Directions (Q. 79-81): Study the following information carefully and answer the questions given below. There are six boxes A, B, C, D, E, and F of different heights. Only two boxes are shorter than F. F is taller than B and D. Only one box is shorter than C. E is the shortest among all. A is not the tallest. Q79. Which of the following can be the height of box A?

Explanation

Solution: Step 1: Box B is not 9 m (Clue 1) + taller than D (Clue 2) => Box B > Box D. Step 2: Box D > Box C (Clue 3) + Box B > Box C => only one box shorter than C => E can be the only option as E is shortest. Step 3: Box E is 5 m (Clue 4) => C = 6 m (only possibility). Step 4: Box D > C => D = 7 or 8 m. Step 5: From Clue 2, Box B > Box D and is shorter than F. If D = 8 m => B = 9 m => not valid (contradicts Clue 1). Therefore, D = 7 m, B = 8 m, F = 9 m. Final arrangement: F (9 m) > B (8 m) > D (7 m) > C (6 m) > E (5 m) > A (4 m). A is 4 m. So, Option 5 is the correct answer.
