Answer: Leo is 24 years old,
Step-by-step explanation:
Let 'x' denotes the age of Mark.
Given , Leo is three times older than Mark.
i.e. Expression for Leo's age = [tex]3x[/tex]
Since , sum of their age is 32, then
[tex]x+3x=32\\\\\Rightarrow\ 4x=32[/tex]
Now , divide both sides by 4 to get the value of x.
[tex]x=\dfrac{32}{4}\Rightarrow x=8[/tex]
Thus , Age of Mark = 8 years
Age of Leo = 3 (8) = 24 years
Therefore , Leo is 24 years old.
