Rishika singh  (9 years ago)

let total no. of male is M and female is F
so sum of all males= 52M
sum of all females=42F
mean age of all employee is 50, means its the average age of all male and female
sum of males+sum of females=50(M+F)
52M+42F=50M+50F
BY solving we get,
M=4F
using this % of male and female employee=80 and 20
