Sum of the ages of 4 children born at the intervals of 4 years each is 52 years. What is the age of the eldest one?

7 years 14 years 19 years 24 years

19 years

Let the age of eldest one = x years Age of other 3 children = (x - 4), (x - 8), (x - 12) ATQ, x + (x - 4) + (x - 8) + (x - 12) = 52 4x - 24 = 52 4x = 52 + 24 = 76 x = 19 Hence, the age of the eldest one = 19 years.
