Answers
let there are 100 people working in the company
no.of men =40 and no.of women=60
since 75%men earn more than 25000,no.of men earning above 25000 are( 75/100)*40=30men but 45%of company is earning more than 25000 therefore no.of people earning more than 25000 are 45 but out of them 30 are men therefore 15 are women total no of women =60
hence fraction of women earning below 25000 are (60-15)/60=45/60=3/4
Percentage of men in a company = 40% ( given)
75% of men employee earn more than Rs.25000. ( given)
45%of company's employees earn more than Rs 25000 per year. ( given)
Let consider total number of employees = 100
According question 40% are men,
∴ men = 40
rest are women employee.
hence number of women employee = ( 100 - 40) = 60
As 75% of men earn more than 25000.
∴Total number of men ,who earn more than 25000 = 75% of 40
= × 40
=75 / 5 ×2
= 15 ×2= 30
∴ 30 men earn more than Rs.25000.
Now according the question, 45% of company's employees earn more than Rs 25000 per year,
That means 45 employees earn more than Rs.25000
Hence total female employees, who earn more than Rs.25000:-
= (45-30) = 15
∴ Number of female employees who earn less than Rs.25000 = ( 60 - 15) = 45
Hence fraction of the women employed by the company earn Rs 25000 per year or less =( 45 ÷ 60)
=
Ans :- Fraction of the women employed by the company earn Rs 25000 per year or less will be .
