Explanation:

Let the age of A and B two years hence will be 3x years and 4x years respectively.
8 years ago, age of A = (3x – 10) years
8 years ago, age of B = (4x – 10) years
According to question,
(3x-10)/(4x-10)= 2/3
⇒ 9x – 30 = 8x – 20
⇒ x = 10
Present age of A = 3x – 2 = 3 × 10 – 2 = 28 years
