karilla on kolme lasta, joiden ikien tulo on 455 karilla on kolme lasta, joiden ikien tulo on 455. Minkä ikäisiä lapset ovat? Leila on 23-vuotias ja hänellä on 3 nuorempaa sisarusta, joiden ikien tulo on 132. Minkä ikäisiä Leilan sisarukset ovat? (Esitä kaikki ratkaisut) My translation into English is: on the rocks there are three children the product of their ages is 455. How old are the children? Leila is 23 years old and she has 3 younger sisters the product of their ages is 132. How old are Leila's siblings? (Present all the solutions). I'm convinced that my translation is incorrect because mathematically I cannot solve the first question. So I wish some Fin would pop over here and help me with a correct translation. Thanks

The first translation is indeed incorrect, but not for the reason you would assume. The word "Kari" which means a rock at sea is also a common man's name in Finland. So the translation would be "Kari has 3 children, the product of whose ages is 455. How old are the children!" The mathematical problem is indeed a little hard, but not impossible. A possible example is 5x7x13. (I divided 455 by 5 since it could very well be a factor, and considered what numbers would make up 91, which is needed to get 455 from 5.) I hope this helps!
