arithmetic - ten years ago anu was half of banu in age if the ratio of their present ages is 34 what will be the total of their present ages - skillgun

Let the ages of Anu and Banu 10 years ago be x and 2x years respectively.
Then, (x + 10)/(2x + 10) = 3/4
4 (x + 10) = 3(2x + 10)
2x = 10
x = 5
Sum of their present ages = (x + 10) + (2x + 10) = (3x + 20) = 35 years.
