Question 199852
in a certain company, 30 percent of men and 20 percent of women attend night school.
If 40 percent of all employees are men, what % of ALL employees attend night school?
:
Let t = total no. of employees
then
.4t = men
and
.6t = women
:
Let x = per cent of all employees
:
% men + % women = % total go to night school
.3(.4t) + .2(.6t) = xt
:
.12t + .12t = xt
:
.24t = xt
Divide equation by t
.24 = x
:
24% go to night school
