Question
Six persons P, Q, R, S, T, and U have different
heights. P is taller than R. P is shorter than S. U is taller than S. Q is taller than T but shorter than R. Who is the tallest person?Solution
P is taller than R. P is shorter than S. U is taller than S. Q is taller than T but shorter than R. Inferences: From clues 1, 2, and 3, U is taller than S, and S is taller than P, and P is taller than R. From clue 4, Q is shorter than R, and T is shorter than Q. The final arrangement is as follows: (Tallest) U > S > P > R > Q > T (Shortest) U is the tallest person.
