Answer:
x = 12
Step-by-step explanation:
Let's assume that the current age of the boy = x
∴ Current age of his father = 3x
After 12 years:
The boy will become = x + 12
and His father will become = 3x + 12.
According to the problem:
3x + 12 = 2(x + 12)
=> 3x - 2x + 12 - 24 = 0
=> x - 12 = 0
=> x = 12
