It appears that A = B = {1,2,3,4,5,6}
So n(AxB) = n(A) * n(B) = 6*6 = 36
Not sure what r1 and r2 have to do with it.
if relation r1 and r2 from set A to set B are defined as r1{(1,2),(3,4),(5,6)} and r2 ={(2,1),(4,3),(6,5)}, then n(AXB)
Options
A)35
B)91
C)53
D)55

Are you sure ??
I mean is something wrong in statement
I mean is something wrong in statement
You got me. A and B appear to be sets, and r1 and r2 take A→B
but usually in set notation, AxB is the set of all ordered pairs (a,b) where a∈A and b∈B.
So defining r1 and r2 doesn't seem to me to have anything to do with AxB
