Question:
In a row Ajith is \(16^{th}\) from left and \(18^{th}\) from right, then total number of persons in the row is
In a row Ajith is \(16^{th}\) from left and \(18^{th}\) from right, then total number of persons in the row is
Show Hint
If one person's position from both ends is given, use: Total \(=\) Left position \(+\) Right position \(-1\).

The Correct Option is D
Solution and Explanation
Concept:
When a person's position from the left side and from the right side is given, the total number of persons in the row is calculated by: \[ \text{Total persons}=\text{Position from left}+\text{Position from right}-1 \] We subtract \(1\) because the same person is counted once from the left side and once from the right side.
Step 1: Write the given positions.
Ajith is \(16^{th}\) from the left. \[ \text{Position from left}=16 \] Ajith is \(18^{th}\) from the right. \[ \text{Position from right}=18 \]
Step 2: Apply the formula.
\[ \text{Total persons}=16+18-1 \] \[ \text{Total persons}=34-1 \] \[ \text{Total persons}=33 \]
Step 3: Final answer.
Therefore, the total number of persons in the row is: \[ 33 \] \[ \therefore \text{Correct Answer is (D)} \]
