arithmetic - one year ago kanchana was four times as old as her daughter six years hence kanchanas age will exceed her daughters age by 9 years the ratio of the present ages of kanchana and her daughter is - skillgun

Let the ages of Promila and her daughter 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
