Question

The mean annual salary paid to all employees in a company was 1500 Kenya pounds The mean annual salaries paid to male and female employees were 1560 Kenya pounds and 1260 Kenya pounds respectively. Determine the percentages of males and females employed by the company

Answer 1

• 80% male
• 20% female

Explanation:

Let x represent the fraction of employees that are male. Then the average salary is ...

1560x +1260(1 -x) = 1500

300x +1260 = 1500

x = 240/300 . . . . . . subtract 1260, divide by 300

x = 80%

The employees of the company are 80% male and 20% female.
