Can you please make more videos on permutations and combinations.. the differences and how to distinguish the problems with respect to which concept would be used in which case

@Ephesians3-3412 7 ай бұрын

Questions that include words like, "arrangement," "display," "rank," or "order" are indicative of a permutation's question. Problems that ask about the number of ways you can combine, or create subgroups signal a combination's question.

Hey there! Would love to see a video of the strategies to tackle the hardest GMAT Algebra questions.

@devondevon4366 2 жыл бұрын

9:22 Since the expression a/b + 1 can be expressed as (a+b)/c and since each unknown is one of the numbers 2, 3, or 5, you want the ----------- c/b denominator to be the smallest (2)of the three integers, hence (3 + 5)/2 = 4 . Hence the greatest possible value o expression is 4, answer

Hey Erika, Would you recommend us to solve the last problem during the GMAT at all -considering it took almost 3 mins to do it mentally?

@erikatyler-john2005 3 жыл бұрын

This is a great question, Atharva! Honestly... it depends. If you're not sure how to approach the problem after ~30 seconds and you're slammed for time, this would be a great candidate to guess on. But if you've got the approach figured out and you're on target for time, it's reasonable for some Quant problems to take ~3 minutes! I typically think about Quant problems as taking between 1 and 3 minutes, with the shorter ones balancing out the longer ones to give 2 minutes per question on average. This would be one of the longer ones for sure. That said, I wouldn't take more than 3 minutes on a Quant problem - it just isn't worth it.

1:15 angle E =45 since angle DAE =40 (parallel line and transversal) given that angle C from ACB =40 (75+65+40=180) hence 180- (40+95)=45 degree answer

15:45 , B cant be 5 since A would have to be a unit digit that when multiplied by 5 = 3, but 5 times any number ends in either 0 or 5, hence A =5 has to be ruled out hence A =6

@nicoleweigelt3938 Жыл бұрын

In general it cant be 5 because there is already a 5 under the line

Question that starts after 12:14: How can one assume it's B*B that resulted in 4 digit number, even if it was giving other product something to carry, the 4 digit number might be because of B*A.

@MagooshGMAT Жыл бұрын

In this case the only number we ruled out due to that issue was 1, and that's because it is not possibly to multiply a 3-digit number by 1 and get a 4-digit result. For example, 311 * 1 = 311. That will always be the case, and no numbers will carry over since the highest number, 9, multiplied by 1 is still 9. You won't get a result big enough that it needs carried. Hope that helps!

@DropshippersNightmare 11 ай бұрын

For the hard arithmetics problem isn't B surely 6? I crossed out 5 because it was a known value in the answer (CB5B) where it would just be shown as B instead of 5. I am new to GMAT, so please correct me if I'm wrong. Thanks!

13:17 answer 17 A A B x B ----------- C B 5 B Only 1x1, 5x5, 6x6 will give you the same digit B B B 1 can be ruled out since 1 would give AAB (and not four digits CB5B), 5 can be also ruled out since 5 x a number 'n' would have to equal 3 (but 5 times a number 'n' equals 0 or 5). Hence B is 6. Need A to be number when multiplied by B (which is 6) will give 2 (either 6x7 or 2x 6). A is 7 hence 7 7 6 x 6- = 4 6 5 6 Hence A+B+C = 17 answer

The question starting at 12:22. Is it a confirmed 700 question? It seems to me as if it takes like very much time to come up with the right solution

Hi Itachi, yes, this is a Very Hard question, and our Very Hard questions tend to fall within the 700+ range.

Hi, Erika. My answer to the last question is 15. The solution is B=6, A=2, and C=1 (total sum of 15). It's different from the answer you got.

The Quant section tests different concepts, try taking a diagnostic quiz or test to get a better sense! We have a free diagnostic on our GMAT blog.

@sajidibnhasan5652 Жыл бұрын

Sorry, But I did not understand that why the number 5 and 6 was choosen and then only 6 for the B

@MagooshGMAT Жыл бұрын

Hi Sajid! Erika showed us that for the problem we had BxB= a number that ends in B. So, she was going through the options quickly to show which ones would give us that result. Since 5x5=25, that is one option (25 ends in 5). And since 6x6=36, that is another option (36 ends in 6). Then, Erika began by plugging the 5 in for B in the problem. However, when she saw that 5A would have to equal a number that ends in 3, she could tell it wouldn't work out because no integer multiplied by 5 ends in 3. So, that's how she determined B = 6. Hope this helps a bit! Happy studying to you! :D
