I'm here in 2022, cannot afford GMAT prep classes and luckily we have channels and people like sir, who are helping people for free. God bless this channel and sir, extremely grateful for this.
The best formula to calculate the percentage is Rate = Portion / Base (R = P / B) . For the above example of what percentage of 60 is 36, R = 36 / 60 which is equal to 0.6 or 60%. I am an accountant and this formula is the best to compute without errors from my experience.
No doubt you are absolutely amazing with your shortcut methods. I am preparing for GMAT and with your teaching I don't thing I need any teaching other than this.
Sir you are amazing and inspirational, thanks for your hard work and kindling the hope for students of all genre and making it easy for all of us...great work SIr

-5 and -9 are not the factors. Those are the ways in which you have to split -14. The video, at 20:17 does not discuss factors at all. It only talks about how the middle term is split. And yes, in a subsequent step, the factors can be deduced as 5/3 and 3. Your answer about the factors is right, though.

Great video sir! I just have one little doubt. At 29:00, you divided -6+2√39 by 2, and the root came out to be -3+√39. So, how did you cancel the -6 and the 2 in 2√39 both with the same 2 in denominator?

Hi, 3 is the co-efficient of x^2. We need to multiply this with the the constant (i.e., 15) to find the product. The sum is -14 in this case. So form two numbers such that product is 45 and sum is -14. The two numbers are -9 and -5. After this solve the quadratic and find out the values of x. The values of x which you've found is spot on!

Hello Shruti Two ways to go about it. I will choose the one where we start from 1/3 and end at 33.33% Please note that it is 33.33.... % recurring decimal. To convert a fraction into percent, we multiply the fraction by 100 and compute the answer. So, 1/3 will be the equivalent of (1/3) * 100 % = 100/3% = 33.33..% The second method is a wee bit more complicated. Here's a link to one of our videos that explains the second method. czcams.com/video/XQwKE4jlQkE/video.html
Hello Riya Pls start with Getting Started Part I and then Part II. These will help get many basics in place that will find application in other topics. My suggestion is to start with arithmetic topics such as percents, fractions and then move on to algebra or geometry depending on your prowess. Keep topics such as Permutation, Probability to the end. For many test takers, these topics could be road blocks. No point starting with such topics and not seeing progress. Cheers
Hello Alex The roots are 12 and -6. However, what I have done in the table is how -6x gets split. It gets split as -12x and +6x, which when factorized and equated to zero will result in the roots being +12 and -6. I hope this clarifies your doubt. Cheers

Hi Fatema , what score did u get on gmat?
Hi Fatima what's ur GMAT score
The best formula to calculate the percentage is Rate = Portion / Base (R = P / B) . For the above example of what percentage of 60 is 36, R = 36 / 60 which is equal to 0.6 or 60%. I am an accountant and this formula is the best to compute without errors from my experience.
this formula is also helpful in clacualting profit or loss quickly

I think the result of the quadratic eq on 29:06 is wrong, it should be -6 + root39
Hello Mohammed
The answer given is correct. The roots are -3 + root 39 and -3 - root 39.
root 156 can be written as root (4 * 39) = 2 root 39
The 2 in the denominator will get cancelled with both -6 and 2 root 39 to leave us with -3 pm root 39.

Hello Joseph
Thanks for your feedback.
We have 4 videos in the getting started series. You could access them by watching this playlist - czcams.com/play/PL3JsYBL14ZltnwdqUt7NTyx9wUzVh-OZu.html
In your quadratic question my factor are 5/3 and 3 and u r saying -9,-5. Plz explain I found u all answers wrong
-5 and -9 are not the factors. Those are the ways in which you have to split -14.
The video, at 20:17 does not discuss factors at all. It only talks about how the middle term is split.
And yes, in a subsequent step, the factors can be deduced as 5/3 and 3. Your answer about the factors is right, though.
Sir solve second quadratice equation by putting values 5 and 9 as it does not give you 0

Great video sir!
I just have one little doubt.
At 29:00, you divided -6+2√39 by 2, and the root came out to be -3+√39. So, how did you cancel the -6 and the 2 in 2√39 both with the same 2 in denominator?
= (-6+2√39)/2
= 2(-3+√39)/2
= -3+√39
Thank you for this !!

At 19minutes.. 2nd example.. I am getting X=5/3 and X=3.. There is 3X square.. What will happen to 3
Hi,
3 is the co-efficient of x^2. We need to multiply this with the the constant (i.e., 15) to find the product. The sum is -14 in this case. So form two numbers such that product is 45 and sum is -14. The two numbers are -9 and -5. After this solve the quadratic and find out the values of x. The values of x which you've found is spot on!

To practice the basics what books would you recommend or should i go for?
NCERT 11th and 12th grade books just to start off, and then refer to RD Sharma, etc for tougher sums.
GMAT Prep courses will have a bit more structure as to what concepts will be tested, what sort of questions you're likely to face, etc.
Best wishes Aniket!
@@Wizako thanks! I’ll definitely follow it up!
At 20:35 second equation I think c= 45 instead of 15
Hello,
c = 15 as per the question. We have to multiply the co-efficient of x^2 with c's co-efficient. Doing so we get 45 as the product to be split.
Are we allowed to use a calculator in the GMAT
You are allowed a calculator ONLY in the Data Insights section. Not in the Quant section.
wow sir
Thanks for your feedback.
Can u pls explain how do u derive 33.33% is equal to 1/3 ?
Hello Shruti
Two ways to go about it. I will choose the one where we start from 1/3 and end at 33.33%
Please note that it is 33.33.... % recurring decimal.
To convert a fraction into percent, we multiply the fraction by 100 and compute the answer.
So, 1/3 will be the equivalent of (1/3) * 100 % = 100/3% = 33.33..%
The second method is a wee bit more complicated. Here's a link to one of our videos that explains the second method. czcams.com/video/XQwKE4jlQkE/video.html
what is the correct sequence to start with ??
Hello Riya
Pls start with Getting Started Part I and then Part II. These will help get many basics in place that will find application in other topics.
My suggestion is to start with arithmetic topics such as percents, fractions and then move on to algebra or geometry depending on your prowess.
Keep topics such as Permutation, Probability to the end. For many test takers, these topics could be road blocks. No point starting with such topics and not seeing progress.
Cheers
And after quant basics 2?
8:34 how did you solved that??? 132/17 and 49/17...???
Hi,
You will get x = 132/17 and y = 48/17 by solving the two given equations by elimination method.
@@Wizako thank you so much.. I've also asked you a question about LCM and HCF on that 1 hour video about LCM and hcf... Can u please answer that??
Where is the third part?
Hi,
There are only two videos in this series! Cheers!
time 20.36- mistake in answer x2-6x-72. Must be 12 and-6
Hello Alex
The roots are 12 and -6.
However, what I have done in the table is how -6x gets split. It gets split as -12x and +6x, which when factorized and equated to zero will result in the roots being +12 and -6.
I hope this clarifies your doubt.
Cheers
Is segment and sector are same got a little confused at 5:20
