(C) Let the present ages of the father and the two sons be $F$,$S_1$,and $S_2$ respectively.Five years ago,the sum of their ages was $(F-5) + (S_1-5) + (S_2-5) = x$.This simplifies to $F + S_1 + S_2 - 15 = x$,which means the present sum of their ages is $F + S_1 + S_2 = x + 15$.We need to find the sum of their ages after five years from now.The sum after five years will be $(F+5) + (S_1+5) + (S_2+5) = (F + S_1 + S_2) + 15$.Substituting the present sum $(x + 15)$ into this expression:Sum $= (x + 15) + 15 = x + 30$.Therefore,the sum of their ages after five years will be $x + 30$ years.

Five years ago,the sum of the ages of a father and two sons was $x$ years. Then,after five years,the sum of the ages of all will be $\ldots \ldots \ldots$ years.
