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

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

Answer: A

Correct answer: 25th and 21st

In a class of 31, a rank of \( r \) from the top is \( 31-r+1 \) from the bottom. Manoj at 7 becomes \( 31-7+1 = \mathbf{25} \)th and Satya at 11 becomes \( 31-11+1 = \mathbf{21} \)st.
