Q4 of 76 Page 2

Mark the correct alternative in the following:

If A = {1, 2, 3} B = {1, 4, 6, 9} and R is a relation from A to B defined by ‘x is greater than y. The range of R is


As per condition of the relation, x > y.

So, required relation will be : {(2, 1), (3, 1)}


Since we know that Range is the set of elements written after comma in each ordered pair.


Therefore, Range = {1}


So, option C is correct.
