Let $U$ be the universal set and $A\cup B\cup C=U$. Then, ${\left\{\left(A-B\right)\cup \left(B-C\right)\cup \left(C-A\right)\right\}}^{\text{'}}$ is equal to

The shaded region in the given figure is

In a town of $10,000$ families it was found that $40\%$ family buy newspaper $A, 20\%$ buy newspaper $B$ and $10\%$ families buy newspaper $C, 5\%$ families buy $A$ and $B, 3\%$ buy $B$ and $C$ and $4\%$ buy $A$ and $C.$ If $2\%$ families buy all the three newspapers, then number of families which buy $A$ only is
