Answers
the ratio of married male non-members to the married female non-members is 4 : 1
Step-by-step explanation:
Let say Total Employees = 100P
Females = (20/100)100P = 20P
Males = 100P - 20P = 80P
Male workers = 600
=> 80P = 600
=> 100P = 750
Total Employees = 750
Female = 150
Males = 600
Married Females = (40/100)150 = 60
30 Female workers not part of trade union
500 Males were members of Trade Union
=> 100 Males were not Part of Trade Union
Total Employees Not Part of trade union = 30 + 100 = 130
Married Males = (50/100) 600 = 300
The unmarried non-member male employees = 60
Married Non member Male employee = 100 - 60 = 40
The unmarried non-members of the employees were 80
=> Married non-members of the employees were = 130 - 80 = 50
Married Non member Female employee = 50 - 40 = 10
the ratio of married male non-members to the married female non-members = 40 : 10
= 4 : 1
