Rahul scored 75% marks in his board exams comprising 5 subjects. He applied for re-evaluation and got 25 marks in one subject, and 5 marks less in another subject. For the remaining three subjects, the marks were unchanged. What is his new percentage?
75
77
79
70
55

• let each subject carries 100 marks then
  total marks for 5 subjects=500
  rahul scored 75% of 500=375
  after re-evaluation he got 375+25-5=395
  therfore 375/500*100=79%
  so answer is option C

• consider 75 % in each sub
  25 increase and 5 less ie 20 increase in total
  distribute 20 in 5 sub ie 4 increement of marks in each sub
  75+4 =79

• 5subjects each subject 100 marks total=500
  he got 75% 75%of500=375
  total marks=375+25-5=395
  average=395/5=79

• total marks obtained before evaluation=(75*5)=375
  new total marks after evaluation=(375+25-5)=395
  new percentage=(395/5)%=79%

• 79 is the answer

• 79%
  for 5 subjects total=500
  75% of 500= 375
  375+25-5=395
  395/500=.79=79%

• Let us assume he got equal marks in all subjects that is 75.
  Now in one subject he got 25 marks more and in one subject 5 marks less remaining three subject unchanged.
  Hence, 75+75+75+100+70=395
  (395/5)*100=79%.

• ans:79%
  25 marks gained and 5 marks losted
  so total marks gain=25-5=20 marks
  for total 5 subjects 20 marks were increased so the new avg is 75+20/5=75+4
  =79

• total marks he got before revaluation is 75%*5=375
  Total marks incremental after Reval is =25-5=20
  So after Reval total marks =375+20=395
  So%=39500/500=79

• five subjects
  consider each subject is equal to 100 marks then total=500
  he got 75% 75%of 500=375
  total marks=375+25-5=395
  average=395/5=79

• let all marks be 100..that is 75%.
  After revaluation,he gained 25-5=20 marks..
  The increased mark i.e 20 can be converted as percentage..as 4%(since 20/100=4%)
  so..now..add both values..75%+4%=79%..

• >Sum of 5 subjects/ 5=75
  >Sum of 5 subjects= 75*5........(1)
  After re-evaluation,
  New sum of 5 subjects= (75*5)+25-5=395
  Therefore, new percentage= 395÷5= 79

• let every sub=100
  total marks=5*100=500
  75% of 500=375
  new marks=375+25-5=395
  395/500*100=79%
