Challenge: The Robinson Family

Mr. and Mrs. Robinson were considering University of Toronto Schools for their three children.

  • "How old are your children?", asked Ms Jean Brodie, the Principal.
  • "You should be able to work it out", came the reply. "The product of their ages is 36 and the sum of the ages is the same as the number in our street address."
  • "That is not enough information", replied Ms Brodie after a pause; "Can you tell me more?".
  • The oldest looks just like me", said Mrs. Robinson.
  • "Well, now, I can tell their ages", announced Ms. Brodie.
