalogue consolidates the holdings of two or more libraries into a single catalogue, with location symbols indicating which participating library owns each item. This is essential for interlibrary loan and cooperative collection development.

Question 2747

Once an action potential reaches the membrane of a skeletal muscle fiber, what is the first event in the contraction process?

Actin and myosin form a cross-bridge
Calcium is pumped back into the sarcoplasmic reticulum
Calcium is released from the sarcoplasmic reticulum✔️
ATP is hydrolyzed by troponin

Correct Answer Logic:

When an action potential arrives, it triggers the sarcoplasmic reticulum to release $Ca^{2+}$ ions, which bind to troponin, moving tropomyosin and allowing cross-bridge formation.

Question 2749

A drink contains 20% mango juice and the rest is apple juice. What is the ratio of mango juice to apple juice?

$4 : 1$
$1 : 4$✔️
$1 : 20$
None of these

Correct Answer Logic:

If the drink contains 20% mango juice, then it contains 80% apple juice (100% - 20% = 80%). The ratio of mango to apple juice is $20 : 80 = 1 : 4$. This means for every 1 part mango juice, there are 4 parts apple juice.

Question 2753

Under Section 61(1) [as amended 2023], the nomination deposit for election to the National Assembly is Rs. 30,000 and for Provincial Assembly is Rs. 20,000. What does Section 61(3) [as amended 2023] now provide regarding refundability of this deposit?

It is refunded if the candidate secures more than one-eighth of total votes polled
It is refunded only if the candidate wins the election
The sum deposited shall be non-refundable✔️
It is refunded upon submission of election expense return

Correct Answer Logic:

Section 61(3), as substituted by the Elections (Second Amendment) Act 2023, now states: 'The sum deposited shall be non-refundable' — eliminating the earlier refund provisions.

Tourism & Hospitality Management QUESTION #1610

Question 2755

In the Front Office Operations course, 'overbooking' is discussed as a front office practice. Which management strategy best justifies its controlled use?

To maximize staff utilization during quiet periods
To offset anticipated no-shows and cancellations, ensuring maximum occupancy and revenue while managing the risk of walking guests✔️
To provide discounted rooms to loyal customers
To manage tour group bookings separately from individual reservations

Correct Answer Logic:

Overbooking is addressed in Module 3 (Reservations and Check-in) of the Front Office Operations course. When practiced strategically, it is used to offset predictable no-show rates and last-minute cancellations — maximizing occupancy. The course covers its relationship with yield management and the front office procedures for managing 'walked' guests when overbooking results in excess arrivals.

Question 2757

In the context of geomorphic cycles, peneplains are most characteristically associated with which erosional stage?

Youth stage with maximum relief and steep slopes
Mature stage with well-developed drainage patterns
Old age stage approaching base level✔️
Rejuvenation phase with renewed downcutting

Correct Answer Logic:

Peneplains represent the final stage of Davis's geomorphic cycle - a nearly flat erosional surface approaching base level, characteristic of old age. Youth features steep slopes, maturity shows developed valleys, while rejuvenation restarts the cycle.

Physics QUESTION #1026

Question 2758

The kinetic energies of cars A and B are 100 J and 225 J. Car A stops after 1000 m and car B stops after 1500 m. The ratio $F_A/F_B$ is:

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

Correct Answer Logic:

By work-energy theorem: $F \cdot d = KE$. So $F_A = \frac{100}{1000} = 0.1\ \text{N}$ and $F_B = \frac{225}{1500} = 0.15\ \text{N}$. Ratio: $\frac{F_A}{F_B} = \frac{0.1}{0.15} = \frac{2}{3}$. Wait: $\frac{0.1}{0.15}=\frac{2}{3}$. Answer is option (4) = $\frac{2}{3}$... re-checking: $\frac{100/1000}{225/1500}=\frac{0.1}{0.15}=\frac{2}{3}$. Correct option index: 3.
