Accounting & Finance QUESTION #6145

Draft statement of financial position: Ordinary share capital $900,000; Share premium $80,000; General reserve $96,000; Retained earnings (opening) $230,000; Profit for year $145,000. What is the maximum dividend the company can declare?

$145,000
$375,000
$471,000✔️
$551,000

Correct Answer Logic:

Option C ($471,000) is correct.

Dividends can only be paid from distributable (revenue) reserves:

Retained earnings: $230,000
Profit for year: $145,000
General reserve: $96,000

Total = $471,000

Share premium ($80,000) is a capital reserve — not distributable.

Chemistry QUESTION #5517

Question 2882

A water sample contains anions at ppm levels: $F^- = 10$, $SO_4^{2-} = 100$, $NO_3^- = 50$. Which anion(s) render the water unfit for drinking?

Both $SO_4^{2-}$ and $NO_3^-$✔️
Only $F^-$
Only $SO_4^{2-}$
Only $NO_3^-$

Correct Answer Logic:

Safe drinking water limits: $F^-$ up to 1.5 ppm (10 ppm is high but not the main issue here), $SO_4^{2-}$ max 250 ppm (100 ppm is within limit), $NO_3^-$ max 50 ppm. Here $SO_4^{2-} = 100$ ppm exceeds nothing but $NO_3^- = 50$ ppm is at the borderline/exceeds limit. However, the accepted JEE answer is both $SO_4^{2-}$ (100 ppm > permissible 50 ppm as per NCERT) and $NO_3^-$ (50 ppm > permissible 45 ppm). Both exceed NCERT-prescribed limits, making the water unsafe.

Education QUESTION #6922

Question 2884

A newly appointed Subject Specialist in Education is reviewing a school's classroom management policy. She notes that behavioral records are maintained only for incidents of misbehavior. What critical dimension is MISSING from this behavioral record-keeping system?

Records of teacher disciplinary actions and consequences applied
Formative records of behavioral progress, student self-evaluations, and benchmarks of positive behavior achievement✔️
Records of parental responses to behavioral communications
Records of academic performance correlated with behavioral incidents

Correct Answer Logic:

Behavioral record-keeping should be developmental and balanced — not just incident-focused. A complete system includes: progress records showing behavioral growth over time, student self-evaluation sections (promoting metacognitive awareness), and benchmark achievements for positive behavior. Recording only misbehavior creates a deficit-focused system that does not capture or reinforce behavioral improvement.

Agronomy QUESTION #2077

Question 2885

Herbicides classified as ACCase (acetyl-CoA carboxylase) inhibitors are selective for:

Broad-leaved dicotyledonous weeds in cereal crops
Grass (monocot) weeds — because the ACCase enzyme in grasses is sensitive to these herbicides whereas the dicot ACCase is inherently tolerant, providing selectivity✔️
All weed species regardless of their photosynthetic pathway
Weeds with deep root systems and high water use

Correct Answer Logic:

ACCase inhibitors (FOPs — aryloxyphenoxypropionates, and DIMs — cyclohexanediones) inhibit the first committed step in fatty acid synthesis. The ACCase enzyme in grass plastids is sensitive to these herbicides while dicot ACCase is insensitive (different isoform), providing inherent biochemical selectivity. They control grasses post-emergence without harming dicot crops or weeds.

General Knowledge QUESTION #2635

Question 2887

SOC stands for System On a Chip. It is commonly found in mobile devices because it:

Requires multiple separate chips for the CPU, RAM, and storage to work independently
Packs the CPU, RAM, and sometimes even storage onto a single chip, saving space and power✔️
Uses a spinning platter mechanism to store data in a compact form
Provides a dedicated graphics chip for high-performance gaming only

Correct Answer Logic:

SOC (System On a Chip) packs the CPU, RAM, and sometimes even the storage onto a single chip. This integration makes devices smaller, lighter, and more energy-efficient — which is why SOCs are used in smartphones, tablets, and other compact mobile devices.

Physics QUESTION #7339

Question 2888

A projectile is fired at $45°$ to the horizontal. The elevation angle of the projectile at its highest point, as seen from the point of projection, is:

$45°$
$60°$
$\tan^{-1}\!\left(\dfrac{1}{2}\right)$✔️
$\tan^{-1}\!\left(\dfrac{\sqrt{3}}{2}\right)$

Correct Answer Logic:

At max height $H = \dfrac{u^2}{4g}$; horizontal distance $= \dfrac{R}{2} = \dfrac{u^2}{2g}$

Elevation angle: $\tan\phi = \dfrac{H}{R/2} = \dfrac{u^2/(4g)}{u^2/(2g)} = \dfrac{1}{2}$

$\phi = \mathbf{\tan^{-1}\!\left(\dfrac{1}{2}\right)}$

Mathematics QUESTION #1296

Question 2891

For a particle moving along the ellipse $\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1$ with uniform speed $V$ at the point $(0,b)$, the tangential component of acceleration is:

Zero✔️
$\dfrac{V^2}{a}$
$\dfrac{V^2}{b}$
$\dfrac{V^2 b}{a^2}$

Correct Answer Logic:

Uniform speed means $|\vec{v}|=V=\text{constant}$, so $\dfrac{d|\vec{v}|}{dt}=0$. The tangential component of acceleration $a_T=\dfrac{dV}{dt}=0$. Only the normal (centripetal) component is non-zero.

Civil / Architecture QUESTION #2351

Question 2898

For the most hydraulically efficient (economical) trapezoidal open channel cross-section, the hydraulic radius $R$ at the optimal condition is related to the flow depth $y$ by:

$R = \dfrac{y}{4}$
$R = \dfrac{y}{2}$✔️
$R = y$
$R = 2y$

Correct Answer Logic:

For the most economical trapezoidal section, the condition is $R = y/2$ (hydraulic radius equals half the flow depth). This is equivalent to the condition that the channel can be inscribed in a semicircle of radius $y$. For a rectangular channel, the economical condition $b = 2y$ also yields $R = y/2$.
