Question

He sum of ages of 5 children born at the intervals of 3years each is 50 years. What is the age of the youngest child?

Answer 1

Step-by-step explanation:

Since, the children were born at the interval of three years ,let us assume their age as x, x+3,x+6,x+9 and x+12.

According to the given information:

Sum of ages of five children is 50

therefore,

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

5x+30 = 50

5x = 50-30

5x=20

x=4

Thus, the age of the youngest child 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.
