પ્રાકૃતિક સંખ્યાગણ પર સંબંધ $R$ એ $\{(a, b) : a = 2b\}$ દ્વારા વ્યાખ્યાયિત હોય તો  ${R^{ - 1}}$ =

A

$\{(2, 1), (4, 2), (6, 3).....\}$

B

$\{(1, 2), (2, 4), (3, 6)....\}$

C

${R^{ - 1}}$ is not defined

D

એકપણ નહીં.

Solution

(b) $R = \{(2, 1), (4, 2), (6, 3),……\}.$

So, ${R^{ – 1}}$ $= \{(1, 2), (2, 4), (3, 6),…..\}.$
