From the given clues it is clear that benedict is not in the same group as winston and valentine (clue 2 and 5) which means winston and valentine are in the same group,also the twin brothers will be in the group of valentine and winston(clue 1)
briscoe and hamilton get eliminated from the group of valntine & winston coz they are brothers (clue 3)so they belong to the group of benedict.
Left ones are Dewey and Decatur. Since group of valentine contains twin brothers
so Dewey goes to their group and Decatur to other group. Ages can be determined using the clue for ages given. Also given in ques that Jones have 4 sons and smiths have 3. hope it helps pankhuri dhingra.
