Question 24
Mrs Tan and Mrs Ong were having a conversation at a park.
Mrs Tan: “Hi, how are you? How are your children? You have three if I remembered correctly. How old are they now?”
Mrs Ong: “Yes, I have three children. The product of their ages is equal to 96. The sum of their ages is equal to the number of trees in this park.”
Mrs Tan counted the number of trees in the park, thought for a while and said,
“I still could not figure out the ages of your children.”
Mrs Ong simultaneously replied,
“Pardon me, for I have to pick up my children from the school across the park. We can catch up again soon. Goodbye.”
Finally, Mrs Tan managed to figure out all the ages of Mrs Ong’s children. How old is Mrs Ong’s youngest child?
Source note: the intended deduction uses positive whole-number ages and an unstated interpretation of which children are old enough to attend the school.
