Manhattan Review hires a graduate student to update its database of 250 questions. If one stdent updates 1 12/13 percent of all problems per week, approximately, how many students, on average, does Manhattan review have to hire to update its database of problems completely every quarter.

QA is 4

I rounded the 1 12/13 percent to 2 percent. So, 1person = 2/100 of 250= 5

from here I am lost.
Appetite for 700 and I scraped my plate!

Enginpasa1, the way u solved the problem is supposed to be extended a bit more.
Look according to the problem,
In 1 week 5 Qs are solved by 1 student
In 12 week (i.e. 3 months = 1 quarter) 250 Qs are solved by = 250 / (12 * 5) ~ 4.
So the answer should be 4. Got me, Enginpasa1?
Correct me If I am wrong


Regards,

Amitava

I see your point and this makes sens. Thank you. I like the way you put it together. The lesson learned is that it is not the math, but I need to work on understanding the question better. Being the expert, do you have any advice?
