Verified Answer
12 year old Manick is three times as old as his brother Rahul. How old...
Manick's present age = 12 years, Rahul's present age = 4 years.
Let Manick be twice as old as Rahul after x years from now.
Then, 12 + x = 2 (4 + x) 
12 + x = 8 + 2x 
x = 4.
12 + x = 8 + 2x x = 4.Hence, Manick's required age = 12 + x = 16 years.

12 year old Manick is three times as old as his brother Rahul. How old...
Given information:
- Manick is currently 12 years old.
- Manick is three times as old as his brother Rahul.
To find the age at which Manick will be twice as old as Rahul, we need to determine Rahul's age.
Let's assume Rahul's age is x.
According to the given information, Manick's age is three times Rahul's age:
Manick's age = 3 * Rahul's age
We know that Manick is currently 12 years old, so we can write the equation as:
12 = 3 * x
Solving the equation for x, we find:
x = 12 / 3
x = 4
Therefore, Rahul is currently 4 years old.
To determine when Manick will be twice as old as Rahul, we need to find the age difference between Manick and Rahul and add it to Rahul's age.
Age difference between Manick and Rahul:
Manick's age - Rahul's age = 12 - 4 = 8
To find the age at which Manick will be twice as old as Rahul, we add this age difference to Rahul's age:
Rahul's age + Age difference = 4 + 8 = 12
Therefore, when Rahul is 12 years old, Manick will be twice as old as Rahul.
Hence, the correct answer is option B) 16 years.
- Manick is currently 12 years old.

To determine when Manick will be twice as old as Rahul, we need to find the age difference between Manick and Rahul and add it to Rahul's age.
Age difference between Manick and Rahul:
Manick's age - Rahul's age = 12 - 4 = 8
To find the age at which Manick will be twice as old as Rahul, we add this age difference to Rahul's age:
Rahul's age + Age difference = 4 + 8 = 12
Therefore, when Rahul is 12 years old, Manick will be twice as old as Rahul.
Hence, the correct answer is option B) 16 years.
