Question 1047234
Suppose Set B contains 61 elements and the total number elements in either Set A or Set B is 112. If the Sets A and B have 38 elements in common, how many elements are contained in set A? 
-----
A + B - (A and B) = (A or B)
-----
A + 61 - 38 = 112
------
A = 150-61
----
A = 89 elements
