Question: Who is the tallest among six boys P, T, N, D, Q and R ?
Statements:
P is taller than D and N but not-as tall as T.
R is taller than Q but not as tall as T.
Q is not taller than T and R.
Only I and II
Only II and III
Only I and III
All I, II and III
Explanation:
From I, we have: P > D, P > N, T > P i.e. T > P > D > N or T > P > N > D …(i)From II, we have: R > Q, T > R i.e. T > R > Q …(ii)
From III, we have: T > Q, R > Q …(iii)
Clearly, from (i) and (ii), we conclude that T is taller than each one of P, N, D, R and Q. So, T is the tallest.
