Title: Guess the age
Xiao Ming took two younger sisters to the Lantern Festival. When someone asked them how old they were, they said mischievously: "The product of our two ages is 6 times the sum of our ages." Xiao Ming added: "They are not twins, and the difference in age must be no more than 8 years old."
