If National Income is Rs 50 crore and saving is Rs 5 crore, find out Average Propensity to Consume. When income rises to Rs 60 crore and saving to Rs 9 crore, what will be the Average Propensity to Consume and Marginal Propensity to Save?

Y = Rs 50 crore S = Rs 5 crore

Hence, C = F-S = 50-5=Rs 45 crore

Average Propensity to Consume C 45

APC = C / Y = 45 / 50 = 0.90

Again, when income and savings rise,

Y = Rs 60 crore . S=Rs 9 crore

Average Propensity to Consume (APC) = C / Y = Y-S / Y = 60-9 / 60 = 0.85

Again, ∆S = 9-5 = Rs 4 crores

∆Y = 60-50 = Rs 10 crores

Hence, Marginal Propensity to Save,

MPS = ∆S / ∆Y = 4 / 10 = 0.40
