The value of ` int _(0)^(12a) (f(x))/(f(x)+f(12a-x))dx ` isA. aB. 2aC.

1.	The value of ` int _(0)^(12a) (f(x))/(f(x)+f(12a-x))dx ` isA. aB. 2aC. 3aD. 6a
Answer» Correct Answer - D Let `l =int_(0)^(12a)(f(x))/(f(x)+f(12a-x))dx` … (i) `rArrl=int_(0)^(12a)(f(12a-x))/(f(12a-x)+f(x))dx` … (ii) On adding Eqs . (i) and (ii) , we get `2l=int_(0)^(12a)1dx=[x]_(0)^(12a)` `rArrl=6a`
