Step 1: Analyze the given positions.
Kashish is initially 5th from the left and Mona is 6th from the right.
Step 2: Determine the total number of children in the queue.
When Kashish and Mona swap places, Kashish becomes 13th from the left. The total number of children is \(5 + 13 = 18\).
Step 3: Find Mona`s new position.
After swapping, Mona is now in the position where Kashish was, i.e., 5th from the left.
Step 4: Calculate Mona`s position from the right.
Mona`s position from the right is \( (18 - 5) + 1 = 14 \).
Step 5: Final Answer
The correct answer is (b) 14th.
Final Answer: The correct answer is (b) 14th.
