A non zero real number could be written as a/1.
When this gets reversed to be 1/a, it is the multiplicative inverse.
If a set contains ‘n’ elements, then the number of proper subsets of the set is 2^n - 1.
In this problem,
n = 4
2^4 - 1 = 16 - 1 = 15 proper subsets
11x180/12
11x180= 1980
1980/12
165
the answer is 165
