arithmetic - the age of ravi kumar is three times the sum of the ages of his two sons five years hence his age will be double of the some of the ages of his sons ravi kumars present age is - skillgun

Let the sum of present ages of the two sons be x years.
Then, Ravi kumar’s present age = 3x years.

=>3x + 5 = 2x + 20
=>x = 15.
Hence, Ravi kumar’s present age = 45 years.
