યોગગણ લખો :​  $A = \{ x:x$ એ $3$ ની ગુણિત પ્રાકૃતિક સંખ્યા છે. $\} ,$ $B = \{ x:x$ એ $6$ થી નાની પ્રાકૃતિક સંખ્યા છે. $\} $

Option A
Option B
Option C
Option D

Solution

$A = \{ x:x$ is a natural number and multiple of $3\}  = \{ 3,6,9 \ldots \} $

As $B = \{ x:x$ is a natural number less than $6\}  = \{ 1,2,3,4,5,6\} $

$A \cup B=\{1,2,4,5,3,6,9,12 \ldots\}$

$\therefore A \cup B = \{ x:x = 1,2,4,5$ or a multiple of $3\} $
