Answer:

Sam is 10 years old.

Explanation:

Lets just say this was asked in 2020 meaning 5 years ago was 2015.

If Pete was 15 in 2015 and his age was 3x the age of Sam, Sam would be 5.

15/3= 5

Now that 5 years has passed since 2015 Sam is 10 and Pete is 20.

(15+5) + (5+5)

Adding the two ages in current times, the sum is 30.

20 + 10 = 30
