The ages of the brothers

Alberto, Benito and Carlos are three very intelligent brothers. One day the following conversation occurs between them:

  • Carlos: - Have you noticed Benito that I am three years older than you?
  • Benito: -Yes, I had noticed. But have you taken into account that in two years you will be twice as old as Alberto will be?
  • Alberto: -Dear brothers, if someone listens to our conversations, I could easily deduce how old we are! The only data that would be missing is that I have one year more than Benito.
  • Carlos: Ha ha, it's true. How smart we are!

What is the age of each of the three brothers?

Solution

Benito is 4 years old, Alberto 5 and Carlos 12.
