Question : If $x^2 = y+z$, $y^2=z+x$, $z^2=x+y$, then the value of $\frac{1}{x+1}+\frac{1}{y+1}+\frac{1}{z+1}$ is:
Option 1: –1
Option 2: 1
Option 3: 2
Option 4: 4
Correct Answer: 1
Solution : Given: $x^2 = y+z,y^2 = z+x$ and $z^2 = x+y$ Now, $\frac{1}{x+1}+\frac{1}{y+1}+\frac{1}{z+1}$ = ($\frac{x}{x+x^2}+\frac{y}{y+y^2}+\frac{z}{z+z^2})$ = ($\frac{x}{x+y+z}+\frac{y}{y+x+z}+\frac{z}{z+x+y})$ = ($\frac{x+y+z}{x+y+z}$) = 1 Hence, the correct answer is 1.
