Question

Nitin ranks eighteenth in a class of 49 students. What is his rank from the last?

• A. 18
• B. 19
• C. 31
• D. 32
  (e) 33
• E. 33

Hint:

To verify your answer, add the ranks from both ends: $18 + 32 = 50$. This sum should always be Total + 1. Since $49 + 1 = 50$, the answer is correct.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Ranking from the "top" or "start" is mathematically identical to ranking from the "left," and ranking from "last" or "bottom" is the same as ranking from the "right."

Step 2: Key Formula or Approach:
\[ \text{Rank from Last} = (\text{Total} - \text{Rank from Start}) + 1 \]

Step 3: Detailed Explanation:
1. Total number of students = 49. 2. Nitin's rank from the start = 18. 3. Applying the formula: \[ \text{Rank from Last} = (49 - 18) + 1 \] \[ \text{Rank from Last} = 31 + 1 = 32. \]

Step 4: Final Answer:
Nitin's rank from the last is 32nd.
