This question is misleading and designed for you not to get the answer because it's leading you to believe that the answer should be a percentage. when it should ask for the total of employees that attend night school.

Why do I see this answer and 25%?!? Its not a total number but a % of all employees. Tell me if Im wrong so I dont bother taking the test. Thanks.

n= number of night school attendees t = total employees m=number of male employees w=number of female employees Four variables but only three equations (seen below). Answer is in terms of two of the variables, so only three equations needed to solve. Solution: n/t = fraction (percentage) of total employees attending night school Relevant equations: .4t=m (40% of employees are men) m+w=t (all men + all women = total number of employees) n=.3m+.2w (30% of men + 20% of women = employees attending night school) n/t = [.3m+.2w]/t = [(.3m+.2*(t-m)]/t = [.3m+.2t-.2m]/t = [.1m +.2t]/t = [.1*.4t-+2t]/t = [.04t+.2t]/t = .24 n/t = 24%

If you assume 100 employees: 40% of men = 40 men 30% of that 40 men = 12 men Therefore, there are 60 women employees 20% of 60 women = 12 women 24 people attend the night school 24 is N% of 100 24/100 x N/100 = 24% Answer: 24% of all employees attend the night school

This can be done without a calculator. If you assume 100 total employees, 40 are men and 60 are women. 30% of the men would make up 12 men. 20% of women would also make up 12 women. 12+12=24.

24 This is from their test sample sheet of the algebra word problems to be done without a calculator.
