Question

ages of A and B are in ratio 3:1.fifteen years hence, the ratio will be 2:1.their present ages are?​

Answer 1

GIVEN

Age of A: Age of B = 3:1

and 15 years later Age of A: Age of B = 2:1

Let  Present Age of A = 3x and age of B be x  from given

15 years later  3x +15 : x + 15 = 2 : 1

            $\frac{3x+15}{x+15} = \frac{2}{1}$

            3x + 15 = 2x + 30

              x = 15

              3x = 45

Present age of A is 45 years and B is 15 years.
