Vedclass · Answer

$n(A \cap B)=50$

so total number of common elements in $(\mathrm{A} 	imes \mathrm{B})$

and $\mathrm{B} 	imes \mathrm{A} \Rightarrow \mathrm{n}((\mathrm{A} 	imes \mathrm{B}) \cap(\mathrm{B} 	imes \mathrm{A}))=2500$

$A = \{1,2,3,4......100\}, B = \{51,52,53,...,180\}$, then number of elements in $(A \times B) \cap (B \times A)$ is
