Solution
Let's solve this step by step:
-
According to the problem, the ratio of Sumit's age to Prakash's age is 2:3. Let's assume the common multiplier to be 'x'. So, Sumit's age is 2x and Prakash's age is 3x.
-
The problem also states that Sumit is 6 years younger than Prakash. So, we can write the equation as 3x - 2x = 6. Solving this equation, we get x = 6.
-
Substituting x = 6 in 2x and 3x, we get Sumit's age as 12 years and Prakash's age as 18 years.
-
The problem asks for the ratio of Sumit's age to Prakash's age after 6 years. After 6 years, Sumit will be 18 years old and Prakash will be 24 years old.
-
Therefore, the ratio of Sumit's age to Prakash's age after 6 years will be 18:24, which simplifies to 3:4.
So, the correct answer is 3:4.
