Answer:
A. 100(100−z)(100−y)100−z(100−y)100(100−z)(100−y)1002−z(100−y)
Step-by-step explanation:
Solution
F = yx/100 M = (100-y)x/100
Males left after retirement = ((100-z)/100)*((100-y)x/100)
=x*(100-z)(100-y)/1002
That's the total number of males
the total number of people is:
yx/100 + x*(100-z)(100-y)/1002
(100-z)(100-y)/(1002 - z(100-y))
And denominator 100y + (100-z)(100-y)
= (100)(100 – z)(100 – y) / 1002 – z(100 – y) as our answer
