Question 2

Under Section 22(2), where no provision for appeal or review exists under the rules, a civil servant aggrieved by any order may make a representation to the authority next above the authority which made the order. However, no representation shall lie on matters relating to what?

Determination of pay or allowances
Determination of fitness to hold a particular post or to be promoted to a higher post or grade✔️
Disciplinary action taken against the civil servant
Transfer orders issued by the appointing authority

Correct Answer Logic:

The proviso to Section 22(2) explicitly bars representations on matters relating to the determination of fitness of a person to hold a particular post or to be promoted to a higher post or grade. Fitness determinations are matters of discretion reserved for the competent authority and are not subject to representational challenge.

Electrical Engineering QUESTION #2162

Question 4

A 220 kV transmission line has surge impedance $Z_c = 250\,\Omega$. The Surge Impedance Loading (SIL) is:

$193.6\,\text{MW}$✔️
$96.8\,\text{MW}$
$387.2\,\text{MW}$
$484\,\text{MW}$

Correct Answer Logic:

$\text{SIL} = \frac{V_R^2}{Z_c} = \frac{(220 \times 10^3)^2}{250} = \frac{4.84 \times 10^{10}}{250} = 193.6\,\text{MW}$.

Biology QUESTION #7288

Question 5

The common nitrogen-fixer in paddy fields is:

Frankia
Rhizobium
Azospirillum
Oscillatoria✔️

Correct Answer Logic:

Oscillatoria is a filamentous cyanobacterium that fixes atmospheric nitrogen in paddy (rice) fields and is widely used as a biofertiliser. Other cyanobacteria like Anabaena and Nostoc also fix nitrogen in paddy fields. Rhizobium is specific to legumes; Frankia to non-leguminous trees; Azospirillum is a free-living aerobic fixer associated with grasses.

Nursing QUESTION #9276

Question 6

A child with Type 1 Diabetes Mellitus presents with: blood glucose 28 mmol/L, pH 7.14, bicarbonate 10 mEq/L, positive ketones in urine. The child is drowsy. This presentation is BEST described as and the INITIAL fluid management priority is:

Hyperosmolar hyperglycemic state; rapid IV insulin bolus
Diabetic Ketoacidosis (DKA); IV fluid resuscitation with 0.9% NaCl 10–20 mL/kg over 1–2 hours✔️
Hypoglycemia with rebound hyperglycemia; 10% dextrose
Lactic acidosis; sodium bicarbonate infusion

Correct Answer Logic:

Diabetic Ketoacidosis (DKA) — Diagnostic criteria in children:

Blood glucose $>11\,\text{mmol/L}$ (or known DM)
pH $<7.3$ or bicarbonate $<15\,\text{mEq/L}$
Ketonemia/ketonuria

Severity classification:

Severity	pH	HCO₃
Mild	7.20–7.29	10–15
Moderate	7.10–7.19	5–9
Severe	<7.10	<5

This child: pH 7.14, HCO₃ 10 = Moderate-Severe DKA

Management (ISPAD/BSPED guidelines):

Fluid resuscitation FIRST (not insulin first): $10{-}20\,\text{mL/kg}$ of 0.9% NaCl over 1–2 hours if shocked
Replace fluid deficit over 24–48 hours with 0.9% NaCl
Start insulin infusion: $0.05{-}0.1\,\text{units/kg/hr}$ IV (NEVER bolus in children — risk of cerebral edema)
Add dextrose to IV fluid when BG $\leq 14\,\text{mmol/L}$
Monitor for cerebral edema (most feared complication — headache, bradycardia, $\downarrow$ consciousness)

Bicarbonate is NOT recommended in pediatric DKA — worsens cerebral edema.

Verbal Reasoning QUESTION #8103

Question 9

Compare the two quantities below.

Column A: $(0.82)^2 \cdot (0.82)^3$

Column B: $(0.82)^6$

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:

Using the rule of exponents: $(0.82)^2 \cdot (0.82)^3 = (0.82)^{2+3} = (0.82)^5$.

Now compare $(0.82)^5$ vs $(0.82)^6$.

Since $0 < 0.82 < 1$, multiplying by $0.82$ makes the number smaller. Therefore $(0.82)^5 > (0.82)^6$.

Column A is greater.

Civil Engineering QUESTION #6575

Question 10

The specific energy in open channel flow is given by:

\$ E = y - \\dfrac{\\alpha V^2}{2g} \$
\$ E = y - \\dfrac{V^2}{2g\\alpha} \$
\$ E = y + \\dfrac{V^2}{2g\\alpha} \$
\$ E = y + \\dfrac{\\alpha V^2}{2g} \$✔️

Correct Answer Logic:

Specific energy is defined as energy per unit weight measured relative to the channel bed: $E = y + \dfrac{\alpha V^2}{2g}$, where $y$ = flow depth, $V$ = mean velocity, $\alpha$ = kinetic energy correction factor, $g$ = gravitational acceleration.

Contracts QUESTION #5864

Question 11

A Seller ships goods 'C.O.D.' (Collect on Delivery). Does the Buyer have a right to inspect before paying?

Yes, the right to inspect is absolute.
No, C.O.D. terms generally exclude the right to inspect before payment.✔️
Yes, but only for visible defects.
No, unless the Buyer is a non-merchant.

Correct Answer Logic:

Under UCC §2-513(3), the buyer is not entitled to inspect the goods before payment when the contract provides for payment on delivery (C.O.D.).

Chemistry QUESTION #7410

Question 15

Which of the following lanthanoid ions is diamagnetic? (Atomic numbers: Ce = 58, Sm = 62, Yb = 70)

$\text{Yb}^{2+}$✔️
$\text{Ce}^{2+}$
$\text{Sm}^{2+}$
$\text{Eu}^{2+}$

Correct Answer Logic:

Diamagnetic means all electrons are paired (no unpaired electrons).

$\text{Yb}^{2+}$: Yb (Z=70) = [Xe] 4f¹⁴ 6s². Yb²⁺ = [Xe] 4f¹⁴ → completely filled f subshell → all electrons paired → diamagnetic ✓

Ce²⁺ = [Xe]4f², Sm²⁺ = [Xe]4f⁶, Eu²⁺ = [Xe]4f⁷ — all have unpaired f-electrons and are paramagnetic.

Chemistry QUESTION #4361

Question 18

Which one of the following has higher vapour pressure?

Acetone
Acetaldehyde
Isopentane✔️
Benzene

Correct Answer Logic:

Vapour pressure depends on intermolecular forces — weaker forces mean higher vapour pressure. Isopentane ($C_5H_{12}$) has only weak London dispersion forces (low boiling point: $28°C$), giving it the highest vapour pressure among the options.

Physics QUESTION #1032

Question 20

In some units, time $t$ and position $x$ of a particle satisfy $t = x^2 + x$. The acceleration of the particle is:

$+\dfrac{2}{(x+1)^3}$
$+\dfrac{2}{2x+1}$
$-\dfrac{2}{(x+2)^3}$
$-\dfrac{2}{(2x+1)^3}$✔️

Correct Answer Logic:

$\frac{dt}{dx} = 2x+1\Rightarrow v = \frac{dx}{dt} = \frac{1}{2x+1}$. Acceleration: $a = \frac{dv}{dt} = \frac{dv}{dx}\cdot v = \frac{-2}{(2x+1)^2}\cdot\frac{1}{2x+1} = \frac{-2}{(2x+1)^3}$.
