When you executed
fvars=vars/.NDSolve[deqns,vars,{t,start,end}][[1]]
{InterpolatingFunction[{{0.,10.}},<>][t],InterpolatingFunction[{{0.,10.}},<>][t]}
you replaced the previous definition of favrs (which was fvars = {a[t_],b[t_]}) with the result of NDSolve. Your solutions now are in fvars[[1]] and fvars[[2]
I am not sure what you are trying to accomplish by setting fvars = {a[t_],b[t_]}. This involves as much typing as
fvars=vars/.NDSolve[deqns,vars,{t,start,end}][[1]]
{SolvedA[t_],SolvedB[t_]}=fvars
By the way, I would recommend that you use a different variable for the solved form of a[t and b[t]. Otherwise, if you execute the notebook a second time, the solved values of a,b, will be used inside NDSolve and you will get unexpected results.
