If A's income : B's income = 2 : 1 ; A's saving : B's saving = 4 : 1 ; can we say that -
A's expenditure : B's Expenditure = (A's income - A's saving) : (B's saving - B's income) = (2 -4):(1-1). I know there's something wrong with this concept but I have heard a method called Common factor method where we can add, subtract, multiply and divide ratios. Someone please help

Let a,b,c be complex numbers satisfying
a+b+c=abc=1
and
(ab+bc+ac)/3=1/a^2+1/b^2+1/c^2
The sum of absolute values of all possible ab+bc+ac can be written as n√m, where n and m are positive coprime integers. What is n+m?
Suppose a and b are positive integers satisfying 1≤a≤31, 1≤b≤31 such that the polynomial P(x)=x^3−ax^2+a^2b^3x+9a^2b^2 has roots r, s, and t.
Given that there exists a positive integer k such that (r+s)(s+t)(r+t)=k^2, compute the maximum possible value of ab.
