The age of eldest child is (x+6) and the second child is (x+3)
Step-by-step explanation:
When all 3 children are 3 years apart and the youngest is known to be "x" age :
1. The difference between the youngest and the second child is 3 years apart so you have to add 3 to the second child,
Second child = (x+3) years old
2. It works the same way as for the eldest child, the difference between second and eldest is also 3 years apart so you have add 3 to the eldest child,
Eldest child = x+3+3
= (x+6) years old
(Hope this can help)
