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?
Answer & explanation
Correct answer: option 3
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.
