'H' is 16th from top and 12th from the bottom in merit in the class. How many students are there in the class ?

Answer: B

There are 27 students.

H is counted once from each end, so there are 15 students above H and 11 below.

\[ \text{total} = 16 + 12 - 1 = 27 \]

28 counts H twice, the usual slip, and 29 adds one more again.

The general rule: if a person is p-th from the top and q-th from the bottom, the total is p + q - 1.
