Three months before the date of notification
The date of approval by the Provincial Assembly
Such date as may be specified in the notification, but not prior to the date on which the notification is PUBLISHED in the Official Gazette✔️
The first day of the next financial year

Section 5(2) provides a strict rule: the notification shall be effective from such date as may be specified therein, but SUCH DATE SHALL NOT BE PRIOR TO THE DATE ON WHICH THE NOTIFICATION IS PUBLISHED in the official Gazette — preventing retrospective taxation through subordinate legislation.

Physics QUESTION #7072

Question 7

Two radioactive isotopes, $A$ and $B$, have half-lives of $20$ minutes and $40$ minutes, respectively. If both samples start with an identical number of nuclei, determine the ratio of the number of decayed nuclei of $A$ to those of $B$ after a period of $80$ minutes.

$4:1$
$1:4$
$5:4$✔️
$1:16$

Correct Answer Logic:

After $80$ minutes, $A$ undergoes $4$ half-lives ($80/20$), leaving $N_A = N_0/2^4 = N_0/16$. The number of decayed nuclei for $A$ is $N_0 - N_0/16 = 15N_0/16$. $B$ undergoes $2$ half-lives ($80/40$), leaving $N_B = N_0/2^2 = N_0/4$. The number of decayed nuclei for $B$ is $N_0 - N_0/4 = 3N_0/4 = 12N_0/16$. The ratio of decayed nuclei is $15:12$, which simplifies to $5:4$.

Accounting & Finance QUESTION #6052

Question 8

Which one of the following qualifies as a capital expenditure?

Paying for renovations that upgrade and improve a building✔️
Paying carriage-outward charges related to delivering sold goods
Paying legal fees to recover outstanding amounts from customers
Paying performance bonuses to production workers

Correct Answer Logic:

Capital expenditure is spending that improves, extends the life of, or adds value to a long-term asset. Renovating and upgrading a building increases its value and useful life — this is capital expenditure. The other options are all revenue expenditures: carriage outwards, legal recovery fees, and wage bonuses are period costs that appear on the income statement and do not create lasting assets.

Library Sciences QUESTION #1559

Question 9

The principle of 'hospitality' in classification refers to:

The welcoming attitude of library staff toward users
The capacity of a classification system to accommodate new subjects without disrupting the existing notation✔️
The practice of providing comfortable reading spaces
The cooperation between libraries in sharing resources

Correct Answer Logic:

Hospitality in classification theory means a system's ability to insert new subjects, disciplines, or topics into the existing structure without requiring fundamental reorganization. DDC and UDC are considered more hospitable than older enumerative systems because of their faceted and hierarchical structure.

Physics QUESTION #7342

Question 10

A projectile has initial velocity $(2\hat{i}+3\hat{j})\text{ m/s}$ at point A (at ground level). At point B (on the x-axis, same height as A), its velocity is:

$2\hat{i}+3\hat{j}$
$-2\hat{i}-3\hat{j}$
$-2\hat{i}+3\hat{j}$
$2\hat{i}-3\hat{j}$✔️

Correct Answer Logic:

Horizontal component is unchanged throughout: $v_x = 2\text{ m/s}$.

When the projectile returns to the same height, the vertical component reverses: $v_y = -3\text{ m/s}$.

Velocity at B $= \mathbf{2\hat{i} - 3\hat{j}}$

Verbal Reasoning QUESTION #8100

Question 13

Compare the two quantities below.

Column A: $9^7$

Column B: $10{,}000{,}000$

Column A is greater
Column B is greater✔️
The two quantities are equal
The relationship cannot be determined from the information given

Correct Answer Logic:

Note that $10{,}000{,}000 = 10^7$.

Comparing $9^7$ vs $10^7$: since the base $9 < 10$ and both exponents are equal and positive, we have $9^7 < 10^7$.

Therefore Column B ($10^7$) is greater than Column A ($9^7$).

Chemistry QUESTION #5568

Question 15

An organic compound A reacts with $NH_3$ to give B. On heating, B gives C. C reacts with $Br_2$/KOH to give $CH_3CH_2NH_2$ (ethylamine). Identify compound A.

$CH_3COOH$
$CH_3CH_2CH_2COOH$
$CH_3CH(CH_3)COOH$ (2-methylpropanoic acid)
$CH_3CH_2COOH$✔️

Correct Answer Logic:

Working backwards: $CH_3CH_2NH_2$ (ethylamine) is produced by Hofmann bromamide degradation of $CH_3CH_2CONH_2$ (propionamide). Propionamide (C) is produced by heating propanoic acid ammonium salt (B). B is formed when $CH_3CH_2COOH$ (propanoic acid = A) reacts with $NH_3$. So A = $CH_3CH_2COOH$.

Physics QUESTION #994

Question 16

Assertion (A): A simple pendulum taken to a planet with mass 4 times and radius 2 times that of Earth has the same time period. Reason (R): The mass of the pendulum remains unchanged on Earth and the planet.

(A) is false but (R) is true
(A) is true but (R) is false
Both (A) and (R) are true and (R) is the correct explanation of (A)
Both (A) and (R) are true but (R) is NOT the correct explanation of (A)✔️

Correct Answer Logic:

Planet's $g' = \frac{GM'}{R'^2} = \frac{G\cdot4M}{(2R)^2} = \frac{4GM}{4R^2} = g$. So time period $T=2\pi\sqrt{L/g}$ remains same — (A) is true. (R) is also true but the reason is equal $g$, not unchanged mass. So (R) is not the correct explanation.

Civil Procedure QUESTION #3746

Question 17

An individual wants to sue the government to challenge a new law that increases taxes on gasoline. The individual's only injury is that they pay $\text{\$50}$ more per year for gas. Does the individual have standing?

Yes, any taxpayer has standing to challenge any tax.
No, because the injury is a 'generalized grievance' shared by millions of others.✔️
Yes, because $\text{\$50}$ is a concrete 'injury in fact.'
No, because taxes are 'political questions.'

Correct Answer Logic:

Taxpayers generally lack standing to challenge government spending or taxing unless they can show a specific, concrete, and individualized injury. A small increase in gas tax shared by all drivers is a generalized grievance.

Question 18

If $5x^2 - 4x - 1$ is divided by $(x - 1)$, the remainder is:

2
1
None

By the Remainder Theorem, substitute $x = 1$:
$5(1)^2 - 4(1) - 1 = 5 - 4 - 1 = 0$
Remainder $= 0$.

Chemistry QUESTION #7110

Question 19

Given the half-cell reactions:
1. $Mn^{2+} + 2e^{-} \rightarrow Mn$; $E^{0} = -1.18\text{ V}$
2. $Mn^{3+} + e^{-} \rightarrow Mn^{2+}$; $E^{0} = +1.51\text{ V}$
Determine the $E^{0}$ for the disproportionation reaction $3Mn^{2+} \rightarrow Mn + 2Mn^{3+}$ and its feasibility.

-0.33 V; non-spontaneous
-0.33 V; spontaneous
-2.69 V; non-spontaneous✔️
-2.69 V; spontaneous

Correct Answer Logic:

The target reaction is $3Mn^{2+} \rightarrow Mn + 2Mn^{3+}$. This is the sum of:
Reduction: $Mn^{2+} + 2e^{-} \rightarrow Mn$ ($E^{0}_{red} = -1.18\text{ V}$)
Oxidation: $2Mn^{2+} \rightarrow 2Mn^{3+} + 2e^{-}$ ($E^{0}_{ox} = -1.51\text{ V}$)
$E^{0}_{cell} = E^{0}_{cathode} - E^{0}_{anode} = -1.18 - 1.51 = -2.69\text{ V}$. Since $E^{0}_{cell}$ is negative, the reaction is non-spontaneous.
