In a certain factory, hours worked by each employee in excess of 40 hours per week are overtime hours and are paid for at $$1\frac{1}{2}$$ times the employee’s regular hourly pay rate. If an employee worked a total of 42 hours last week, how much was the employee’s gross pay for the hours worked last week?

(1) The employee’s gross pay for overtime hours worked last week was $30. (2) The employee’s gross pay for all hours worked last week was$30 more than for the previous week

Option A.
The gross pay for the overtime hours is $30. He worked for two hours overtime at 1.5 rate. Thus he worked worth 3 hours of normal pay. 3 hours of normal pay =$30 --> 1 hour of normal pay = $10 Option B. Earned$30 more than previous week. Incase he worked overtime even the previous week, we cannot determine the overtime hours and hence the normal rate.

Therfore A alone is sufficient.

Hope this helps.

Suppose regular pay is $x per hour. For last week: Gross pay of employee: 40x+2*(1.5x) = 43x. Statement 1 Overtime payment is$30.
3x = 30.
x is known
Gross pay for the week is known.
Statement (1) is sufficient.

Statement 2
No data about what employee got in the week before last is available. Not Sufficient.
