Question 1043221
30% of 40% of the men attend night school
{{{ .3*.4 = .12 }}}, so 12% of the employees 
who are men attend
night school
--------------
If 40% of the employees are men, then 60%
of the employees are women
20% of 60% of the employees attend night school
{{{ .2*.6 = .12 }}}, so 12% of the employees who are women
attend night school
{{{ .12 + .12 = .24 }}}
24% of the employees attend night school

Hope I got it!
