Correct Answer: –3

Solution : Given: $x^{3}+y^{3}+z^{3}=13$, $ x+y+z=1$, $xyz=1$
We know, $x^{3}+y^{3}+z^{3}-3xyz= (x^{2}+y^{2}+z^{2}-xy-yz-zx)$
$⇒x^{3}+y^{3}+z^{3}-3xyz= (x+y+z)((x+y+z)^{2}-3(xy+yz+zx))$
Substituting values of $x^{3}+y^{3}+z^{3}$, $ x+y+z$ and $xyz$,
$⇒13-3(1)=(1)((1^{2}-3(xy+yz+zx))$
$⇒xy+yz+zx=\frac{10-1}{-3}$
$\therefore xy+yz+zx=-3$
Hence, the correct answer is –3.
