Ryan works in an office that has an even number of men and women working there. Ryan participates in a meeting composed of 4 men and 6 women who are pulled from the office floor.  This reduces the number of women working on the office floor by 20%. How many people work at Ryan's office? Think carefully first, then make a decision:
Since 6 women are 20% of the total number of women working there, that means there are 6 * 5 = 30 women working there in total. Since there are an even number of women and men working in the office, that means there are 30 * 2 = 60 people working there in total, since there are 2 sexes. So, the answer is 60.
