Solutions :-
Let the maximum marks be x
Given :
Total pass percentage = 35% of x
Student got 57 marks and failed by 13 marks. Therefore, Total Marks to pass exam = 57 + 13 = 70
A/q
=> 35% of x = 70
=> 0.35 × x = 70
=> 0.35x = 70
=> x = 70/0.35 = 200
Hence,
Maximum marks = 200

A student has to obtain 35% of the total marks to pas s he got 57 marks and failed by 13 marks.
We have to find the maximum obtained.
method 1 : percentage method :
total marks need to qualify the exam = 35 % of total
The student got 57 marks and failed by 13.
It means, 57 + 13 = 70 = total qualifying marks
∴ 35 % of total marks = 70
⇒1 % of total marks = 2
⇒100 of total marks = 200
∴ total marks = 200
Therefore the maximum mark obtained are 200
method 2 : by fraction method :
The student has to obtain 35% of total mark.
∵ 35 % = 7/20 ,
it means, he has to obtain 7 out 20 mark to qualify the exam.
her get, 57 marks and failed by 13 marks.
it means, total mark obtained to qualify the exam = 57 + 13 = 70
∵ 70 is 7/20 of total marks.
∴ total marks = 70 × 20/7 = 200
Therefore the maximum marks obtained are 200.
