Please Solve this question..

Dear Student,
 

Income(Y) (Rs.)	Consumption Expenditure(C) (Rs.)	Marginal Propensity to Save (ΔS/ΔY) (Rs.)	Average Propensity to Save (S/Y) (Rs.)	Savings(S) (Rs.)	Marginal Propensity to Consume (ΔC/ΔY) (Rs.)
0	80	_	_	-80	_
100	140	0.4	-0.4	-40	0.6
200	200	0.4	0	0	0.6
300	240	0.6	0.2	60	0.4
400	260	0.8	0.35	140	0.2

Formulae Used:
Savings = Income - Consumption
Marginal propensity to save = ΔS/ΔY, where ΔS is the Change in savings and ΔY is the change in income in the economy.
Marginal propensity to consume = ΔC/ΔY, where ΔC is the Change in consumption and ΔY is the change in income in the economy.
Average propensity to save = Savings / Income
MPC+MPS=1
