Multiple choice general knowledge math & puzzles

Condition: (i) A, B, C, D, E, F and G are seven members standing in a row (not necessarily in the same order) facing north. (ii) C and B have as many members between them as G and C have between them. (iii) D, who is 3rd from the extreme left, is 3rd to the left of E. (iv) A and D are neighbors and F and C are neighbors. Question: Who is at the extreme right?

  1. Data inadequate

  2. G

  3. B

  4. None of these

Explanation

Given the conditions: D is at position 2 (3rd from left) and E is at position 5 (3rd to D's right). A neighbors D (positions 1 or 3). F neighbors C. The distance between B and C must equal the distance between G and C. Multiple valid arrangements exist that satisfy all constraints - for example, with C at position 3, B at 1, F at 4, G at 5 (but G conflicts with E), or with C at position 1, B at 3, F at 0, etc. Since different arrangements place different people (B, C, G, F) at the extreme right, the data is inadequate to determine a single answer.

AI explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Data inadequate - This option is correct because the given information does not provide enough clues to determine who is at the extreme right.

Option B) G - This option is incorrect because there is not enough information given to determine if G is at the extreme right.

Option C) B - This option is incorrect because there is not enough information given to determine if B is at the extreme right.

Option D) None of these - This option is incorrect because the given information does not allow us to determine who is at the extreme right.

The correct answer is A) Data inadequate.
