Question

If $A=\{2,3,5\},B=\{2,5,6\}$, then $(A-B)\times (A\cap B)$ is

• A. $\left\{\right(3,2),(3,3),(3,5\left)\right\}$
• B. $\left\{\right(3,2),(3,5),(3,6\left)\right\}$
• C. $\left\{\right(3,2),(3,5\left)\right\}$
• D. $noneofthese$

Answer 1

Answer: (C)

$\left\{\right(3,2),(3,5\left)\right\}$

Ans. $\left(c\right)$.
$A-B=\left\{3\right\},A\cap B=(2,5)$.
$\therefore (A-B)\times (A\cap B)=\left\{\right(3,2),(3,5\left)\right\}$.
