In an examination it is required to get 30% of minimum marks to pass. A student got 110 marks and was declared failed by 10 marks difference. Then what is the maximum marks?
Answers
He got 110 marks
If he had got 10 marks then he would have passed the exam
So minimum required marks =120
120=30%of maximum marks
120=30/100×M.M.
120×100/30=M.M.
M.M.=400
Given:
Minimum marks to qualify=30%
Marks scored by student=110
To find:
The maximum marks
Solution:
The maximum marks are 400.
We can find the marks by following the given steps-
We know that a student needs to score at least 30% marks to clear the exam.
Let the total maximum marks be M.
The student scored 110 marks.
Minimum marks required=30% of M
=30/100 of M
=30M/100=3M/10
Now, as per the given information, the student scored 10 less than the minimum marks.
So, minimum marks-10=marks scored by the student
3M/10-10=110
3M/10=110+10
3M/10=120
3M=120×10
3M=1200
M=1200/3
M=400
Therefore, the maximum marks are 400.
