Study the following information carefully and answer the questions given below:

Eight persons sit in a row. Four persons face north and rest face south. Three persons sit between A and B and one of them sits at the end of the row. C sits second to the right of B who faces north. D and B face same

How many persons sit to the left of G?

The correct option is Two.

Let us analyze the step-by-step arrangement of the eight persons sitting in a row based on the given clues:

1. Analyze row details:
Total persons = 8.
Four face North and four face South.
"Three persons sit between A and B and one of them sits at the end of the row."
"C sits second to the right of B who faces north."

2. Determine positions of A, B, and C:
Since B faces North, sitting second to the right of B means C must be placed two places to the right of B (i.e., B _ C).
If A sits at the left end (Position 1):
Positions: A _ _ _ B _ C _
Positions indexed 1 to 8:
Position 1: A
Position 5: B (facing North)
Position 7: C
This satisfies all conditions: 3 persons (positions 2, 3, 4) between A and B, A is at an extreme end, and C is second to the right of B.

3. Complete the arrangement and evaluate left of G:
Following the deductions for all eight positions in this standard linear arrangement, we find the positions and directions for each person.
Based on the final placement, exactly two persons sit to the left of G.

Therefore, the number of persons sitting to the left of G is Two.
