Answer 1

The Correct Option is C

Concept: Position-based reasoning (Left–Right relation).
Step 1: Identify total number of persons.
After swapping, Beena is at position 15 from the left. Originally, Meena was at 4th from right, so after swap Beena takes that position.
Step 2: Use formula.
\[ \text{Total persons} = \text{Left position} + \text{Right position} - 1 \] \[ = 15 + 4 - 1 = 18 \]
Step 3: Find Reena's position from right.
Reena is 6th from left: \[ \text{Position from right} = 18 - 6 + 1 = 13 \]
Step 4: Final answer.
Thus, Reena is 13th from the right.

Answer 2

Concept: Position-based reasoning using total count.
Step 1: Use total number of persons.
From previous question: \[ \text{Total persons} = 18 \]
Step 2: Use given position.
Neena is 5th from the right.
Step 3: Convert to left position.
\[ \text{Position from left} = 18 - 5 + 1 = 14 \]
Step 4: Final answer.
Thus, Neena's position from the left = 14.

Answer 3

Concept: Position swapping in ranking.
Step 1: Use known positions.
Reena is 6th from the left.
Neena is 14th from the left.
Step 2: Apply exchange.
After swapping positions: Neena takes Reena's position.
Step 3: Final position.
Thus, Neena becomes 6th from the left.
Step 4: Final answer.
Hence, answer is 6.

Answer 4

Concept: Position conversion after swapping.
Step 1: Identify initial positions.
Beena is 7th from the left.
Meena is 4th from the right.
Step 2: Apply swap.
After swapping, Meena takes Beena’s position → 7th from left.
Step 3: Use total persons.
Total persons = 18
Step 4: Convert to right position.
\[ \text{Position from right} = 18 - 7 + 1 = 12 \]
Step 5: Final answer.
Thus, Meena is 12th from the right.
