A certain employee is paid $6 per hour for an 8-hour workday. If the employee is paid 3/2 times this rate for time worked in excess of 8 hours during a single day, how many hours did the employee work today?

(1) The employee was paid $18 more for hours worked today than for hours worked yesterday.
(2) Yesterday the employee worked 8 hours.

Kudos for a correct solution.

A certain employee is paid $6 per hour for an 8-hour workday. If the employee is paid 3/2 times this rate for time worked in excess of 8 hours during a single day, how many hours did the employee work today?

Statement 1: The employee was paid $18 more for hours worked today than for hours worked yesterday
We don't know the number of hours employee worked yesterday -- Insufficient

Statement 2: Yesterday the employee worked 8 hours
We don't know the relationship between yesterday & today -- Insufficient

Combining 1&2:
6*8 + 6*(3/2)*x = 6*8 + 18
x = 2
Two statements together are sufficient, Answer C

Synthesizing the question 6$/hr normal and 9$/hr for overtime paid after 8hrs of work in a day.

Looking at (1) employee got 18$ which could mean that employee worked for 5 hours today and 2 hours yesterday or 2 hours additional overtime etc. Hence N.S

Looking at (2) employee worked for 8 hrs hence no overtime however nothing about how many hours we worked today so N.S.

Combining both since the employee worked 8 hrs yesterday today to get 18$ more he or she worked overtime for 2 hrs. Hence Answer is C.

Normal hours - $6/hr. Overtime - 3/2*6 = $9/hr

St-1, $18 more than yesterday. --> If overtime it is two hours (18/9) more than yesterday. If normal time it is three hours (18/6) more than yesterday. Still no of hours for the day is not available. So not sufficient

St-2, only yesterday's hours are available. Full normal time hours - 8. Clearly not sufficient.

Combining 1 + 2, extra hours will be overtime so 2 hours more than yesterday. Sufficient

Ans - C

1: We don't know the hours worked on yesterday - Not sufficient
2: We need to find out the hours worked on today not yesterday - Not sufficient

combine both: Hours worked yesterday: 8 hours(48$) Total salary today is 48+18 = $66 from this we can find the hours worked

ANS C

Ans C

To solve such a question, we need atleast 2 of the following:

1. rate
2. time
3. total= rate x time

From Stem, we have 1, ie. rate.

Stmt 1: from the given rate, either he worked 3 extra regular hours or 2 over time to make 18 bucks more. NS
Stmt 2: time he worked yesterday doesnt say how many hours worked today-- NS

combined together:
if worked 8 hours yesterday, to make 18 dollars today-- he worked 2 hrs over time. ie. total of 10hrs. Sufficient.

Ans: C
