Answer 1

Answer:

the first one is the youngest one

Answer 2

Answer:

9 years.

Step-by-step explanation:

Let the age of youngest boy be 3x

Age of second boy = 4x

Age of third boy = 7x

Given, average age is 14 years.

So, (3x + 4x+ 7x) / 3 = 14

14x / 3= 14

14x = 42

So x= 3

Age of youngest boy is 3x = 3×3 =9 years.
