      hai all,

      LCM of 6,12,7 is 84

      DONT TAKE -5 AND -4 AS -9(according to BODMAS rule brackets need to be solve first)

      then the equation becomes

      x=2(84x-14x-7x-12x-420-336)/84

      solve this equation u will get X as 84.

      Hi all
       
      Let the age of the man be x
       
      then we get the equation
       
      x = 2[x-(x/6)-(x/12)-(x/7)-5-4]
       
      Solving the above equation
      we get x = 84
      Therefore, the age of the man when he died was 84 years...
      Lemme know if this right
