यदि (MPC) अधिक हो तो दो-क्षेत्रीय चक्र में निवेश वृद्धि का आय पर प्रभाव कैसा होगा?

If (MPC) is higher what will be the effect of an investment rise on income in the two-sector flow?

Explanation opens after your attempt
Correct Answer

B. मजबूत होगाIt will be stronger

Step 1

Concept

Higher (MPC) means a larger part of extra income is spent. This strengthens the multiplier and income effect.

Step 2

Why this answer is correct

The correct answer is B. मजबूत होगा / It will be stronger. Higher (MPC) means a larger part of extra income is spent. This strengthens the multiplier and income effect.

Step 3

Exam Tip

अधिक (MPC) से अतिरिक्त आय का बड़ा भाग खर्च होता है। इससे गुणक और आय प्रभाव मजबूत होता है।

यदि निवेश में (20) की वृद्धि और (MPC=0.5) हो तो आय में संभावित वृद्धि कितनी होगी?

If investment rises by (20) and (MPC=0.5) what will be the possible rise in income?

Explanation opens after your attempt
Correct Answer

C. (40)

Step 1

Concept

Here \(k=\frac{1}{1-0.5}=2\). Income rise will be \(20\times2=40\).

Step 2

Why this answer is correct

The correct answer is C. (40). Here \(k=\frac{1}{1-0.5}=2\). Income rise will be \(20\times2=40\).

Step 3

Exam Tip

यहां \(k=\frac{1}{1-0.5}=2\) है। आय वृद्धि \(20\times2=40\) होगी।

यदि निवेश (10) घटे और (MPC=0.8) हो तो आय पर अनुमानित प्रभाव क्या होगा?

If investment falls by (10) and (MPC=0.8) what will be the estimated effect on income?

Explanation opens after your attempt
Correct Answer

A. (50) की कमीDecrease by (50)

Step 1

Concept

At (MPC=0.8) the multiplier is (5). A fall of (10) in investment can reduce income by (50).

Step 2

Why this answer is correct

The correct answer is A. (50) की कमी / Decrease by (50). At (MPC=0.8) the multiplier is (5). A fall of (10) in investment can reduce income by (50).

Step 3

Exam Tip

(MPC=0.8) पर गुणक (5) है। निवेश में (10) की कमी से आय (50) घट सकती है।

दो-क्षेत्रीय मॉडल में (S=I) को केवल लेखांकन समानता नहीं बल्कि संतुलन शर्त क्यों माना जाता है?

Why is (S=I) treated not only as an accounting equality but also as an equilibrium condition in the two-sector model?

Explanation opens after your attempt
Correct Answer

B. क्योंकि यह नियोजित रिसाव और नियोजित इंजेक्शन को बराबर करता हैBecause it equates planned leakage and planned injection

Step 1

Concept

When planned saving and investment are equal demand in the income flow can remain stable. Pay attention to the word planned in exams.

Step 2

Why this answer is correct

The correct answer is B. क्योंकि यह नियोजित रिसाव और नियोजित इंजेक्शन को बराबर करता है / Because it equates planned leakage and planned injection. When planned saving and investment are equal demand in the income flow can remain stable. Pay attention to the word planned in exams.

Step 3

Exam Tip

नियोजित बचत और निवेश बराबर हों तो आय चक्र में मांग स्थिर रह सकती है। परीक्षा में नियोजित शब्द पर ध्यान दें।

यदि वास्तविक निवेश में अनियोजित स्टॉक वृद्धि शामिल है तो किस बात का संकेत मिलता है?

If actual investment includes unplanned inventory accumulation what does it indicate?

Explanation opens after your attempt
Correct Answer

A. उत्पाद मांग अपेक्षा से कम रहीProduct demand was lower than expected

Step 1

Concept

Unplanned inventory accumulation means goods did not sell as expected. It shows deficient demand.

Step 2

Why this answer is correct

The correct answer is A. उत्पाद मांग अपेक्षा से कम रही / Product demand was lower than expected. Unplanned inventory accumulation means goods did not sell as expected. It shows deficient demand.

Step 3

Exam Tip

अनियोजित स्टॉक वृद्धि का अर्थ है कि वस्तुएं अपेक्षा के अनुसार नहीं बिकीं। यह मांग की कमी दर्शाती है।

यदि वास्तविक निवेश में अनियोजित स्टॉक कमी दिखाई दे तो क्या संकेत होगा?

If actual investment shows unplanned inventory depletion what will it indicate?

Explanation opens after your attempt
Correct Answer

B. मांग अपेक्षा से अधिक थीDemand was higher than expected

Step 1

Concept

Inventory depletion shows that sales exceeded expectations. Firms may increase output later.

Step 2

Why this answer is correct

The correct answer is B. मांग अपेक्षा से अधिक थी / Demand was higher than expected. Inventory depletion shows that sales exceeded expectations. Firms may increase output later.

Step 3

Exam Tip

स्टॉक कमी बताती है कि बिक्री अपेक्षा से अधिक हो गई। फर्म आगे उत्पादन बढ़ा सकती हैं।

दो-क्षेत्रीय मॉडल में यदि (C=100+0.8Y) और (I=50) है तो संतुलन आय क्या होगी?

In the two-sector model if (C=100+0.8Y) and (I=50) what will be equilibrium income?

Explanation opens after your attempt
Correct Answer

B. (750)

Step 1

Concept

In equilibrium (Y=C+I) so (Y=100+0.8Y+50). Thus (0.2Y=150) and (Y=750).

Step 2

Why this answer is correct

The correct answer is B. (750). In equilibrium (Y=C+I) so (Y=100+0.8Y+50). Thus (0.2Y=150) and (Y=750).

Step 3

Exam Tip

संतुलन में (Y=C+I) होगा इसलिए (Y=100+0.8Y+50)। इससे (0.2Y=150) और (Y=750) होगा।

यदि (C=50+0.5Y) और (I=100) हो तो दो-क्षेत्रीय संतुलन आय कितनी होगी?

If (C=50+0.5Y) and (I=100) what will be the two-sector equilibrium income?

Explanation opens after your attempt
Correct Answer

C. (300)

Step 1

Concept

In equilibrium (Y=50+0.5Y+100). Therefore (0.5Y=150) and (Y=300).

Step 2

Why this answer is correct

The correct answer is C. (300). In equilibrium (Y=50+0.5Y+100). Therefore (0.5Y=150) and (Y=300).

Step 3

Exam Tip

संतुलन में (Y=50+0.5Y+100) है। इसलिए (0.5Y=150) और (Y=300) होगा।

यदि (C=40+0.6Y) और (I=80) है तो संतुलन आय क्या होगी?

If (C=40+0.6Y) and (I=80) what is equilibrium income?

Explanation opens after your attempt
Correct Answer

D. (300)

Step 1

Concept

In equilibrium (Y=40+0.6Y+80). Therefore (0.4Y=120) and (Y=300).

Step 2

Why this answer is correct

The correct answer is D. (300). In equilibrium (Y=40+0.6Y+80). Therefore (0.4Y=120) and (Y=300).

Step 3

Exam Tip

संतुलन में (Y=40+0.6Y+80) होगा। इसलिए (0.4Y=120) और (Y=300) है।

दो-क्षेत्रीय मॉडल में (C=20+0.75Y) होने पर बचत फलन कौन सा होगा?

In the two-sector model if (C=20+0.75Y) what will be the saving function?

Explanation opens after your attempt
Correct Answer

A. (S=-20+0.25Y)

Step 1

Concept

Saving is (S=Y-C). Therefore (S=Y-\left\(20+0.75Y\right\)=-20+0.25Y).

Step 2

Why this answer is correct

The correct answer is A. (S=-20+0.25Y). Saving is (S=Y-C). Therefore (S=Y-\left\(20+0.75Y\right\)=-20+0.25Y).

Step 3

Exam Tip

बचत (S=Y-C) होती है। इसलिए (S=Y-\left\(20+0.75Y\right\)=-20+0.25Y) होगा।
