Discussion
Raman ranks sixteenth from the top and forty-ninth from the bottom in a class. How many students are there in the class ?
Answer: A
Correct answer: 64
Raman is counted from both ends, so the class holds \[ 16 + 49 - 1 = \mathbf{64} \] students, the 1 being subtracted because Raman himself is counted twice.
