let the number of sons she has be x.

Each son has x-1 brothers.Each son has x-1 sons.

the number of sons and grand sons=x+((x*(x-1)).This is equal to the age of the woman.The age is between 50-70 is given.

x+x^2-x=p--->x^2=p------>where p is the age of the woman.

there is only one perfect square number between the number is 64.
