Commerce QUESTION #6079

The total of Konrad's purchases ledger balances was $57,400. Later, these errors were found:

Discount allowed overcast in cash book	$2,000
Returns outwards omitted in a supplier's account	$350
Payments to trade payables undercast in cash book	$137
Purchases journal overcast	$500

What is the corrected total of the trade payables balances?

$54,413
$54,913
$55,050
$57,050✔️

Correct Answer Logic:

Only errors affecting individual supplier accounts change the purchases ledger total.
1. Returns outwards omitted: $57,400 - $350 = $57,050.
The others (Discount allowed, payments undercast in cash book, journal overcast) affect the Control Account or other ledgers, but not the individual ledger balances until corrected there.

Farm size and mechanization level
Primary purpose of production (household consumption vs. market sale)✔️
Crop diversity and rotation practices

Physics QUESTION #1177

Question 5732

A photon having the same energy as an electron has wavelength __________ as electron's De Broglie wavelength.

Shorter
Longer✔️
Same
None of these

Correct Answer Logic:

For an electron: $\lambda_e = \frac{h}{\sqrt{2m_eE}}$. For a photon: $\lambda_{ph} = \frac{hc}{E}$. Ratio: $\frac{\lambda_{ph}}{\lambda_e} = \frac{hc}{E} \cdot \frac{\sqrt{2m_eE}}{h} = c\sqrt{\frac{2m_e}{E}}$. For typical energies, this ratio $\gg 1$, meaning the photon's wavelength is much longer than the electron's De Broglie wavelength at the same energy.

Mathematics QUESTION #978

Question 5734

Let $\alpha_\theta$ and $\beta_\theta$ be the distinct roots of $2x^2+(\cos\theta)x-1=0,\ \theta\in(0,2\pi)$. If $m$ and $M$ are the minimum and maximum values of $\alpha_\theta^4+\beta_\theta^4$, then $16(M+m)$ equals:

24
25✔️
17
27

Correct Answer Logic:

By Vieta's: $\alpha+\beta=-\frac{\cos\theta}{2}$, $\alpha\beta=-\frac{1}{2}$. Then $\alpha^2+\beta^2=(\alpha+\beta)^2-2\alpha\beta=\frac{\cos^2\theta}{4}+1$. And $\alpha^4+\beta^4=(\alpha^2+\beta^2)^2-2(\alpha\beta)^2=\left(\frac{\cos^2\theta}{4}+1\right)^2-\frac{1}{2}$. Let $u=\cos^2\theta\in[0,1]$. Max at $u=1$: $M=\frac{25}{16}-\frac{1}{2}=\frac{17}{16}$. Min at $u=0$: $m=1-\frac{1}{2}=\frac{1}{2}$. So $16(M+m)=16\cdot\frac{25}{16}=25$.

Physics QUESTION #1046

Question 5735

The output Y of the given logic circuit (NAND-NAND implementation) is similar to output of a ________ gate.

OR
NOR
AND✔️
NAND

Correct Answer Logic:

The circuit shows: A and B fed into a NAND gate, A also fed separately, and outputs combined into another NAND. Using Boolean algebra: NAND of two NANDs of (A,B) and (A,A) simplifies to AND. The output $Y = \overline{\bar{A}+\overline{AB}} = A\cdot B$ (AND gate).

Under Section 254(3) of the Companies Ordinance 1984, which of the following scenarios creates a legal disqualification for an auditor?

A person who was a director of the company 5 years ago
A person who is a Chartered Accountant with a QCR rating
A person whose spouse holds shares in the client company but fails to disinvest within 90 days✔️

Mathematics QUESTION #1259

Question 5739

Are the vectors $\mathbf{a}=(1,2,3)$, $\mathbf{b}=(2,5,7)$, $\mathbf{c}=(1,3,5)$ linearly dependent or independent?

Linearly independent
Linearly dependent✔️
Cannot be determined
Orthogonal

Correct Answer Logic:

Form the matrix and compute the determinant: $\begin{vmatrix}1&2&3\\2&5&7\\1&3&5\end{vmatrix} = 1(25-21)-2(10-7)+3(6-5) = 4-6+3=1 \neq 0$. Wait: $= 1(25-21)-2(10-7)+3(6-5)=4-6+3=1$. Det$\neq 0$ means linearly independent. Actually recomputing: $5\times5-7\times3=25-21=4$; $2\times5-7\times1=10-7=3$; $2\times3-5\times1=6-5=1$. Det$=1(4)-2(3)+3(1)=4-6+3=1\neq0$. Linearly independent.
