Mr. Brown 18 years older than his son.​

Question

Mr. Brown 18 years older than his son. Their total age is 60 years. Calculate Mr. Brown's age and his son's age ?​

Answer 1

B= S+18

B+S = 60

S+18 + S = 60

2S = 60-18 = 42

S = 42/2 = 21 years old for the son

B = 21+18 = 39 years old for Mr. Brown

39+21 = 60
