Answer:
12 years old
Step-by-step explanation:
STEP 1: Find their total age
Average age of man and son = 30
Total age of man and son = 30 x 2
Total age of man and son = 60
STEP 2: Define x
Let the son be x years old
The man will be 4x
STEP 3: Find their total age in term of x
Total age = x + 4x
Total age = 5x
STEP 4: Solve x
5x = 60
x = 12
STEP 5: Find the son's age
Son = x
Son = 12 years old
Answer: The son is 12 years old
