Accounting & Finance QUESTION #6094

Question 5102

P Limited produces chairs at $70 each. It receives a special order for 1,000 chairs with padded seats. This requires $6,000 in extra materials, 500 extra labour hours at $15/hour, and $2,000 extra overheads. What is the total cost of this batch?

$13,500
$15,500
$83,500
$85,500✔️

Correct Answer Logic:

1. Base cost = 1,000 $\times$ $70 = $70,000.
2. Extra materials = $6,000.
3. Extra labour = 500 $\times$ $15 = $7,500.
4. Extra overheads = $2,000.
Total = $70,000 + $6,000 + $7,500 + $2,000 = $85,500.

Law QUESTION #9501

Question 5105

The trial Court in a civil suit, after full trial, passes a judgment. The losing party B files an appeal. The appellate Court, without conducting a hearing on merits, reverses the trial Court's decree only because it disagrees with the trial Court's findings of fact, without identifying any specific perversity or misreading of evidence. Is this valid appellate exercise?

Yes; an appellate Court can freely re-appreciate evidence
No; an appellate Court can reverse only on questions of law
Yes; a first appeal is a rehearing on facts and law
No; while an appellate Court can re-appreciate evidence, reversal requires more than mere disagreement; the appellate Court must assign reasons for disagreeing with the trial Court's findings and identify how the evidence was misread or ignored✔️

Correct Answer Logic:

The CPC and settled principles of appellate jurisprudence require that a first appellate Court, while having jurisdiction to reassess evidence, must not substitute its own findings for those of the trial Court without adequate reasons. Reversal on facts requires the appellate Court to demonstrate perversity, misreading, or improper appreciation of evidence, not mere disagreement.

Boilers Mechanical Engineering QUESTION #2464

Question 5106

For a power screw, the efficiency $e$ is defined as the ratio of the ideal torque (frictionless) to the actual raising torque. For a square thread, $e$ equals:

$e = \frac{Fl}{2\pi T_r}$✔️
$e = \frac{T_r}{T_0}$
$e = \mu\tan\lambda$
$e = \frac{\pi d_m}{l}$

Correct Answer Logic:

The ideal (frictionless) torque to raise load $F$ through one revolution is $T_0=Fl/(2\pi)$. Efficiency: $e=T_0/T_r=Fl/(2\pi T_r)$.

Mathematics QUESTION #11142

Question 5107

$\displaystyle\lim_{z\to 0}\frac{\bar{z}}{z}=$

$\dfrac{1+i}{1-i}$
$1$
Does not exist✔️
$-1$

Correct Answer Logic:

Write $z = re^{i\theta}$, so $\bar{z} = re^{-i\theta}$ and $\bar{z}/z = e^{-2i\theta}$. As $z\to 0$ along different paths (different $\theta$), the limit takes different values. For example, along the real axis ($\theta=0$): limit $= 1$; along the imaginary axis ($\theta=\pi/2$): limit $= e^{-i\pi} = -1$. Since the limit depends on the path, $\displaystyle\lim_{z\to 0}\frac{\bar{z}}{z}$ does not exist.

Boilers Mechanical Engineering QUESTION #4019

Question 5108

The 'Boiling Point' of water inside a boiler at $10~bar$ pressure is:

Exactly $100^\circ\text{C}$
Higher than $100^\circ\text{C}$✔️
Lower than $100^\circ\text{C}$
The same as at sea level

Correct Answer Logic:

As pressure increases, the boiling temperature of water also increases.

Question 5110

'Starch' grains can be identified under a microscope by their characteristic:

Color
Hilum and Striations✔️
Weight
Taste

Correct Answer Logic:

The shape and position of the hilum help identify the source of starch (e.g., Potato vs Maize).

Physics QUESTION #997

Question 5111

A tube of length $L$ has radius 2 cm at point (1) and 1 cm at point (2). If velocity of water entering at point (1) is $2\ \text{m/s}$, the velocity of water leaving at point (2) will be:

4 m/s
2 m/s
6 m/s
8 m/s✔️

Correct Answer Logic:

By continuity equation: $A_1 v_1 = A_2 v_2$. $\pi(2)^2 \times 2 = \pi(1)^2 \times v_2 \Rightarrow v_2 = \frac{4\times2}{1} = 8\ \text{m/s}$.

Mathematics QUESTION #6957

Question 5113

Evaluate: $\displaystyle\lim_{x\to1^-}\dfrac{\sqrt{\pi}-\sqrt{2\sin^{-1}x}}{\sqrt{1-x}}$

$\dfrac{1}{\sqrt{2\pi}}$
$\sqrt{\dfrac{2}{\pi}}$
$\sqrt{\dfrac{\pi}{2}}$✔️
$\sqrt{\pi}$

Correct Answer Logic:

Let $\sin^{-1}x = \pi/2-\epsilon$ where $\epsilon\to0^+$ as $x\to1^-$. Then $x=\sin(\pi/2-\epsilon)=\cos\epsilon\approx1-\epsilon^2/2$, so $1-x\approx\epsilon^2/2$.

$\sqrt{\pi}-\sqrt{2(\pi/2-\epsilon)}=\sqrt{\pi}-\sqrt{\pi-2\epsilon}=\sqrt{\pi}\left(1-\sqrt{1-\frac{2\epsilon}{\pi}}\right)\approx\sqrt{\pi}\cdot\dfrac{\epsilon}{\pi}=\dfrac{\epsilon}{\sqrt{\pi}}$

$\sqrt{1-x}\approx\sqrt{\epsilon^2/2}=\epsilon/\sqrt{2}$

Limit $=\dfrac{\epsilon/\sqrt{\pi}}{\epsilon/\sqrt{2}}=\sqrt{\dfrac{2}{\pi}}$

Correct Answer Logic:

The contrast set up by 'despite the coach's warnings' and 'oscillating wildly' signals inconsistency, matching 'erratic.'

Chemistry QUESTION #7159

Question 5115

Which of the following sequences does not accurately reflect the trend of the property mentioned?

$V^{2+} < Cr^{2+} < Mn^{2+} < Fe^{2+}$: paramagnetic behavior✔️
$Ni^{2+} < Co^{2+} < Fe^{2+} < Mn^{2+}$: ionic size
$Co^{3+} < Fe^{3+} < Cr^{3+} < Sc^{3+}$: stability in aqueous solution
$Sc < Ti < Cr < Mn$: number of oxidation states

Correct Answer Logic:

Paramagnetic behavior depends on the number of unpaired electrons.

$V^{2+}$: $[Ar] 3d^{3}$ (3 unpaired)
$Cr^{2+}$: $[Ar] 3d^{4}$ (4 unpaired)
$Mn^{2+}$: $[Ar] 3d^{5}$ (5 unpaired)
$Fe^{2+}$: $[Ar] 3d^{6}$ (4 unpaired)

Since $Fe^{2+}$ has fewer unpaired electrons than $Mn^{2+}$, the increasing order shown in Option 1 is incorrect.

Electrical Engineering QUESTION #2176

Question 5116

In a superposition problem, a $5\,\Omega$ resistor carries $1\,\text{A}$ when only $V_1$ is active, and $-0.5\,\text{A}$ when only $I_1$ is active. The actual power dissipated in the resistor when both sources act simultaneously is:

$1.25\,\text{W}$✔️
$3.125\,\text{W}$
$6.25\,\text{W}$
$1.875\,\text{W}$

Correct Answer Logic:

Superposition applies to current (not power): $I_{total} = 1 + (-0.5) = 0.5\,\text{A}$. $P = I^2 R = (0.5)^2\times5 = 1.25\,\text{W}$. Directly superimposing powers would give $1^2\times5 + 0.25\times5 = 6.25\,\text{W}$ — a common but incorrect approach.
