Answer 17

Fraction of life as a boy = 1/4
Fraction of life as a youth = 1/8
Fraction of life as an active man = 1/2
Fraction of life as boy, youth and active man = 1/4 + 1/8 + 1/2 = (2 + 1 + 4)/8 = 7/8
Fraction of life as an old man = 1 − 7/8 = 1/8
Thus, one-eighth of Man Wrinkle's life (as an old man) is 10 years.
So, Man Wrinkle's Age = 80 years.

Answer 18

Fraction of life as a boy = 1/4
Fraction of life as a youth = 1/8
Fraction of life as an active man = 1/2
Fraction of life as boy, youth and active man = 1/4 + 1/8 + 1/2 = (2 + 1 + 4)/8 = 7/8
Fraction of life as an old man = 1 − 7/8 = 1/8
Thus, one-eighth of Man Wrinkle's life (as an old man) is 12 years.
So, Man Wrinkle's Age = 96 years.

It may be noted that:
Life as boy = 96/4 = 24 years.
Life as youth = 96/8 = 12 years.
Life as active man = 96/2 = 48 years.
Life as old man = 96/8 = 12 years.

The problem may also be solved by setting up the following equation: a/4 + a/8 + a/2 + 12 = a
where a denotes Man Wrinkle's age in years.
The equation may be solved as shown below.
7a/8 + 12 = a
12 = a − 7a/8 = a/8
a/8 = 12 or a = 96.

Therefore, life spent as active man = 96/2 = 48 years.

Answer 21

type in 80. it's wrong than type in 48 its right

Answer 22

The problem may also be solved by setting up the following equation: a/4 + a/8 + a/2 + 11 = a
where a denotes Man Wrinkle’s age in years.
The equation may be solved as shown below.
7a/8 + 11 = a
11 = a − 7a/8 = a/8
a/8 = 11 or a = 88.

Therefore, life spent as active man = 88/2 = 44 years.
