At a certain company, employees who earn $20.00 per hour will be given an increase of $1.00 per hour. For each of the other employees, either the employee will be given an increase of $1.00 per hour or the employee will be given a percent increase equal to the percent increase that will be given to the employees who earn $20.00 per hour, whichever results in a larger increase for that employee. Which of the following statements are true?
I. An employee who earns less than $20.00 per hour will be given a percent increase that is greater than the percent increase that will be given to the employees who earn $20.00 per hour.
II. An employee who earns $22.00 per hour will be given an increase of $1.10 per hour.
III. An employee who earns $24.00 per hour will earn $25.20 per hour after the increase.
A. I only
B. II only

This tells us three things
(a) that <20.00$ will lead to an increase of $1.00
(b) that >$20.00 will lead to a percent increase equal to 100*1/20 or 5%
(c) that =20.00$ will lead to an increase of $1.00
Now we are looking at MUST be true question
I. An employee who earns less than $20.00 per hour will be given a percent increase that is greater than the percent increase that will be given to the employees who earn $20.00 per hour.
1 will be a greater percentage of <20.00 that for 20.00.
On an amount of 20, 1 gives 5%, but for an amount 10, it will be 100*1/10=10%, so on amounts less than 20, it will always be >5%.
True
II. An employee who earns $22.00 per hour will be given an increase of $1.10 per hour.
The employee will get a 5% increase, so increase =22*5/100=1.1$
True
III. An employee who earns $24.00 per hour will earn $25.20 per hour after the increase.
The employee will get a 5% increase, so amount=24+24*5/100=24+1.2$=25.20$
True
All three true

The hidden clue in this question is the percentage increase in salary given to the persons earning $20/hr. If you are someone who earns $20/hr and you receive a $1/hr raise, you received a 5% increase, right?
You will now see that interpreting the second statement of the question becomes very simple. But before that, let’s break up the persons into three categories:
Category 1 – People who earn $20/hr. These people receive a $1/hr (or a 5% raise).
Category 2 – People who earn <$20/hr. 5% of a number less than 20 is less than $1. Therefore, these people receive a $1/hr increase which represents more than 5% of their salary.
Category 3 – People who earn >$20/hr. 5% of a number more than 20 is more than $1. Therefore, these people receive an amount equal to 5% of their salary since this will be more than $1.
Now that this is clear, let’s evaluate the statements one by one.
Statement I says that people in category 2 earn a higher percentage increase than people in category 1. From the above discussion, we know that this is true. Statement I has to be a part of the answer, so answer options B and C can be eliminated.
Statement II and III talk about two individuals who are in category 3. It’s clear that these individuals will receive a 5% increase on their respective salaries.
5% of 22 is 1.10 and 5% of 24 is 1.20. Clearly, statement II is true. When 1.20 is added to 24, the result is 25.20. Statement III is also true. Answer options A and D can be eliminated.
The correct answer option is E.
Hope that helps!
