We need to determine whether signs of wp and signs of st are same. (Both positive or negative)
Statement 1: Clearly insufficient.
Statement 2: Clearly insufficient.
Combining both statements and adding the inequalities would give us
\(ws + pt > 0\)
\(wt + ps > 0\)
\(ws+wt+pt+ps>0\)
\(w(s+t)+p(s+t)>0\)
\((w+p)(s+t)>0\)
We still cannot determine the signs. Thus insufficient.
Option E is Correct.
