Answer:

Age of Mark

Explanation:

Let age of Mark be
years.

Mark's dad is three times older than Mark

Age of her Mark's dad
=3x

Mark's sister is 2 years younger than Mark

Age of Mark's sister
=(x-2) years

The sum of their ages is 48.

$x+3x+x-2=48\\5x-2=48\\5x=50\\x=10$

Age of Mark
=x=10 years

Age of Mark's dad
=3x=3(10)=30 years

Age of Mark's sister
=x-2=10-2=8 years
