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