Who among A, B, C, D, and E is the tallest?
I. A is taller than B. E is not the tallest.
II. C is taller than A. D is not the tallest.
From statement I A>B; from statement II C>A, also both D and E are not the tallest so the remaining i.e. C will be tallest. Together the relation will be: C>A>B>D/E>D/E; so both statements are required.
