Option
1) 45 years
2) 55 years
3) 52 years
4) 59 years
5) None of these

• let their age is 3x,4x,5x respectively
  avg is=28=(3x+4x+5x)/3
  x=7
  so ram=21
  rohan=28
  raj=35
  sum of ram & rohan after 5 years=21+5+28+5=59 years

• let ratio's be x
  A/c to question,
  3x+4x+5x= 28*3
  x= 7
  Ram = 3*7=21,rohan=4*7=28, raj= 5*7=35
  the sum of the ages of Ram and Rohan together after 5 years = (21+5)+(25+5)=59

• sum of ram,rohan and raj ages are 21+28+35=84
  after 5 years sum of ram and rohan age is (21+5)+(28+5)=59 ans
