Answer 1

Answer:

Tina is 20 years old.

Step-by-step explanation:

Mattew is 66 years old. and 3 times older than his daughter Ann.

Let age of tina be x

Ann is two years older than her sister Tina

age of Ann = 2+x

Mattew is 66 years old and three times older than his daughter Ann

Age of Mattew = 3 × Age of Ann

66 = 3 × (2+x)

66 = 3 ×2 + 3 × x

66 = 6 + 3x

66 - 6 = 3x

60 = 3x

or, x = 60/3

x= 20

Tina is 20 years old.
