A Correct answer
Explanation

Let Shobo's present age be x, so his mother's age is 6x. Five years from now, Shobo's age is x + 5, which equals one third of 6x, or 2x; therefore x = 5 and his mother is 30.

AI explanation

Let Shobo's present age be $x$ years, making his mother's age $6x$ years. In 5 years, Shobo's age will be $x + 5$, which equals one third of his mother's present age, giving the equation $x + 5 = 6x / 3$. This simplifies to $x + 5 = 2x$, meaning $x = 5$. Shobo is 5 years old and his mother is $6 \times 5 = 30$ years old.
