old man, then how many years did he spend as an active man?
(1/4)y+(1/8)y+(1/2)y =p; where y =tot life time.

Man Wrinkle spent one-fourth of his life as a boy, one-eighth as a
youth, and one-half as an active man. If Man Wrinkle spent 8 years as an
old man, then how many years did he spend as an active man?
(1/4)y+(1/8)y+(1/2)y =p; where y =tot life time.
y-p=8.since p=(14/16)y
we've y=64
active age=32
