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?

Indicate all such statements.

A. 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.
B. An employee who earns $22.00 per hour will be given an increase of $1.10 per hour.
C. An employee who earns $24.00 per hour will earn $25.20 per hour after the increase.

A. 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.
B. An employee who earns $22.00 per hour will be given an increase of $1.10 per hour.
C. An employee who earns $24.00 per hour will earn $25.20 per hour after the increase.

[Reveal] Spoiler:
A is correct. $1 is 5% of $20. If an employee makes less than $20.00 an hour (e.g. $19 dollars an hour), a $1 increase is 5.26%, which is greater than 5%.

B is correct. 5% of $22.00 is $1.10 per hour.

C is correct. 5% of $24.00 is $1.20. $24.00 + $1.20 = $25.20 per hour.

How can we find out in such questions the percent increase? like here it is taken as 5% of 20. So how can we assume that?

GIVEN: 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?

Are you referring to Statement A?

A. 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.

If someone presently earns $20 per hour, a $1 increase represents a 5% increase.
Percent increase = 100(new - old)/old
Since the new wage is $21 per hour, the percent increase = 100(21-20)/20 = 100/20 = 5 (percent)


Let's see what happens if someone presently earns $18 per hour
This person's new age will be $19/hour
In this case, the percent increase = 100(19-18)/18 =100/18 ≈ 5.56 (percent)

Does that help?

yes Brent, I was confused in statement A, it was difficult to comprehend. I understood it now. You made it very simple as usual. Thanks :)
