Answer 1

Answer:

23 years

Step-by-step explanation:

---> 3 years ago, the ratio of age of A and B = 5: 4 (5x, 4x)---> The present age of A and B = 5x + 3, 4x + 3---> Present age of C = Present age of A – 8---> Present age of D = 12 – 7 = 5---> Present age of C = 4 * present age of D---> 4*5 = 20 years---> Present age of A = 20 + 8 = 28 years---> 5x + 3 = 28---> 5x = 25---> X = 5---> The present age of B = 4x + 3 = 23 years
