Question

the sum of 5 children age is 50 years at theintervals of 3 years. what is the age of youngest child​

Answer 1

Answer:

Step-by-step explanation:

Let age of youngest one be x

So age of the other 4 at interval of 3 will be x+3 ,x+6,x+9,x+12

ATQ: x+x+3+x+6+x+9+x+12=50

5x+30=50

5x=20

X=4

Therefore age of youngest one is x that is 4 years

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.
