john spent a quarter of his life growing up as a boy,
1/6 of his life in college and 1/2 of his life as a teacher.
He spent his last six years in retirement.
How old was he when he died?
:
let a = his age when he died
:
Age = boy + student + teacher + retired
a = 1%2F4a + 1%2F6a + 1%2F2a + 6
Multiply by 12 to get rid of the denominators, results
12a = 3a + 2a + 6a + 12(6)
12a = 11a + 72
12a - 11a = 72
a = 72 his age when he passed away, much missed and remembered, I am sure.
