Question

Ankit is 18th from right in the class of 50 students. What is the position from left?

• A. 50
• B. 32
• C. 33
• D. 31

Hint:

Always remember the "+1" rule. If you simply subtract 18 from 50, you are removing Ankit entirely. Adding 1 puts him back into the count from the left side.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
In ranking problems, when the total number of people and the position from one end are known, the position from the opposite end can be found by considering that the person is counted once from both sides.

Step 2: Key Formula or Approach:
\[ \text{Total} = (\text{Position from Left}) + (\text{Position from Right}) - 1 \] OR \[ \text{Position from Left} = (\text{Total} - \text{Position from Right}) + 1 \]

Step 3: Detailed Explanation:
1. Total number of students = 50. 2. Position of Ankit from the right = 18. 3. Applying the formula: \[ \text{Position from Left} = (50 - 18) + 1 \] \[ \text{Position from Left} = 32 + 1 = 33. \]

Step 4: Final Answer:
Ankit's position from the left is 33rd.
