Question:

If Marginal propensity to consume (MPC) is 4 times of the value of the Marginal propensity to save (MPS) determine the value of MPC :

Options:

0.70

0.75

0.20

0.80

Correct Answer:

0.80

Explanation:

The correct answer is option (4) : 0.40

If the Marginal Propensity to Consume )MOC) is 4 times the value of the Marginal Propensity to save (MPS), we can represents this relationship with the equation :

MPC = 4 * MPS

If we assume MPS to be "x," then :

MPC = 4 * x

MPC + MPS = 1

4 * MPS + MPS = 1

Now, combine like terms :

5 * MPS = 1

Now, solve for MPS :

MPS = $\frac{1}{5}$

So, the value of MPS is $\frac{1}{5}$. Now, we can find the value of MPC :

MPC = 4 * MPS

MPC = 4* ($\frac{1}{5}$)

MPC = $\frac{4}{5}$

Therefore, the value of MPC is $\frac{4}{5}$, which is equivalent to 0.80.
