But, from I and II, it is obvious that J is the tallest among M, J, K, P and T.Incorrect

=> U is tallest. [Since U is taller than P, Q & S ans P is taller than R and T]
From II: __ R < U, P & Q — (1) ; Q > P — (2)
From (1) and (2) __ R P Q U Hence U is tallest.Incorrect
From I: P > R, P > T, U > P, U > Q, U > S
=> U is tallest. [Since U is taller than P, Q & S ans P is taller than R and T]
From II: __ R < U, P & Q — (1) ; Q > P — (2)
From (1) and (2) __ R P Q U Hence U is tallest.
