यदि \(f:\mathbb{R}\to\mathbb{R}\) और (f(x)=\frac{x}{1+x-2}), तो (f(2)+f\left\(\frac{1}{2}\right\)) का मान क्या है?
If \(f:\mathbb{R}\to\mathbb{R}\) and (f(x)=\frac{x}{1+x-2}), what is the value of (f(2)+f\left\(\frac{1}{2}\right\))?

Correct Answer
B. \(\frac{4}{5}\)
Concept
(f(2)=\frac{2}{1+4}=\frac{2}{5}).
Why this answer is correct
(f\left\(\frac{1}{2}\right\)=\frac{\frac{1}{2}}{1+\frac{1}{4}}=\frac{2}{5}).
Exam Tip
Adding them gives \(\frac{4}{5}\). चरण 1: (f(2)=\frac{2}{1+4}=\frac{2}{5})। चरण 2: (f\left\(\frac{1}{2}\right\)=\frac{\frac{1}{2}}{1+\frac{1}{4}}=\frac{2}{5})। चरण 3: दोनों को जोड़ने पर \(\frac{4}{5}\) मिलता है।
