Respuesta :

Answer:

Age of oldest child = 15

Age of middle child = 12

Age of youngest child = 5

Step-by-step explanation:

let the age of youngest child be 'x';

now, according to the question;

age of oldest child = 3x

age of middle child = 3x - 3

also;

⇒ 32 = age of youngest child + age of middle child + age of oldest child

⇒ 32 = x + 3x - 3 + 3x

⇒ 7x = 35

⇒ x = 5

so,

age of youngest child = x = 5

age of middle child = 3x - 3 = 12

age of oldest child = 3x = 15
