Detailed Solution

Each element in subsets appear as the number of subsets of S
1 element subsets =  10C0
2 element subsets =  10C1
3 element subsets =  10C2
---------------
---------------
11 element subsets =  10C10
Number of times an element ‘i’ appears is 210  times
 K=(1+3+5+7+9++21)210=(121)(1024)
