For mv<pv<0 either m and p or v is -ve

1st m<p if m &p are +ve then v has to be -ve but if v is -ve then it doesnt satisfy mv<pv<0>-12 therefore it doesnt satisfy the condition mv<pv<0> o-----sufff

2nd m<0 means m is -ve with tha same logic as in 1st statment vhas to be greater than 0-----suff

Hi NYC Girl -

Could you explain Statement 1 again? where did mv<pv<0>-12 equation xome from??

"1st m<p if m &p are +ve then v has to be -ve but if v is -ve then it doesnt satisfy mv<pv<0>-12 therefore it doesnt satisfy the condition mv<pv<0> o-----sufff"

Thanks.

1 statment says M<P

now let m & p be positive eg m=2 p=4 now to satisfy mv<pv<0 V has to be negative becauz if v is postive then mv &pv both will be greater than 0 let v be -3
mv =2*-3= -6
pv = 4*-3 = -8 again this doen't satisfy mv<pv<0>-8]

therefore M& p must be ngative

let m=-4 p= -2 (m<p)
Let v=3

mv = -8 , pv=-6 [-8<-6<0] therefore mv<pv<0

V has to be greater than 0
