in an examination a candidate obtains 25% marks and fails by 45% marks while another candidate obtains 46% marks and passes by 15% marks more of those required for passing.what are the passing marks?

• I think it is wrongly given as 45% and 15%.It should be marks only.

• if it is marks not % then
  let us assume that total marks be x
  (25x/100)+45=P (passing marks)..........(1)
  (46x/100)=P+(15x/100)
  from (1) substitute the value of P
  (46-15-25)x/100=45
  6x=4500
  x=750
  from (1) passing marks will be
  P=0.25*750+45
  P=232.5 marks

• 45 marks not 45%

• If you want to find the percentage of passing marks then you can find the solution but if you want to find the passing marks then you must have been given the total marks for the exam.

• 60 is the oassing marks
  becoz 25% means 25 marks out of 100
  and 45% means 45..so total required is 60 for passing..
  anothe cndidate got 46+15=61 i.e 1 mark more than passing...
  so 60 is the naswer
