Q5 of 76 Page 2

Write the following relations as the sets of ordered pairs:

A relation R form a set A = {5, 6, 7, 8} to the set B = {10, 12, 15, 16, 18} defined by (x, y) R x divides y.

Given, (x, y) R x divides y


where x {5, 6, 7, 8} and y {10, 12, 15, 16, 18}


Here,


5 divides 10 and 15.


6 divides 12 and 18.


7 divides none of the value of set B.


8 divides 16.


∴ R = {(5, 10), (5, 15), (6, 12), (6, 18), (8, 16)}
