Answer 1

Answer:

4yrs

Step-by-step explanation:

$x + (x + 3) + (x + 6) + ( x+ 9) + (x + 12) = 50$

$5x + 30 = 50$

$5x = 20$

$x = 4$

Answer 2

Answer:

Let the ages of children be x, (x + 3), (x + 6), (x + 9), (x + 12) years.

According to Question now,

➳ x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50

➳ 5x + 30 = 50

➳ 5x = 50 - 30

➳ x = 20/5

➳ x = 4 years

Therefore,the age of youngest child is 4 years.
