1. The value added is 20000-16000 = 4000. Also by income method, labor income= 4000. hence option C is correct.
2. As real GDP has increased, meaning more is produced. Had prices remain same as that of base year, the nominal GDP would still increase. In fact prices fell, which is why nominal gdp is same. The increase in output is offset by decrease in price. option B is correct.
3. Option A is correct. This is called the quality adjustment bias. A improved quality good is valued more. Inflation does not takes this into account and accounts the increase in price to overall price level change.
4. Participation rate = 0.65 = unemployed+employed/employable population
0.65 = labor force/250million
labor force = 162.5million
unemployment rate = unemployed/labor force
0.05 = unemployed/162.5million
unemployed= 8.125million
employed= 162.5-8.125 = 154.375million = 154.4million. Correct option is A.
