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...

why unnecessarily complicate things...it is given he spent one twefth of his life as a teenager..now a person is a teenager when he is aged 13 to 19...a total of 7 years...if these 7 years as a teenager form one 12th of his life then he must be 12*7=84 years old when he died..no need for the equations
