[Ag+] = C+S
[Br-]= S
ksp = (C+S).S = 12*10-14
in general cases, C >>S hence C+S≈C
but here C is comparable to S , so
S(S+10-7) = 12*10-7
therefore S=3*10-7
you can continue from here

Thanks Aditya, But I have done upto that part.. can you please elate it further,
then use K = (lamda)*(molarity)*1000 for each of the ions present , and add them up
