Adam answered 80% of the questions correctly. He answered 6 questions wrongly. Find the total number of questions in the quiz
0.2x = 6
x = 6 / 0.2
x = 30
To find the total number of questions in the quiz, we need to use the information given.
We know that Adam answered 80% of the questions correctly, which means he got 80% of the questions right. So, if we assume that the total number of questions in the quiz is "x," then Adam answered 80/100 * x correctly.
Therefore, the number of questions Adam answered correctly is 0.8x.
We also know that Adam answered 6 questions wrongly. So, the total number of questions he answered incorrectly is 6.
Now, we can set up an equation to find the value of x:
Number of questions answered correctly + Number of questions answered wrongly = Total number of questions
0.8x + 6 = x
Simplifying the equation:
0.8x - x = -6
0.2x = -6
Dividing both sides by 0.2, we get:
x = -6 / 0.2
x = -30
The negative value doesn't make sense in this context, so we discard it.
Therefore, the total number of questions in the quiz is 30.
