there r 5 papers Ratio of marks obtained in each subject is 6:7:8:9:10. Total marks obtained is 60%. 50% is pass marks. In how many subjects did he get above 50%.

• 4 subjects he got above 50%.
  
  Total marks in 5 papers = 60% (i.e., 60*5 = 300)
  
  6x+ 7x+ 8x+ 9x+ 10x =60/100(500)
  
  Put x= 8 for solving,
  
  6x= 48; 7x = 56; 8x = 64 ; 9x = 72; 10x = 80
  
  Marks are 6:7:8:9:10 = 48+56+64+72+80
  = 300
  
  So, 4 subjects he got 50% above
