Who is tallest among six boys P, T, N, D, Q and R?

I. P is taller than D and N but not as tall as T.

II. R is taller than Q but not as tall as T.

III. Q is not taller than T and R.



A Only I and II
B Only II and III

C Only I and III
D All I, II & III
E Only I & either II or III

Ans. A

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.
