Given:

A student made twice as many mistakes as he got correct answers.

Total attempted questions = 48

Formula used:

Let the number of correct answers be x.

Then, the number of mistakes = 2x

Total questions attempted = Correct answers + Mistakes

Calculation:

x + 2x = 48

⇒ 3x = 48

⇒ x = 48 / 3

⇒ x = 16

∴ The correct answer is 16.
