There are 5 Sub with equal high marks. Mark scored by a boy is 3:4:5:6:7 (Not sure). If his total aggregate if 3/5 of the total of the highest score, in how many subjects has he got more than 50%?

• ans is 3 subject
  he get 3/5 of aggregate means 60 % marks
  let every sub max marks =100
  total marks=5*100=500
  get marks =500*60/100=300
  
  marks in 1 st sub= 300*3/3+4+5+6+7=36%
  2nd=300*4/25=48%
  3rd=60%
  4th=72%
  5th=84%
  so in 3 subject boy get above 50% marks
