Let Ramesh's present age be $x$. Since Ramesh's father's present age is three times Ramesh's age, his father's present age is $3x$.

According to the problem, after 12 years, Ramesh's father's age will be twice Ramesh's age. So, in 12 years:

• Ramesh's age will be $x + 12$,
• His father's age will be $3x + 12$.

The problem states that after 12 years, the father's age will be twice Ramesh's age: $3x + 12 = 2(x + 12)$

Solve the equation:

1. Expand both sides: $3x + 12 = 2x + 24$

2. Subtract $2x$ from both sides: $x + 12 = 24$

3. Subtract 12 from both sides: $x = 12$

So, Ramesh's present age is $12$ years.

Since Ramesh's father's age is three times Ramesh's age, his father's present age is: $3 \times 12 = 36$

Conclusion:

• Ramesh's present age is 12 years.
• His father's present age is 36 years.
