When Ravi was 8 years old, his father was 31 years old,. Now his father is twice Ravi's age. How old is Ravi now?

• When Ravi was 8 years old, his father was 31 years old,.
  Means father's age is 23 years more than Ravi.
  Now his father is twice Ravi's age.
  It means difference between their ages is equal to present age of Ravi.
  So Ravi's present age = 23 years. and father's age = 2*23 = 46 yrs
