Can anyone help me solve this ?

What is the largest value of n such that (20!X20!)/ 40^n is an integer ?

This question is discussed here: https://gmatclub.com/forum/if-20-20-20- ... 17502.html

Hope it helps.

Thanks Bunuel.

Hi @Bunuel, if you see this one is a bit different from the one explained and that is why I asked. I need to decide which of the two is a limiting factor 2^3n or 5^n ?

The one you sent is deciding between 2^2n and 5^n where 5^n wins.

the answer is n = 8
20! has 18 "2" and 4 "5" since we have two 20!, we have 36 "2" and 8 "5" = 2^36 and 5^8
taking 2 as determinating factor, 3n = 36 -> n = 12

taking 5 has determinating factor, n = 8

thus the smallest is n = 8 for factor 5

My bad, I thought you meant official test (not recommended w/risk of being banned if it’s not official)

If i do complete gmat test after completing al sections test i.e. 33 Quant, 14 Vebral and 14 DI. Will there be new questions in the complete GMAT test or the old ones only which are already answered in sectional test ?

No, questions will never repeat unless you reset the question bank. You’ll just have zero test left.

i tried paying it feels like a scam, checkout reddit before paying

Hello everyone ! Here is today’s (May 5) DI Butler Question: company-x-our-company-s-computer-technology-is-out-of-date-we-will-b-444783.html#p3565601

Data related to the past 30 years reveals some interesting insights about the propensity of a country to go into a war. Over the past 30 years, the countries that maintained the highest military strengths were also more aggressively involved in a higher number of wars. Moreover, the likelihood of getting aggressively involved in a war increased for countries whose military strength increased significantly during this period. Since there was no major world-wide war phenomenon in the recent past, it is likely that an increased military strength causes the increase in aggressive behavior and the higher involvement in wars.

Which of the following, if true, most strengthens the argument?

A. The data doesn’t distinguish between the countries that were consistently involved in war and the countries that were involved in more wars during the beginning and end of the 30-year period.

B. Some countries cited in the data were rarely involved in any war

C. Data shows that none of the countries that had zero increase in military strength showed any increase in their involvement in wars.

D. Situations that trigger an increase in military strength such as political tensions with neighboring countries are also likely to increase a country’s propensity to become involved in wars.

E. Data related to some of these countries is available only for a partial duration out of the 30-year period

In this question, shouldn’t the answer be D

Answer seems to be D, which rather weakens.

IMO it’s C : Showing that if Cause is not there then effect is also not there

yes agreed. I think i saw the answer wrong its C.

Is the answer d ?
