Given: Ratio between the Present ages of A & B is 5 : 4 The age of A, 3 years ago is 2 years more than the age of B 4 years hence Calculation: Ratio between the Present ages of A & B is 5 : 4 ⇒ Ages of A and B can be represented as 5x and 4x respectively Now, the age of A, 3 years ago is 2 years more than the age of B 4 years hence (5x - 3) = (4x + 4) + 2 ⇒ x = 9 Total age of A and B = 5x + 4x = 9x ∴ Total age = 9 × 9 = 81 years
