Q 245 / 325

UPSC CSE Prelims 2014

Consider that:

  1. A is taller than B.
  2. C is taller than A.
  3. D is taller than C.
  4. E is the tallest of all.

If they are made to sit in the above order of their height, who will occupy the mid position?

EXPLANATION

Correct Option (C)

The given statements establish the following height relationships:

  1. A is taller than B (A > B)
  2. C is taller than A (C > A)
  3. D is taller than C (D > C)
  4. E is the tallest of all.

Combining these inequalities sequentially:

  • From (1) and (2): C > A > B
  • Incorporating (3): D > C > A > B
  • Incorporating (4), as E is the tallest: E > D > C > A > B

Thus, the complete order of individuals from tallest to shortest is E, D, C, A, B. With five individuals arranged in order of height, the person in the mid-position is the third individual. In this derived sequence, C occupies the third position, making it the mid-position.

Incorrect Options:

  • A: A is the fourth tallest in the sequence (E > D > C > A > B), not the third, and therefore does not occupy the mid-position.
  • B: B is the shortest, occupying the fifth position in the sequence (E > D > C > A > B), and thus is not in the mid-position.
  • D: D is the second tallest in the sequence (E > D > C > A > B), not the third, and therefore does not occupy the mid-position.
