APS becomes zero when savings are zero. Savings are calculated as:
\[ {Savings} = {Income} - {Consumption}. \]
From the table: At an income of rupees100, consumption is also rupees 100, resulting in zero savings. Therefore, APS becomes zero at rupees 100.
| Income (Y) (in ₹ crore) | Savings (in ₹ crore) | Consumption (in ₹ crore) | Average Propensity to Consume (APC) |
|---|---|---|---|
| 0 | (i) | 30 | - |
| 100 | 0 | 30 | 1 |
| 200 | 30 | 170 | 0.85 |
| 300 | 60 | 240 | 0.8 |
Find the Derivative \( \frac{dy}{dx} \)
Given:\[ y = \cos(x^2) + \cos(2x) + \cos^2(x^2) + \cos(x^x) \]
