1.Relation and Function
easy
જો $R = \{(1, 3), (2, 2), (3, 2)\}$ અને $S = \{(2, 1), (3, 2), (2, 3)\}$ એ ગણ $A = \{1, 2, 3\} $પરના સંબંધ હોય તો $RoS =$
A
$\{(1, 3), (2, 2), (3, 2), (2, 1), (2, 3)\}$
B
$\{(3, 2), (1, 3)\}$
C
$\{(2, 3), (3, 2), (2, 2)\}$
D
$\{(2, 3), (3, 2)\}$
Solution
(c) Here $R = \{ (1,\,3),\,(2,\,2);\,(3,\,2)\} $,
$S = \{ (2,\,1);\,(3,\,2);\,(2,\,3)\} $
Then $RoS = \{ (2,\,3);\,(3,\,2);\,(2,2)\} $.
