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!"
How old are the daughters?

Unless you have been to New York before, you may not be able to figure this one out. Anyway, my guess....6 4 3

Good attempt but need to explain how the ages are arrived at.

Probably in the US, they start learning piano at the age of 6?

OK, time for you to roll up your meditation mat and give your self a break. Its not fair to hold up the other's precious time. Wink

Well the ages of the daughters are 8 years, 3 years and 3 years

The approach:

1- First factor 72 in three parts.

2- Now we need to consider that one where the sum is something that is on the building.

3- As the second mathmatician got confused, that means there are two factors whose sum equal the same. They are 8*3*3 and 2*6*6. Both equal to 14.

4- Now he needed one more hint to chose one of them. So when the first mathmatician talked about the eldest daughter, that means it can be only 8*3*3, because in the other case, there is a draw.
