1 year ago, Promila was 4 times as old as her daughter Jenilia. In 6 years, Promila's age will exceed her daughter’s age by 9 years. The ratio of the present ages of Promila and her daughter is :
","rationale_html":"Let the ages of Promila and Jenilia 1 year ago be 4x and x years, respectively.
Then, [(4x + 1) + 6] - [(x + 1) + 6] = 9 ⇔ 3x = 9 ⇔ x = 3.
∴ Required ratio = (4x + 1) : (x + 1) = 13:4.
