[quote="Bunuel"]What is the average (arithmetic mean) monthly salary of a worker at Company A?

(2) At Company A, the total amount spent per month on salaries of men is one-half of the total amount spent per month on salaries.
The question asks about the average salary per worker. We can solve this in two ways : 1.if we’re given the ratio of men to women and we know the respective average salary of both men and women then we can solve for the average salary . 2
The other method is if we know the total salary of workers in the company and the total number of workers then we can solve for the average salary per worker. Let’s go to the statements
St 1 : we only have total salaries of workers not sufficient
St2 : we only know the ratio of salaries of men to women not sufficient
1+2 : still insufficient because we don’t know anything about the total number of men and women or we don’t also know the ratio of men to women in the company
Hope it’s clear 👍
