a) 10yrs b) 6yrs c) 8yrs d) 9yrs

• a:b:c=1:2:3
  a=1x;b=2x;c=3x;
  after three years
  (x+3)+(2x+3)+(3x+3)=45;
  x=6;
  so present age of a will be x+3=6+3=9;

• The sum of the present ages of A, B, C is 45 yrs. Three years ago, sum of their ages was 45 -3*3= 36 yrs
  Three years ago their ages were in the ratio 1:2:3.
  so three yrs ago, age of A was 26*1/6= 6 yrs
  Present age of A = 6+3=9 yrs

• age of a=9 as k+2k+3K+9=45
• 13 years agoHelpfull: Yes(4) No(0)
• Given sum (A+B+C)=45
  Ratio 3 years ago 1:2:3
  Present age = 1x + 2x + 3x +9 =45(Since 3 years ago ratio 3+3+3=9)
  6x+9=45; x=6
  Present age of A=x+3 ;6+3=9 so option d)9yrs
