RRB Group-D Model Paper 12 with answers for online practice

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
