There are seven up on a ladder, A, B, C, D, E, F and G (not in that order). A is further up than E but is lower than C. B is in the middle. G is between A and B. E is between B and F. If F is between E and D, the person on the bottom step of the ladder will be

Correct Option (3)

: D

To determine the individual on the bottom step of the ladder, the relative positions of all seven persons (A, B, C, D, E, F, G) must be established based on the provided statements:

• "A is further up than E but is lower than C" implies the positional sequence: C > A > E.
• "B is in the middle" signifies that B occupies the 4th position among the seven steps.
• "G is between A and B". Given C > A, A must be above B, leading to the sequence: A > G > B.
• "E is between B and F". Since A > G > B and C > A > E, E is below B, establishing the sequence: B > E > F.
• "F is between E and D". Combining this with B > E > F, the sequence becomes: E > F > D.

Integrating these derived sequences results in the complete order from the top step to the bottom step:

C (1st) > A (2nd) > G (3rd) > B (4th) > E (5th) > F (6th) > D (7th)

Thus, D is positioned on the bottom step of the ladder.

Incorrect Options:

Based on the established order C > A > G > B > E > F > D:

• (1) B is in the middle, occupying the 4th position, not the bottom.
• (2) F is in the 6th position from the top, not the bottom.
• (4) E is in the 5th position from the top, not the bottom.
