A) \[\{1,2,3,4\}\]
B) \[\{2,\,\,4\}\]
C) \[\{2,\,\,3,\,\,4\}\]
D) \[\{1,\,\,2,\,\,4\}\]
Correct Answer: A
Solution :
Given, \[A=\{1,2,3,4\},R=\{(a,b):a,b,\in A,a\times b\]is an even number} then,\[R=\{(1,20,(1,4),(2,3),(2,4),(3,4),(4,4),(2,1),\] \[(4,1),(3,2),(4,2),(4,3)\}\] \[\therefore \] Range of \[R=\{1,2,3,4\}\]You need to login to perform this action.
