How many people are unemployed if the employment ratio is 75%, there are 90 million people
employed, and there are 20 million people not in the labor force?

A. 0 million

B. 5 million

C. 10 million

D. 20 million

C. 10 million

Step-by-step explanation

In order to find the number of unemployed people, we first need to identify the total population:

Employment ratio = no. employed people / total population 

Given in the problem that the employment ratio is 75% and the people employed at 90 million thus 

75% = 90,000,000 / total population

total population = 90,000,000 / 75% or 

TP = 90,000,000 / .75

Total Population = 120,000,000

Total population = number of employed + employed + people not in labor force

120,000,000 = 90,000,000 + no. of unemployed + 20,000,000

120,000,000 = 110,000,000 = number of unemployed 

unemployed = 120,000,000 - 110,000,000

number of unemployed = 10,000,000

Hence the number of unemployed people in based on the given scenario is 10,000,000 or 10 million
