For Solving the Questions, we need to Remember following formulas

Income = Consumption + Savings

Y = C + S

APC = Consumption/ Income

APC = C/Y

APS = Savings/ Income

APS = C/Y

Example 1 

Calculate APC and APS from the following schedule.

       
Income (Y) 100 200 300
Consumption (C) 80 120 180

View answer

In this question, we are given Income(Y) and Consumption (C)

We need to first calculate Savings ( S) using formula

Income = Consumption + Savings

Y = C + S

Y - C = S

S = Y - C

 

Then we can calculate APC And APS Easily

APC = Consumption/ Income

APC = C/Y

 

APS = Savings/ Income

APS = C/Y

Income Consumption Savings APC APS
100 80 20 0.8 0.2
200 120 80 0.6 0.4
300 180 120 0.6 0.4

Note

Sometimes in Question

Disposable income is mentioned

Note that

Disposable income and Income (Y) are same things

Example 3

(i) The disposable income (Y) is ₹ 1200 crores and consumption expenditure (C) is ₹ 800 crores. Calculate the APC.

(ii) If saving is ₹ 500, out of an income of ₹ 5,000, how much is the APS?

(iii) If disposable income is ₹ 1,000 and consumption expenditure is ₹ 750, find out average propensity to save.

(iv) If income is ₹ 500 and saving are ₹ 100, calculate APC.

(v) When income rises from ₹ 1,000 to ₹ 1,100, saving rise by ₹ 30. Find out MPS and MPC.

 

(i) Disposable Income (Y) = 1200

    Consumption expenditure (C) = 800

    Calculate APC

 

(ii) Savings = 500

     Income = 5000

     Find APS

 

(iii) Disposable Income (Y) = 1000

      Consumption expenditure (C) = 750

      Find APS

 

(iv) Income = 500

      Savings = 100

      Calculate APC

 

View answer

(i) APC = C/Y

    APC = 800/1200

    APC = 2/3

    APC = 0.67

 

(ii) APS = S/Y

     APS = 500/5000

     APS = 1/10

     APS = 0.1

 

(iii) APC = C/Y = 750/1000

     APC = 0.75

 

APS + APC = 1

APS + 0.75 = 1

APS = 0.25

 

(iv) APS = S/Y = 100/500

      APS = 0.2

 

APS + APC = 1

0.2 + APC = 1

APC = 0.8
