don't forget
1 1 and 11
so your interpretation (which i don't agree with) of the last clue doesn't help distinguish between 1,1, and 11 and 2,2, and 9
All the clues are important when the question is structured correctly. This version of the question makes it more clear:
two MIT math grads bump into each other at Fairway on the upper west side. they haven't seen each other in over 20 years.
the first grad says to the second: "how have you been?"
second: "great! i got married and i have three daughters now"
first: "really? how old are they?"
second: "well, the product of their ages is 72, and the sum of their ages is the same as the number on that building over there.."
first: "right, ok.. oh wait.. hmm, i still don't know"
second: "oh sorry, the oldest one just started to play the piano"
first: "wonderful! my oldest is the same age!"
