यदि (S=25) और (I=40) है तो आय चक्र में कौन सा संकेत अधिक सही है?

If (S=25) and (I=40) which signal is more correct in the income flow?

Explanation opens after your attempt
Correct Answer

B. इंजेक्शन अधिक हैInjection is higher

Step 1

Concept

Investment is greater than saving so injection is higher. This can create expansionary pressure on income and output.

Step 2

Why this answer is correct

The correct answer is B. इंजेक्शन अधिक है / Injection is higher. Investment is greater than saving so injection is higher. This can create expansionary pressure on income and output.

Step 3

Exam Tip

निवेश बचत से अधिक है इसलिए इंजेक्शन अधिक है। इससे आय और उत्पादन में विस्तार का दबाव बन सकता है।

दो-क्षेत्रीय मॉडल में (MPC) घटने पर समान निवेश वृद्धि का आय प्रभाव क्यों कम होगा?

Why will the income effect of the same investment rise be smaller when (MPC) falls in the two-sector model?

Explanation opens after your attempt
Correct Answer

A. क्योंकि बचत रिसाव बढ़ जाता हैBecause saving leakage rises

Step 1

Concept

Lower (MPC) means higher (MPS). Higher saving weakens the chain of further spending.

Step 2

Why this answer is correct

The correct answer is A. क्योंकि बचत रिसाव बढ़ जाता है / Because saving leakage rises. Lower (MPC) means higher (MPS). Higher saving weakens the chain of further spending.

Step 3

Exam Tip

कम (MPC) का अर्थ अधिक (MPS) होता है। अधिक बचत आगे के खर्च की श्रृंखला को कमजोर करती है।

यदि (MPS=0.2) है तो (MPC) और गुणक क्रमशः क्या होंगे?

If (MPS=0.2) what will (MPC) and multiplier respectively be?

Explanation opens after your attempt
Correct Answer

B. (0.8) और (5)(0.8) and (5)

Step 1

Concept

(MPC=1-MPS=0.8) and \(k=\frac{1}{MPS}=5\). Remember the formulas by linking them with leakage.

Step 2

Why this answer is correct

The correct answer is B. (0.8) और (5) / (0.8) and (5). (MPC=1-MPS=0.8) and \(k=\frac{1}{MPS}=5\). Remember the formulas by linking them with leakage.

Step 3

Exam Tip

(MPC=1-MPS=0.8) और \(k=\frac{1}{MPS}=5\) है। सूत्रों को रिसाव से जोड़कर याद रखें।

यदि (MPS=0.5) है और निवेश (30) बढ़ता है तो आय में परिवर्तन कितना होगा?

If (MPS=0.5) and investment rises by (30) what will be the change in income?

Explanation opens after your attempt
Correct Answer

C. (60)

Step 1

Concept

The multiplier is \(k=\frac{1}{MPS}=2\). Therefore change in income will be \(30\times2=60\).

Step 2

Why this answer is correct

The correct answer is C. (60). The multiplier is \(k=\frac{1}{MPS}=2\). Therefore change in income will be \(30\times2=60\).

Step 3

Exam Tip

गुणक \(k=\frac{1}{MPS}=2\) है। इसलिए आय में परिवर्तन \(30\times2=60\) होगा।

यदि (C=25+0.5Y) और (I=75) है तो संतुलन आय कितनी होगी?

If (C=25+0.5Y) and (I=75) what will be equilibrium income?

Explanation opens after your attempt
Correct Answer

D. (200)

Step 1

Concept

In equilibrium (Y=25+0.5Y+75). Therefore (0.5Y=100) and (Y=200).

Step 2

Why this answer is correct

The correct answer is D. (200). In equilibrium (Y=25+0.5Y+75). Therefore (0.5Y=100) and (Y=200).

Step 3

Exam Tip

संतुलन में (Y=25+0.5Y+75) है। इसलिए (0.5Y=100) और (Y=200) होगा।

यदि (C=70+0.7Y) और (I=50) हो तो संतुलन आय क्या होगी?

If (C=70+0.7Y) and (I=50) what will be equilibrium income?

Explanation opens after your attempt
Correct Answer

A. (400)

Step 1

Concept

In equilibrium (Y=70+0.7Y+50). Therefore (0.3Y=120) and (Y=400).

Step 2

Why this answer is correct

The correct answer is A. (400). In equilibrium (Y=70+0.7Y+50). Therefore (0.3Y=120) and (Y=400).

Step 3

Exam Tip

संतुलन में (Y=70+0.7Y+50) होगा। इसलिए (0.3Y=120) और (Y=400) है।

यदि (C=10+0.9Y) और (I=40) है तो संतुलन आय कितनी होगी?

If (C=10+0.9Y) and (I=40) what will be equilibrium income?

Explanation opens after your attempt
Correct Answer

C. (500)

Step 1

Concept

In equilibrium (Y=10+0.9Y+40). Therefore (0.1Y=50) and (Y=500).

Step 2

Why this answer is correct

The correct answer is C. (500). In equilibrium (Y=10+0.9Y+40). Therefore (0.1Y=50) and (Y=500).

Step 3

Exam Tip

संतुलन में (Y=10+0.9Y+40) है। इसलिए (0.1Y=50) और (Y=500) होगा।

यदि (C=90+0.6Y) हो तो ब्रेक ईवन आय कितनी होगी?

If (C=90+0.6Y) what will be the break even income?

Explanation opens after your attempt
Correct Answer

B. (225)

Step 1

Concept

At break even (Y=C). From (Y=90+0.6Y), (0.4Y=90) and (Y=225).

Step 2

Why this answer is correct

The correct answer is B. (225). At break even (Y=C). From (Y=90+0.6Y), (0.4Y=90) and (Y=225).

Step 3

Exam Tip

ब्रेक ईवन पर (Y=C) होता है। (Y=90+0.6Y) से (0.4Y=90) और (Y=225) है।

यदि (Y=600), (C=520) और (I=80) है तो दो-क्षेत्रीय मॉडल में स्थिति क्या है?

If (Y=600), (C=520) and (I=80) what is the situation in the two-sector model?

Explanation opens after your attempt
Correct Answer

C. (S=I) है(S=I)

Step 1

Concept

Saving is (600-520=80) and investment is also (80). Therefore leakage and injection are equal.

Step 2

Why this answer is correct

The correct answer is C. (S=I) है / (S=I). Saving is (600-520=80) and investment is also (80). Therefore leakage and injection are equal.

Step 3

Exam Tip

बचत (600-520=80) है और निवेश भी (80) है। इसलिए रिसाव और इंजेक्शन बराबर हैं।

यदि (Y=300), (C=260) और (I=55) है तो सही निष्कर्ष क्या होगा?

If (Y=300), (C=260) and (I=55) what will be the correct conclusion?

Explanation opens after your attempt
Correct Answer

B. (S<I) इसलिए इंजेक्शन अधिक है(S<I) so injection is higher

Step 1

Concept

Saving is (40) while investment is (55). Therefore investment is higher and injection is greater.

Step 2

Why this answer is correct

The correct answer is B. (S<I) इसलिए इंजेक्शन अधिक है / (S<I) so injection is higher. Saving is (40) while investment is (55). Therefore investment is higher and injection is greater.

Step 3

Exam Tip

बचत (40) है जबकि निवेश (55) है। इसलिए निवेश अधिक है और इंजेक्शन अधिक माना जाएगा।
