Free Sneak Peek

Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Analyze the relationship between **Marginal Revenue (MR), Price / Average Revenue (AR = P), and Price Elasticity of Demand (e_d)** (The **Amoroso-Robinson Formula**):

\(MR = P × e_d + 100\)

\(MR = P / e_d at all times\)

There is no mathematical relationship between them

MR = P \left( 1 - 1/e_d \right) - If **e_d > 1 (Elastic Demand)**, MR is **POSITIVE (MR > 0)** and Total Revenue rises when price drops - If **e_d = 1 (Unitary Elasticity)**, MR = 0 and Total Revenue is at its **MAXIMUM** - If **e_d < 1 (Inelastic Demand)**, MR is **NEGATIVE (MR < 0)** and Total Revenue falls when price drops

Correct Answer: Option D

Explanation:

The Amoroso-Robinson formula MR = P(1 - 1/e_d) proves that a profit-maximizing monopolist will operate exclusively in the elastic portion (e_d > 1) where MR > 0.

What is a **Sunk Cost** and why is it irrelevant for rational forward-looking\veconomic decision-making?

The cost of building a submarine that sinks in the ocean

A past historical expenditure that has **ALREADY BEEN INCURRED and CANNOT BE RECOVERED or refunded under any future decision** (e.g. customized non-resale software R&D); rational\veconomic decisions depend strictly on **Future Marginal Costs and Marginal Benefits ('Bygones are bygones')**, avoiding the **'Sunk Cost Fallacy'**

The cost of digging underground water wells

A tax penalty paid to the government

Correct Answer: Option B

Explanation:

Sunk costs are unrecoverable past outlays; rational decisions ignore sunk costs ('bygones are bygones') and focus solely on prospective marginal costs and revenues.

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Early practice in high school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, CUET, and Foundation JEE/NEET.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
