Given: Mahesh is 12 years old and three times as old as his brother Ramesh.
Let's assume the age of Ramesh as x years.
Then, according to the given condition, Mahesh's age = 3x years.
To find the age at which Mahesh will be twice as old as Ramesh, we can use algebraic equations.
Let's assume that after y years, Mahesh will be twice as old as Ramesh.
So, after y years, Ramesh's age = x + y years.
And after y years, Mahesh's age = 3x + y years.
According to the given condition, Mahesh will be twice as old as Ramesh after y years. So,
3x + y = 2(x + y)
Solving the above equation, we get:
y = x
So, after x years, Mahesh will be twice as old as Ramesh.
Now, we know that Mahesh's age = 3x years.
So, after x years, Mahesh's age will be:
3x + x = 4x years.
Therefore, Mahesh will be 16 years old when he is twice as old as Ramesh.
Hence, the correct answer is option D) 16 years.

3x + y = 2(x + y)
Solving the above equation, we get:

So, after x years, Mahesh will be twice as old as Ramesh.
Now, we know that Mahesh's age = 3x years.
So, after x years, Mahesh's age will be:
3x + x = 4x years.
Therefore, Mahesh will be 16 years old when he is twice as old as Ramesh.
Hence, the correct answer is option D) 16 years.
