A.4 years
B.8 years
C.10 years
D.None of these

Answer 1

I think it's none of these

Answer 2

solutions :-

The five children's ages will be :-
x, x + 3, x + 6, x + 9, x + 12.
Added together this gives:
5x + 30
Total of ages = 50
5x + 30 = 50
5x = 50 - 30
5x = 20
x = 4.

The youngest child is 4 years old.
