Given that:
A test was given to 30 students.
5/6 of the students gave all correct answer.
To Find:
How many students did one or more than one mistake.
Let us assume:
x students did one or more than one mistake.
Finding the value of x:
According to the question.
↠ 5/6 of 30 + x = 30
↠ 25 + x = 30
↠ x = 30 - 25
↠ x = 5
Hence,
5 students did one or more than one mistake.
