Let A=\{2,3,6,7\} and B=\{4,5,6,8\}

. Let

R be a relation defined on A \times B

by \left(a_1, b_1\right) R \left(a_2, b_2\right)

if and only if a_1+a_2=b_1+b_2

. Then the number of elements in

R

is _________

$Let A=\ 2,3,6,7\ and B=\ 4,5,6,8\ . Let R be a relation defined on A × B by (a_1, b_1) R (a_2, b_2) if and only if$

Correct answer

0

Step-by-step solution

\begin{aligned} & A=\{2,3,6,7\} \\ & B=\{2,5,6,8\} \\ & \left(a_1, b_1\right) R\left(a_2, b_2\right) \\ & a_1+a_2=b_1+b_2\end{aligned}

$Let A=\ 2,3,6,7\ and B=\ 4,5,6,8\ . Let R be a relation defined on A × B by (a_1, b_1) R (a_2, b_2) if and only if$
Total 24 + 1 = 25
