Mohan is 14th from the left end in a row of 40 boys. What is his position from the right end?
25th
Finding Position from the Right End
This question asks us to find a person's position from the right end of a row, given their position from the left end and the total number of people in the row. These types of problems are common in reasoning and ranking exercises.
Given Information
- Total number of boys in the row: 40
- Mohan's position from the left end: 14th
Step-by-Step Calculation
To find Mohan's position from the right end, we can use a method that considers the total number of boys and his position from the left. Here's how we perform the calculation:
-
Subtract Mohan's position from the left end from the total number of boys. This helps us determine a count related to the other end.
Total boys - Position from Left = Remaining count
$$40 - 14 = 26$$ -
Subtract 1 from the result obtained in Step 1. This final adjustment gives us the position from the right end.
Remaining count - 1 = Position from Right
$$26 - 1 = 25$$
Final Position
Following the steps above, Mohan's position from the right end is 25th.
This means there are boys to Mohan's right, and counting from the right end, he is at the 25th spot.
