Re: OG 12-CR Problem
As the 1st line states that %of households with 40k or more as annual income in M county is greater than S county.. |
let,no of households with 40k r more income in M county=a
total no of households in M county =b
no of households with 40k or more income in S county = c
total no of households in S county = d
therfore,a/b > c/d
which doesnt necessarily implies that a>c,it may be or may not be depending on values of b and c...
