Correct Answer - Option 4 : 8 : 15
Given:
The ratio of total salary given to male and female is 4 : 5
The wages ratio of each male and female 3 : 2
Concept:
Number of male or female = Total salary of male or female/salary of one male or female
Calculation:
Let the unit ratio of total salary be y
The total salary of male = 4y
The total salary of female = 5y
Let the unit ratio of one person salary be x
⇒ Salary of one male = 3x
⇒ Salary of one female = 2x
Number of male = Total salary of male/ Salary of one male
⇒ 4y/3x
Number of female = Total salary of female/Salary of one female
⇒ 5y/2x
Number of male/Number of female = (4y/3x)/(5y/2x)
⇒ (4y/3x) × (2x/5y)
⇒ 8 : 15
∴ The ratio of the total number of male and female 8 : 15
