AS, There are some readers such that in each occupied reading spot there are
different numbers of readers. 1+2+3+4+5+6+7+8= 36 readers so, 8 spots have
different readers. remaining are 23-8= 15. 15 spots are empty.

Hi,
I came up with another thought...
the numbers are 8,2,14,6,11,?,14,6,18,12
Now add the 1st number and the last number .. it is 20.
not add the 2nd number which is 2 and the last but one number which is 18 ... it is 20..
So if you keep adding these all the sum equals to 20. So the number next to 11 should be 9. Any thoughts :-)Sravani

Add the first and last number(i.e 8+12=20)
And add the second number and the number which second from last(i.e 2+18)
And so on............
Now the required answer is 9 (i.e 11+9=20) -
