Step-by-step explanation:

Given  

I started working at 18.i spent 1/6 of my working life in a factory. I spent 1/3 of my working life in office and I spent 1/3 of my  

Let x be the number of years worked. So we get

x/6 + x/3 + x/3 + 9  = x

By taking LCM we get

x + 2x + 2x / 6 + 9 = x

5 x / 6 + 9 = x

5 x + 54 = 6 x

x = 54

So his age will be 54 + 18 = 72 years
