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.
