"I am five times as old as you were, when I was as old as you are", said a man to his son. Find out their present ages, if the sum of their ages is 64 years. Choose the correct option:
A) 47 years and 28 years.
B) 40 years and 24 years.
C) 48 years and 27 years.
D) 46 years and 26 years.
E) none of these
Let the present age of the man be ’a’ and son be ’b’,   Given, a + b = 64 or b = (64 - a)   Now the man says "I am five times as old as you were, when I was as old as you are",   So, a = 5[b - (a - b)]   We get 6a = 10b,   Substitute value for b,   6a = 10(64 - a),   Therefore a = 40, b = 24.   ANSWER:40 years and 24 years.
