D Correct answer
Explanation

Let Reena's present age be r. Umesh is 7r years old, and 7r + 6 = 4(r + 6), because his age will then be four times Reena's age. Solving gives r = 6 and Umesh's present age = 7 × 6 = 42 years.

AI explanation

Let Reena's present age be x years, so Umesh's present age is 7x. In 6 years, Umesh's age will be 7x + 6 and Reena's age will be x + 6. The problem states 7x + 6 = 4(x + 6), which expands to 7x + 6 = 4x + 24. Solving this gives 3x = 18, so x equals 6. Umesh's present age is 7x, which is 7 multiplied by 6, giving 42 years.
