Suppose that 40 women and 76 men are in a room and each of the women knows exactly M of the men and each of the men knows exactly W of the women where both M and W are greater than 1. (Assume that if a woman knows a man that man must know that woman and vice versa.) What is the smallest possible ...

If the proper divisors of the number are defined as the number of divisors except 1 and the number itself ( for example proper divisors of 12 are 2, 3, 4 and 6, but not 1 and 12), find how many numbers are possible whose biggest proper divisor is 29 times as big as the smallest proper diviso...
