Melissa is four times as old as Jim. Pat is 5 years older than Melissa. If Jim is y years old, how old is Pat?

Question: Melissa is four times as old as Jim. Pat is 5 years older than Melissa. If Jim is y years old, how old is Pat?

Solution:
Given, Jim's age = y years.
Melissa is four times as old as Jim.
So, Melissa's age = 4 × y = 4y years.
Pat is 5 years older than Melissa.
So, Pat's age = Melissa's age + 5
Pat's age = 4y + 5

∴ Pat is (4y + 5) years old.
