B Correct answer
Explanation

Let Meena's age be 3x and her mother's be 8x. The difference 8x - 3x = 35 gives 5x = 35, so x = 7. Their current ages are 21 and 56; after 4 years, they will be 25 and 60, which simplifies to 5:12.

AI explanation

Let the present ages of Meena and her mother be 3x and 8x. The difference of their ages is 35 years, giving the equation 8x - 3x = 35, which means 5x = 35 and x = 7. Their present ages are 21 and 56, and after 4 years they will be 25 and 60. The ratio of their ages after 4 years is 25 : 60, which simplifies to 5 : 12.
