Total cost in state A = p1(1+t1/100) and in state B = p2(1+t2/100)
From stmt1: we know that t1 > t2, but not sure of p1 and p2.....insufficient.
From stmt2: we know that p1t1 > p2t2 and again not sure of p1 and p2....insufficient.
Combining two, p1(1+t1/100) > p2(1+t2/100)
Correction. It will be E.
if t1 > t2 and p1t1 > p2t2, we cannot say that p1 > p2.....hence, E.
