23 reading spots, Each reading spot consists of 9 chairs placed around it so There are some readers such that in each occupied reading spot there are different numbers of readers. The answer will be 17.
Let's assume that 1st reading spot has 3 people, 2nd has 4 people, 3rd has 5 people, 4th has 7 people, 5th has 8 people, 6th has 9 people.
So, the total number of people = 3+4+5+7+8+9 = 36
For 36 people, only 6 reading spots are occupied
Therefore, remaining = 23 - 6 = 17 are empty.

there are different answers for this question
it depends how do yo think about given question for example
above answer and 1+2+3+4+5+6+7+8= 36 readers
so ,8 spots have different readers.
23-8= 15.
