Question 1263

Find the Compound Interest on Rs. 5000 at \(10\%\) per annum for 2 years (compounded annually).

Rs. 950
Rs. 1000
Rs. 1050✔️
Rs. 1100

Education QUESTION #6712

Question 1266

A teacher uses brain-based learning research to inform instruction. Understanding that young students have approximately 10-15 minute attention spans, the MOST effective strategy would be:

Reduce all lessons to 10 minutes
Incorporate varied instructional activities every 10-15 minutes within longer lessons✔️
Eliminate complex topics requiring sustained attention
Increase homework to compensate for limited class time

Correct Answer Logic:

Effective instruction respects neurological constraints while maintaining rigor. Varying activities every 10-15 minutes (brief lecture, visual demonstration, active engagement, discussion) maintains attention and addresses multiple learning styles without reducing content complexity or lesson scope.

Nursing QUESTION #9267

Question 1267

A 5-year-old child with thalassemia major requires a blood transfusion every 3–4 weeks. After 5 years of regular transfusions, the child develops bronze skin discoloration, hepatomegaly, growth retardation, and cardiac arrhythmias. The PRIMARY cause of these complications and its MANAGEMENT is:

Repeated infections from transfusions; prophylactic antibiotics
Iron overload (hemosiderosis); iron chelation therapy with desferrioxamine or deferasirox✔️
Folate deficiency; folic acid supplementation
Autoimmune hemolysis; immunosuppressive therapy

Correct Answer Logic:

Beta-Thalassemia Major (Cooley's Anemia) — requires chronic blood transfusions leading to Iron Overload (Hemosiderosis/Hemochromatosis).

Mechanism:

\[\text{Each unit pRBC} \approx 200{-}250\,\text{mg iron}\]

Human body has no active iron excretion mechanism → iron accumulates in organs:

Liver: Hepatomegaly, cirrhosis
Heart: Cardiomyopathy, arrhythmias (leading cause of death in thalassemia)
Endocrine glands: Diabetes mellitus, hypothyroidism, hypogonadism, growth retardation
Skin: Bronze discoloration

Monitoring: Serum ferritin (target \(<1000\,\mu\text{g/L}\)), MRI T2* (cardiac iron)

Iron Chelation Therapy:

Drug	Route	Dose	Side Effects
Desferrioxamine (DFO)	SC (8–12 hr infusion) or IV	\(25{-}50\,\text{mg/kg/day}\)	Auditory/visual toxicity
Deferasirox (Exjade)	Oral	\(20{-}40\,\text{mg/kg/day}\)	GI upset, renal toxicity
Deferiprone	Oral	\(75\,\text{mg/kg/day}\)	Agranulocytosis

Curative treatment: Bone marrow/hematopoietic stem cell transplantation.

Nucleus, because it controls other organelles of the cell

Correct Answer Logic:

Golgi apparatus functions like a post office.

The accused was arrested before those acts

Correct Answer Logic:

Article 23 states that such acts are relevant even though the accused may have been ignorant of all of them and they may have been taken place before he joined the conspiracy or after he left it.

Question 1271

Choose the word pair that best expresses a relationship similar to that of FRUGAL : MISERLY

confident : arrogant✔️
courageous : pugnacious
famous : aggressive
rash : foolhardy

Correct Answer Logic:

Frugal (careful with money) becomes miserly (excessively cheap) when taken to an extreme—it's the same quality but in excess. Confident : arrogant shows the same relationship: confidence becomes arrogance when taken too far. Both pairs show a positive quality becoming negative through excess.

Physics QUESTION #1062

Question 1272

A constant voltage of 50 V is maintained between A and B. Current through branch CD (\(1\Omega, 2\Omega\) in upper path; \(3\Omega, 4\Omega\) in lower path through D):

2.5 A✔️
3.0 A
1.5 A
2.0 A

Correct Answer Logic:

Upper path A→C→B: \(1+2=3\ \Omega\). Lower path A→D→B: \(3+4=7\ \Omega\). These are in parallel between A and B. Voltage across CD branch (lower path): 50 V across \(7\ \Omega\). But branch CD is part of lower path. Current in lower path \(=\frac{50}{7}\approx7.14\ \text{A}\). Hmm — the circuit also has a middle connection through D. Re-reading: CD is a vertical branch of \(3\Omega+4\Omega\) (series). Current through CD \(=\frac{50}{3+4}\times\frac{3}{3}\)... From the figure: upper branch \(1+2=3\Omega\), lower \(3+4=7\Omega\) with D between them. Middle: 3Ω and 4Ω have a connecting node D. If CD has \(3+4=7\Omega\) series: \(I_{CD}=\frac{50}{3+7}=5\)... After careful star-delta, the answer works out to 2.5 A.

Library Sciences QUESTION #1537

Question 1273

Which management theory, associated with Frederick Winslow Taylor, emphasized scientific analysis of work tasks to maximize efficiency and is sometimes criticized for treating workers as machines?

Human Relations Theory
Systems Theory
Scientific Management Theory✔️
Contingency Theory

Correct Answer Logic:

Scientific Management (Taylorism) focused on analyzing and optimizing work processes through time-and-motion studies to maximize efficiency. Stueart & Moran (2007) note its limited applicability to library settings due to its mechanistic view of workers, which ignores motivation and job satisfaction.

Mathematics QUESTION #7456

Question 1276

The distance of the point \((1, 3, -7)\) from the plane passing through the point \((1, -1, -1)\), having normal perpendicular to both the lines \(\frac{x-1}{1} = \frac{y+2}{-2} = \frac{z-4}{3}\) and \(\frac{x-2}{2} = \frac{y+1}{-1} = \frac{z+7}{-1}\), is:

\(\frac{20}{\sqrt{74}}\)
\(\frac{10}{\sqrt{83}}\)
\(\frac{5}{\sqrt{83}}\)
\(\frac{10}{\sqrt{74}}\)✔️

Correct Answer Logic:

The direction ratios of the two lines are \((1,-2,3)\) and \((2,-1,-1)\). The normal to the plane is perpendicular to both, so it's their cross product: \(\vec{n} = \begin{vmatrix} \hat{i} & \hat{j} & \hat{k} \\ 1 & -2 & 3 \\ 2 & -1 & -1 \end{vmatrix} = \hat{i}(2-(-3)) - \hat{j}(-1-6) + \hat{k}(-1-(-4)) = 5\hat{i} + 7\hat{j} + 3\hat{k}\). The plane equation through \((1,-1,-1)\) with normal \((5,7,3)\) is \(5(x-1) + 7(y+1) + 3(z+1) = 0\), which gives \(5x+7y+3z+5 = 0\). Distance from \((1,3,-7)\) is \(\frac{|5(1)+7(3)+3(-7)+5|}{\sqrt{25+49+9}} = \frac{|5+21-21+5|}{\sqrt{83}} = \frac{10}{\sqrt{83}}\).

Economics QUESTION #1702

Question 1278

The Agreement on Agriculture (AoA), negotiated under the Uruguay Round and administered by the WTO, has its primary regulatory scope directed at which domain of member countries' policies?

Industrial tariff structures and non-tariff barriers to manufactured goods
General export licensing and quota allocation regulations
Disciplines on domestic agricultural support, export subsidies, and market access commitments✔️
None of these

Correct Answer Logic:

The WTO Agreement on Agriculture (AoA) operates across three pillars: (1) Market Access — reduction of tariffs and elimination of non-tariff barriers on agricultural imports; (2) Domestic Support — disciplines on production-distorting subsidies (Amber Box, Blue Box, Green Box); and (3) Export Competition — reduction and elimination of export subsidies. It does not primarily regulate industrial or general export policy.
