to find the employee paid last week
- we need to know how much hours he has worked on each day,overttime,
- what are his hourly rates

stmt1
gives the rate but no idea how much he has worked

stmt2
employee has worked 54-40=14 hours more. since has not worked more than 8 hours per day, can either divide 54 in (8,8,8,8,8,8,6) or (6,8,8,8,8,8,8)
stmt is not suff because
- we do not know the wages per hour
- there are many combination possible for hours worked. if on sunday he works 8 or 6 hours, then the wage wil change

both stmt1 and stmt2
not enough

I'm in the same boat re: DS. I really think practice is the only way to get these down perfectly.

In the case of this question, there are a lot of interesting variables, and GMAT wants to make sure you're paying attention.

You know that regular overtime = 1.5r * (t - 40), where r is regular hourly rate and t is total hours. You are also told the employee gets a special Sunday overtime = 2r * (S) where S equals hours worked on Sunday.

The final question is: how much was the employee paid last week? Meaning we need variables r, t, and s.

1) This provides r, but not t or S. INSUF
2) This provides t but not S. INSUF

Without a clear explanation of what portion of t was hours worked on Sunday, we can't solve for Sunday overtime. Therefore, 1 and 2 are INSUF together.

We learn through Practice.

Keep working on DS, few of the questions are tricky; you just have to avoid capturing yourself in DS Trap.

Anyways; E for the above question...

An employee is paid 1.5 times the regular hourly rate
for each hour worked in excess of 40 hours per week,
excluding Sunday, and 2 times the regular hourly rate
for each hour worked on Sunday. How much was the
employee paid last week?

(1) The employee’s regular hourly rate is \$10.
(2) Last week the employee worked a total of
54 hours but did not work more than 8 hours
on any day.

I have a doubt when you combine both statments. please can some clarify.

C is sufficient
Total pay = 10*40 + 1.5*10*8+ 2 * 10 * 6

But I think there is a trap since we don't know how many hrs he worked on Sat. So the pay will change. Hence the answer may be E

The answer is E, as the break-up for the weekdays and Saturday + Sunday is not known.

It could be 5 * 8 + 6 (Sat) + 8 (Sun)

It could be 5 * 8 + 7 (Sat) + 7 (Sun)

Thanks ..subhash ....thinking about it late in the evening that

54-40 = 14 hours. These 14 could be worked like 8+6 or 6+8 or any other combination.

I think the answer is E. You can't know how many hours he worked on Saturday or Sunday.

Because we don't know exact Saturday/Sunday hours.

An employee is paid 1.5 times the regular hourly rate for each hour worked in excess of 40 hours per week, excluding Sunday, and 2 times the regular hourly rate for each hour worked on Sunday. How much was the employee paid last week?

(1) The employee's regular hourly rate is \$10. No information about the number of hours the employee worked last week and what was the distribution of these hours. Not sufficient.

(2) Last week the employee worked a total of 54 hours but did not work more than 8 hours on any day. We don't know what is the regular hourly rate and the distribution of these 54 hours. Not sufficient.

(1)+(2) If the employee worked 40 hours from Monday to Friday (8 hours per day), 7 hours on Saturday and 7 hours on Sunday, then the employee was paid 40*10+7*15+7*20. But if the employee worked 40 hours from Monday to Friday (8 hours per day), 8 hours on Saturday and 6 hours on Sunday, then the employee was paid 40*10+8*15+6*20. Not sufficient.
