B Correct answer
Explanation

Let Minku's present age (in the year 2000) be P. Her age in 2020 (after 20 years) is P + 20, and her age in 1995 (5 years back) is P - 5. Setting up the equation P + 20 = 6(P - 5) gives 5P = 50, which means her present age is 10 years.

AI explanation

Let Minku's present age be x years. Her age after 20 years will be x plus 20, and her age 5 years back was x minus 5. The equation is x plus 20 equals 6 times x minus 5, which simplifies to x plus 20 equals 6x minus 30. Solving for x gives 5x equals 50, making her present age 10 years.
