A's age = 36 years and B's age = 52 years.

Step-by-step explanation:

Let their ages 4 years ago = 2x and 3x

4 years later, their ages = 2x+8 and 3x+8

• Therefore, 2x+8 / 3x+8 = 5/7
• It implies, 7(2x+8) = 5(3x+8)
• It implies, 14x+56 = 15x+40
• It implies, x = 16

Therefore, their ages 4 years ago are 2(16)=32 and 3(16)=48.

years respectively. At present, their ages are 36 and 52 years respectively.
