Economics QUESTION #1684

Disposable personal income is most accurately defined as the income that remains to households after:

Subtracting all savings from personal income
Setting aside funds exclusively for consumption expenditure
Deducting personal income taxes from personal income✔️
Excluding all government transfer payments such as social security

Correct Answer Logic:

Disposable personal income (DPI) = Personal income − Personal income taxes (direct taxes paid to the government). It represents the actual income available to households for spending (consumption) and saving. It is NOT the same as personal income (which is pre-tax) and is NOT restricted to consumption alone — households can also save their disposable income.

Question 3

A gaseous hydrocarbon produces 0.72 g of water and 3.08 g of CO$_2$ upon complete combustion. What is the empirical formula of the hydrocarbon?

$\text{C}_2\text{H}_4$
$\text{C}_3\text{H}_4$
$\text{C}_6\text{H}_5$
$\text{C}_7\text{H}_8$✔️

Correct Answer Logic:

Moles of H$_2$O $= \dfrac{0.72}{18} = 0.04\ \text{mol}$ → H atoms $= 0.08\ \text{mol}$

Moles of CO$_2 = \dfrac{3.08}{44} = 0.07\ \text{mol}$ → C atoms $= 0.07\ \text{mol}$

Ratio C : H $= 0.07 : 0.08 = 7 : 8$

Empirical formula: $\mathbf{C_7H_8}$ (like toluene)

Question 5

What is the therapeutic incompatibility of combining Tetracycline with milk?

Increased absorption
Inactivation due to chelation with Calcium✔️

Question 6

Choose the CORRECT sentence.

The news are shocking.
The news were shocking.

Question 7

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.

Dairy Food Science and Technology QUESTION #5888

Question 8

Which milk protein fraction is most responsible for heat stability of milk?

$\beta$-casein due to its hydrophobic character
$\kappa$-casein due to its surface-active glycopeptide moiety stabilizing micelles✔️
$\alpha$-lactalbumin due to its calcium-binding domain
$\beta$-lactoglobulin due to disulfide bonding

Correct Answer Logic:

$\kappa$-casein, located on the outer surface of casein micelles, provides steric and electrostatic stabilization through its negatively charged hydrophilic glycomacropeptide (GMP) tail. Its removal by chymosin or denaturation during heating ($>70^{\circ}\text{C}$) destabilizes micelles.

Physics QUESTION #1157

Question 9

The angle of incidence for which polarization is maximum is called:

Scattering angle
Angle of reflection
Polarization angle✔️
None of these

Correct Answer Logic:

The angle of incidence at which reflected light is completely polarized is called the polarization angle or Brewster's angle ($\theta_B$), given by $\tan\theta_B = n$, where $n$ is the refractive index of the denser medium.

Accounting & Finance QUESTION #9642

Question 10

A non-profit organization received subscription of Rs. 55,000 during the year. Opening subscription due = Rs. 5,000; Opening subscription received in advance = Rs. 3,000; Closing subscription due = Rs. 4,000; Closing subscription received in advance = Rs. 2,000. What is the subscription income for the year?

Rs. 55,000
Rs. 59,000
Rs. 57,000✔️
Rs. 53,000

Correct Answer Logic:

Subscription income = Cash received – Opening due – Closing advance + Closing due + Opening advance = 55,000 – 5,000 – 2,000 + 4,000 + 3,000 = Rs. 55,000. Correction: 55,000 – 5,000 + 4,000 + 3,000 – 2,000 = Rs. 55,000. The book formula: Cash received – Opening due + Closing due + Opening advance – Closing advance = 55,000 – 5,000 + 4,000 + 3,000 – 2,000 = Rs. 55,000. This equals option 1. For Rs. 57,000 the figures differ. Correct answer using the standard formula: 55,000 + 4,000 + 3,000 – 5,000 – 2,000 = 55,000. Answer is option 0 (Rs. 55,000). Note: This is a challenging scenario as students often mis-add adjustments.
