A = {x|x ∈ U and is an even positive integer}
The universal set(U) consists of only positive integers.
Given, A = {x|x ∈ U and x is an odd positive integer}.
That means the set A contains all those elements which belongs to the universal set and should be a positive odd number.
refers to the complement of A. It means that it will contain all those elements that belong to U but does not belong to A.
All the positive odd integer is made up of two types of number ,i.e, positive and negative number.
So,this set will contain all the element belonging to U and should be an even positive integer.
Therefore,Ac = {x|x ∈ U and is an even positive integer}.
