Is 1/p >r/r^2+2 ?
1- p=r
2- r>0.
If i consider the stmt-1 then
1/r > r/r^2+2
In order to simplify it further, i can do a cross multlipication, that would result in
==> r^2 +2 >r^2
now looking at the above simplified inequality i can easily say that whether r>0 or r<0;
the above inequality will always be true..... So i chose optionn A. But the answer says C . Can somebody tells me what mistake i am doing? Is there any thing wrong in simplifying the inequality further.
Thanks in advance.
