Bunuel - here is my understanding

Assuming total number of boxes is X
given that pam packed 0.6X boxes and stopped. Also given that Stanley packed as many number of boxes alone as he has packed with pam.

Therefore -> 0.6X + s+s = X
2s = 0.4X
s = 0.2X

boxes packed by pam/ boxes packed by stanley = 0.6x/0.4x = 3:2

boxes packed by pam/ boxes packed by stanley = 0.6x/0.4x = 3:2

Pam packed 60 boxes, while Stanley initially packed 40. Subsequently, Stanley packed an additional 40 boxes, bringing his total to 80 boxes. Therefore, the ratio of boxes packed by Pam to Stanley is 60:80, which simplifies to 3:4.

Hi All,

We're told that Pam and Stanley packed several boxes with reams of paper. While BOTH packed, Pam packed 60% of the boxes. After Pam STOPPED, Stanley packed the SAME number of boxes that he had packed while working with Pam. We're asked for the ratio of the number of boxes Pam packed to the number of boxes Stanley packed. Since this is a ratio question, it can be solved in a number of different ways, including by TESTing VALUES.

Since we're dealing with percents, it's often easy to use the number 100...

IF.... when working together, there were 100 boxes packed...
Pam packed 60% of 100 = 60 boxes
Stanley packed 100 - 60 = 40 boxes

Then Pam stopped and Stanley packed another 40 boxes, so his total becomes 40 + 40 = 80 boxes.

The final ratio of Pam's boxes to Stanley's boxes is 60:80 = 3:4

Final Answer:

GMAT assassins aren't born, they're made,

Pam and Stanley packed several boxes with reams of paper. While both packed, Pam packed 60% of the boxes. After Pam stopped, Stanley packed the same number of boxes that he had packed while working with Pam. What is the ratio of the number of boxes Pam packed to the number of boxes Stanley packed?

A. 1 to 4
B. 1 to 3
C. 3 to 5
D. 3 to 4
E. 3 to 2

Kudos for a correct solution.

We can assume that when they worked together, they packed a total of 100 boxes. Therefore, Pam packed 60 boxes, and Stanley packed 40 boxes when they worked together. After that, Stanley worked alone, and he packed another 40 boxes. Therefore, Stanley packed a total of 80 boxes, so the ratio of boxes packed by Pam to those packed by Stanley is 60 to 80, or 3 to 4.

Answer: D

My brain just went 6(P) - 4 (S) - 4 (S)
So its 6:8 = 3:4
Not to sound rude with my answer but rather recognising the pattern

This is one of those questions that drives me nuts.

It is not legit, by expressing this in terms of percent, to assume that PAM + Stanley exceed 100%.
It's a perfectly legit assumption that

60% (PAM) + 2*x % (Stanley, both with Pam and alone) = 100%

This would mean that Stanley packed 40 % of the boxes, hence PAM / Stanley = 3:2.

To get the other answer, you assume that after they reach 100% together Stanley goes for an extra 40%. That's unreasonable. I really don't get some of these questions.

The sense of the question asked here is not clear. Better question would have been:

Pam and Stanley packed several boxes with reams of paper. While packing together, Pam packed 60% of the boxes they both packed. After Pam stopped, Stanley packed the same number of boxes that he had packed while working with Pam. What is the ratio of the number of boxes Pam packed to the number of boxes Stanley packed?
