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 |
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

Explanation
-
We need to calculate Savings
Income = Savings + Consumption
Savings = Income - Consumption
-
APC = Consumption/ Income
- APS = Savings/ Income
