Answer:
The unemployment rate refers to the rate, which may be denoted in terms of the percentage of the workers who are unemployed within a total labor force.
Explanation:
Unemployment rate = (unemployed / Labor force) * 100
= (10,00,000 / (90,00,000 + 10,00,000)) * 100
= (10,00,000 / 1,00,00,000) * 100
= 10%
Therefore, the unemployment rate is 10%
