A professor tells her assistant that she dined with three people last night. She also tells him that the sum of the three people's ages is twice the secretary's own age and that the product of the three people's ages is 2,450. Then, she asks him to tell her the ages of the three people. After a while, the assistant tells the professor that he doesn't have enough information to solve the problem. She agrees and adds that she is older than all three people with whom she dined. The assistant, who knows her age, promptly gives the professor the correct ages. The question is: What are the ages of all five people in this story?

The professor dined with her husband and kids, aged 35, 10 and 7. The assistant is 26.
I'm not sure if it's possible to say exactly how old the professor is, but definitely over 35. 36 maybe?

The assisstant is older then the 3 people the professor dined with, therefore husband cant be 35 whilst assisstant is 26.

It states in the question that the proffesor says she is older than all she dined with (ie...she...the woman...herself)
Looks like another case of misleading questions, poor grammar.

The professor is a woman, the assistant's gender is never stated. Hope that helps.

A jail consists of 100 cells in a line, all starting out closed. The warden gets drunk one night and goes along opening every single cell. He then returns to the beginning, and "toggles" every second cell -- in this case, they're all open, so he closes every other cell door. He then runs to the beginning again, and "toggles" every third cell, then again with every fourth cell, and so on until the very last run in which he only toggles the hundredth cell, then drops down from exhaustion.
How many cells are left open after this process?

Its 10. Every square number will be left open, because only square numbers have an odd amount of factors.

No...FFS
If hes gone and toggle in factors of 2 then 3 then 4 then 5 then 6 then 7 then 8 then 9 then 10 then 11 then 12 then 13 then 14 then 15....so on son on..he would have toggled every bloody door out of default, apart from the first...

Look, I don't write these riddles, I only copy+paste them. Call it plagiarism. BTW it was ten, and the other riddle, I can't remember.

Maybe you just don't understand English Norse, because I understood it fine.
