My Son is Naughty
Jack and Ray were at the rugby. Ray’s team was winning 
so Jack decided to give Ray a problem to deflate his ego a 
bit. So Jack said “Did you know that today is my three 
sons’ birthday?” “How old are they?” Ray asked taking 
the bite. “I’ll give you a hint. The product of their ages is 
36 and the sum of their ages is 13,” Jack replied. “That’s 
no help,” said Ray. So Jack weakened and gave him 
another clue. “O.K. My youngest son is very naughty.”
“Nothing to it,” exclaimed Ray and he told Jack the 
correct ages of his sons. 
How did Ray figure out the correct answer and what are 
Jack’s sons’ ages?

We made a movie to explain our ANSWER.
