Given, x R y ⇒ x to y. R=2,3,2,7,3,7,3,10,4,3 ∴ Domain of R=2,3

Q. A relation $R$ is defined from ${2, 3, 4, 5}$ to ${3, 6, 7, 10}$ by $x R y \Rightarrow x$ is relatively prime to $y$ , then domain of $R$ is

${2, 3, 5}$

${3, 5}$

${2, 3, 4}$

${2, 3, 4, 5}$

Given, $x R y \Rightarrow x$ to $y$ .
$R = 2, 3, 2, 7, 3, 7, 3, 10, 4, 3$
$∴$ Domain of $R = 2, 3$

Q. A relation R is defined from {2,3,4,5} to {3,6,7,10} by xRy⇒x is relatively prime to y , then domain of R is

{2,3,5}

{3,5}

{2,3,4}

{2,3,4,5}
