If employees of Company X are paid $10 per hour for an 8-hour shift in a day. If the employees are paid 5/4 times this rate for time worked in excess of 8 hours during any day, how many hours did employee P work today?
(1) Employee P was paid $25 more today than yesterday.
(2) Yesterday employee P worked 8 hours.
We are asked about the hours worked today.
Statement 1) tells us he got paid 25$ more than yesterday.
The given hourly rate in the question stem is a multiple of 10, so it cannot be possible that he worked 8 hours or less it must be more.
5/4 * 10 = 12.5 for him to earn 25 more he has to work at least 10 hours.
8 * 10 = 80 + 12.5*2 = 105
However it could also be true that he worked 12 hours
80 + 50 = 130
Example: yesterday 8 hours and today 10 hours or yesterday 10 hours and today 12 hours etc..
Insufficient.
Statement 2) tells us he wokred 8 hours but we know nothing about today insufficient.
Combined we get an answer.
We know he worked for 10 hours.
Sufficient answer choice C
