Minh is 16. His parents are both the same

age. The three of them have lived a total

of 100 years. How old are his parents?

The parents age 42 years old

Explanation:

Let the age of Minh's father be x years

Given, his mother is of same age as of his father

Then, his mother's age is x years

According to question,

Minh's age + His father + His mother = 100

16 + x + x = 100

16 + 2x = 100

2x = 84

x = 42

Therefore, both, minh's father and his mother is 42 years old

His parents are 42.
