Given:
Ratan is one-third of Jatin
The sum of their ages is 84 years
Solution:
Let the age of Jatin be 3x year
As Ratan is one-third of Jatin
Age of Ratan = x year
=> Sum of their ages = 84
=> 3x + x = 84
=> 4x = 84
=> x = 21 year
=> Age of Jatin = 3x = 3 21 = 63 year
Hence, The age of Jatin is 63 years.
