Three in, one out (Posted on 2013-04-29) Difficulty: 2 of 5
The average age of our group of n people was 37 yrs at the end of the previous month.

This month 3 new members enrolled (aged 33, 38, and 40 yrs) and one member (aged m yrs) left.

Now the average age of our group became lower by 18 months.

Given that both m and n are square numbers, find their values.

To avoid ambiguity I SHOULD HAVE SPECIFIED:

1. ages are integers

2. no birthdays between then and now.

Now:

either

1.solve it

or

2. see Charlie's last solution
