- question was something like this. anybody know the ans?
Read Solution (Total 4)
-
- Let W- Total no. of women, T- total people
Eqn will be,
m(T-W)/100 +w*W/100 =tT/100
solve this
W= (m-t)*T/(w+m) - 11 years agoHelpfull: Yes(10) No(4)
- let F=total no of women, T= total people
(T-F)*m + F*w=T*t
=> F=T*(t-m)/(w-m) - 9 years agoHelpfull: Yes(10) No(0)
- m(T-W)/100 -w*W/100 =tT/100
solve this
W= (m-t)/(w+m)
W- women no., T- total people , - 11 years agoHelpfull: Yes(6) No(6)
- Total People= X Women= a Men=X-a
Total White= t(X)/100 {t% white} Total Black= t(X-a)/100
m(X-a)/100 {m %of men white} wa/100 {w %of Women white}
m(X-a)/100 + wa/100 =t(X)/100 a=(tX-mX+ma)/w; Ans may be. - 11 years agoHelpfull: Yes(0) No(0)
