Both Statements 1 & 2 alone are insufficient to answer the question and taken together they still don't offer the value for n. Hence, I chose E.II wrote:See attached problem.
Interested in seeing the different approaches in solving this question.
Thanks in advance.
II
Word Translation: To fill an order schedule, a manufacturer

What does "meet the schedule" mean from statement 2? If it means "complete the order", then I think the answer is C. If it means, get back to the rate in which is needed to complete the order, I think it's E... I think it means "complete the order", so I'd say the answer is C, which makes me hesitant because it seems to be too obvious, but here's my logic: we know from the stem that it's going to take an average rate of 1000 tools/day and we're asked for the total number or days, n, to complete the order. Because we know that they're not going to give us n directly, we need to find the work (w) for the equation: rate x time= work. Looking at the statments:mandy12 wrote:I think the answer should be B
1. ok, we're given the rate time and work for the first five days: 600 tools/day for 5 days. So, 3000 tools total. Can't do anything with that.
2. We know that to "meet the schedule" which I take to mean "complete the order", the manufacturer had to crank it up to 1,500 tools/day for the last 4 days. So, the last four days, there were 6000 tools produced. I initially thought this info would be sufficient to answer the question. However, there are a number of combinations of different rates over different periods of time that we average with the rate and work for what's given in statement 2 to get to 1000 tools/day. Because of that, there's more than one answer and 2 is insufficient.
1&2 together: If we know what it took to complete the order from statement 2, then we can plug statement 1 in to the average RTW matrix to get the total number of days, n, which is 9.
I'd love to hear other's thoughts on this one. I'm definitely overthinking it.

IMO B
here stem 2 provides us information that due to problem, last 4 days production was 1500*4=6000 units. if the schedule was 1000 units per day, even though 2 days there was no production, the target of 6 days is met by production in last 4 days.
what's tha OA?

Ans should be E as there is no way to figure out n.
It could be that first 5 days there were problem then 10 days it went smooth at 1000 per day and then last 4 days they had to catch up with 1500 per day.

(1000 * n) tools --> n days
Stmt-I
Prod. Problems:
600 tools --> 1 day
(600 * 5) = 3000 tools <-- first 5 days
what about (n-5) days? No information given on that.
Insuff
Stmt-II

Insuff
Stmt-I & Stmt-II:
First 5 days --> 3000 tools
Last 4 days --> 6000 tools
n days ---> (1000 * n) tools.
No way of determining the total number of days.
