Arithmetic Aptitude :: Sets, Relations and Functions
- A set consisting of a definite number of elements is called a
- If A, B, C be three sets such that A ∪ B = A ∪ C and A ∩ B = A ∩ C, then.
- If A = {1, 2, 5} and B = {3, 4, 5, 9}, then A ? B is equal to If A = {x: x = 3n, n ? 6, n ? N} and B = {x: x = 9n, n ? 4, n ? N}, then which of the following is false?
- If A = {x ? C: x2 = 1} and B = {x ? C: x4 = 1}, then A ? B is equal to
- If A and B are two sets containing respectively m and n distinct elements. How many different relations can be defined for A and B?
- { (a, b) : a² +b² = 1} on the set S has the following relation
- If Y is the smallest set such that Y U {1, 2} = {1, 2, 3, 5, 9}, then Y is equal to
- If R is the relation “is greater than” from A ={1,2,3,4,5}to B={1,3,4} , Than R-1 is
- If R is a relation on a finite set having a elements , then the number of relations on A is
- If R is a relation on a finite set having a elements , then the number of relations on A is
