\(\frac{{x - a}}{{{a^2} - \;{b^2}}} = \frac{{x - b}}{{\;{b^2} - {a^{2\;}}}}\) হলে x = ? 

A \(\frac{{a - b}}{2}\) 

B \(\frac{{b - a}}{2}\) 

C \(\frac{{a + b}}{2}\) 

D a+b 

E    

Solution

Correct Answer: Option C

\(\frac{{x - a}}{{\;{a^2} - {b^2}}} =  - \frac{{x - b}}{{({a^2} - {b^2})}}\)    = x-a = -x+b  =2x = a+b      x = \(\frac{{a + b}}{2}\)
