The provided text contains solutions to two distinct questions. Question 8 involves logical deduction based on descriptive attributes of individuals. Question 9 involves solving an algebraic equation

Let Bako's current age be $B$.
Five years ago, Bako's age was $B-5$.
The problem states Bako is twice as old as he was five years ago:

Bako's current age is 10 years.

The mother is now 35 years old.
Five years ago, Bako was $10-5=5$ years old.
Five years ago, the mother was $35-5=30$ years old.
The problem states the mother was six times as old as Bako five years ago:

This is consistent.

a) How old is Bako?
Bako's current age is 10 years.
The answer is $\boxed{\text{10 years old}}$.

b) How old was his mother when Bako was five?
Bako is currently 10 years old. He was five years old $10-5=5$ years ago.
His mother's current age is 35. So, 5 years ago, his mother was $35-5=30$ years old.
The answer is $\boxed{\text{30 years old}}$.

c) How old will Bako be when his mother is 50?
His mother is currently 35 years old. She will be 50 in $50-35=15$ years.
Bako is currently 10 years old. In 15 years, Bako will be $10+15=25$ years old.
The answer is $\boxed{\text{25 years old}}$.

d) How old was Bako's mother when he was born?
Bako is currently 10 years old. He was born 10 years ago.
His mother is currently 35 years old. So, 10 years ago, his mother was $35-10=25$ years old.
The answer is $\boxed{\text{25 years old}}$.

e) What is the difference between Bako's age and his mother's?
Mother's current age is 35 years. Bako's current age is 10 years.
The difference is $35-10=25$ years.
The answer is $\boxed{\text{25 years}}$.
