In an examination a student had to obtain 45% of the maximum marks to pass .He got 137 marks and failed by 43 marks .Find the maximum marks:

Answer»

He got 137 Mark's and failed by 43marks

so,pass mark =137+43=180mark

180mark is 45%of TOTAL mark

I.e 45/100×(y)=180 (y is total mark)

y=180×100/45

y=4×100

y=400

so, total mark is 400
