Question

Thirty children are standing in a row facing North. If in this row Neelam is seventeenth from the left then what is the position of Neelam from the right?

• A. 17
• B. 13
• C. 14
• D. 15

Hint:

The '+1' in the formula is crucial because when you subtract the left position from the total, you are counting the number of people to the right of the person, not including the person themselves. Adding 1 gives their actual rank from the right.

Answer 1

The Correct Option is C

Step 1: Concept Identification:
This problem involves linear arrangement ranking. A formula exists to determine an item's position from one end given its position from the opposite end and the total count.
Step 2: Governing Principle:
The applicable formula is:
Position from Right End = (Total Count) - (Position from Left End) + 1
Step 3: Application and Calculation:
Total children = 30.
Neelam's left-end position = 17.
Applying the formula:
Neelam's right-end position = \(30 - 17 + 1\)
= \(13 + 1\)
= 14.
Step 4: Conclusive Result:
Neelam's position from the right is 14th.
