Question

Manoj and Sachin are ranked seventh and eleventh respectively from the top in a class of 31 students. What will be their respective ranks from the bottom of the class?

• A. 20th and 24th
• B. 24th and 20th
• C. 25th and 21st
• D. 26th and 22nd

Hint:

To convert a rank from the top to a rank from the bottom, subtract the rank from the total number of students and add 1.

Answer 1

The Correct Option is C

Step 1: Understanding the ranking system.
The total number of students is 31.
Manoj’s rank from the top is 7th. To find his rank from the bottom, we use the formula: \[ \text{Rank from bottom} = \text{Total students} - \text{Rank from top} + 1 \] \[ = 31 - 7 + 1 = 25 \] So, Manoj’s rank from the bottom is 25th. Sachin’s rank from the top is 11th. Similarly, we use the formula to find his rank from the bottom: \[ \text{Rank from bottom} = 31 - 11 + 1 = 21 \] So, Sachin’s rank from the bottom is 21st. Step 2: Conclusion.
The correct answer is (3) 25th and 21st.
