Answer:
17:27
Step-by-step explanation:
Blue women:yellow men = 3x:2x
Blue men:yellow women = 3y:5y
3x+3y 21
--------- = -----
2x+2y 23
x+y 7
-------- = ----
2x+5y 23
23x-14x= 35y-23y
9x=12y
x:y = 4:3
Now putting the value of x and y
Total Men = 2x+3y = 2*4+3*3 17
--------------------- ---------- ------------- = ----
Total Women = 3x+5y = 3*4+5*3 27
