Correct Answer: $\frac{5}{2}$


Solution : Given: $x+\frac{1}{x}=3$
To find: $\frac{3x^{2}-4x+3}{x^{2}-x+1}$
Dividing with $x$ on both numerator and denominator,
= $\frac{3x-4+\frac{3}{x}}{x-1+\frac{1}{x}}$
= $\frac{3(x+\frac{1}{x})-4}{(x+\frac{1}{x})-1}$
= $\frac{(3×3)-4}{3-1}$
= $\frac{5}{2}$
Hence, the correct answer is $\frac{5}{2}$.
