John spent a sixth of his life in childhood, a twelfth as a youth, and a seventh as a bachelor.?

Question

five years after his marriage,his son was born but died 4 years before his own deah at half his age.

How old is John when he died???

Answer 1

John's age when he died = J

John's age at his marriage = M

John's son's age when he died = S

Childhood + Youth + Bachelor = M

J/6 + J/12 + J/7 = M

5 Years After his Marriage + Son's Age when he died = John's age - 4

M + 5 + S = J - 4

Son's age when he died = John's age when he died / 2

S = J / 2

So we have 3 equations and three unknowns as

1.  J/6 + J/12 + J/7 = M

2.  M + 5 + S = J - 4

3.  S = J / 2

Put 1 and 3 to equation 2:

J/6 + J/12 + J/7 + 5 + J/2 = J - 4

Simplify:

84*J - 14*J - 7*J - 12*J - 42*J = 756

J = 84

So he was 84 when he died, his son was 42 when he died and he had married at 33.
