As we learnt 

Properties of Definite Integration -

\int_{a}^{b}f\left ( x \right )dx= \int_{a}^{b}f\left ( a+b-x \right )dx

\int_{a}^{b}\frac{f\left ( x \right )}{f\left ( x \right )+f\left ( a+b-x \right )}dx= \int_{a}^{b}f\left ( a+b-x \right )dx= \frac{b-a}{2}

-

 

 Simply\: \: I=\frac{10-5}{2}= \frac{5}{2}
