If you read the condition ATTENTIVELY, you will see that there are 16 positions before #17 and 11 after #17.

So, there are 16 + 1 + 11 = 28 people in the line.

Answer. There are 28 people in the line.

P.S. This part of the condition " . . . Alisha is standing at the 7th position from the back." is EXCESSIVE, NON-NECESSARY and is not used in the solution.

It is included to the condition with the only goal to confuse the reader by giving him non-relevant info.
