103 life saving minutes spent on an eye-opening session. Sessions like these are life saving. Billion Thanks to GMATclub and Aditya.
This dude is the GOAT - 3 kings of GMAT are Charles GMAT NINJA, Aditya Kumar, and Scott Woodbury TTP
Can you pls suggest some videos to go through
I can't believe how much time I've wasted on inequality questions trying to plug in values. This is literally the most helpful video I've come across in all my prep. Thanks so much!!!
This was legendary. Great efforts put in by the tutor with good examples. Hats off!
Thank you for your feedback - keep it coming! Glad you found this session helpful! We have more going on every week on Tue and Friday! Make sure to subscribe to get notifications about new GMAT lessons taught by some of the best GMAT Instructors here on TH-cam.
I wasted a lot of time before I found this. I am from non-mathematical background so this video came as a saviour! Thanks a lot GMAT CLUB and Aditya.
Glad it helped! Thanks!
The best webinar I have attended on inequalities. Thank you so much :)
What an amazing session. I think GMAT club needs to have more such sessions with Aditya Sir instead of the other sessions which are more marketing and don't add value
Thank you for starting this channel and providing us with helpful insight on how to tackle the GMAT
Our pleasure! Stay Subscribed.
Aditya: Thanks, thanks, thanks! The best explanation on inequalities I have seen!
I never believed the number line could be this powerful.
Gosh!
@aditya, I had gone through lots of videos to understand inequalities, and quadratic expression on inequalities. they way you taught was very effective than all. I appreciate your effort.
I would highly appreciate more of your contents Sir. Loved your teaching process. thank you so much
Awesome Video... I think nobody will explain better than this. Thanks Aditya Sir
Excellent session Aditya ji. Thoroughly enjoyed revisiting these strategies. Your teaching style suits me !
This was good.. will try and apply the concepts on questions and then see how useful it is
Wonderful insights covered here. Thanks!
Such calming way of explaining this complex topic, loved it!
Thank you so much for sharing this video -- Very informative and helpful.
Great explanations. Thank you
1:26:52
On question no 4, we arrived at (x-y)^2 >2xy after factorizing x^2 +y^2 "some positive number" and solved the problem and hence arrived at the answer the option is not sufficient.
But if we take the positive number itself which is (x-y)^2 and try to evaluate it. (x-y)^2 as it is positive, we can say that (x-y)^2 >0 which can be written as x-y>0 and hence x>y, thus making the condition sufficient. Can someone help me understand why my understanding is incorrect?
GREAT..!!! One of the best..!!!
For the first time, I liked a crack verbal video. Well done Aditya Kumar!
Ha ha. Yes I agree. All their videos are just marketing gimmicks
one word. Lifesaver!
Thank you!!! This helped me a lot!
what a teacher, thanks a lot
trust me ik all this but forgot with the time and now i feel good as ever. thank you so much for teaching just like my inter college maths sir

Brilliant lecture on inequalities! Thank you!
The sessions conducted by you are very helpful and interesting, thank you.
Hey Aditya Sir, great session. Please take more sessions on other GMAT topics :)
why does the max min method work for trying to find the range of a square? somehow zero doesn't show up as a value in the second question for y^2
Thank you so much for this video. I have a doubt. At 54:38 , could you please explain how 1/16 is the biggest value. Because if you move right on the number line, there's -1/3 , -1/2 , -1/1. And the square of all of them will be greater than 1/16.
Also how is -1/32 smaller than -1/144?
Plot the number line correctly. -1/3 (which is essentially -0.33) is smaller than -1/4 (-0.25) and is beyond the stated minimum value of y.
quick question with the last Q
can we stop at (2+x) (3+x) - (2+y) (3+y)/(3+y)(3+x) > 0 and infer that for this statement to be true we need (2+x) > (2+y) and therefore x>y?
Thank you
Beautiful Explanation, thanks for your guidance
Answer to question appearing in slide 11: A
Question appears in the video @01:29:10
Thank you so much for making this topic and the modulus so easy to understand! :)
This is a very good video
Indeed!
If we cross Multiply in the last question how do we end up with the same answer? I’m getting stuck
Best session on inequalities, thank you so much!

Great session. Very helpful!
Such an amazing video! thank you so much for uploading this. I feel so much more confident on this topic now. Kudos! Is there also a video by Aditya over modulus?
For the last question ( 1:33:25 ) we can simply infer from the question stem that x/y > y/x. Given x&y are positive intigers, x>y.
This is because by adding the fraction x/y (both being positive) to a/b such that (a+x)/(b+y), the resulting fraction will be closer to x/y than it originaly was (i.e. (a+x)/(b+y) is closer to x/y than a/b is).
Knowing this, it must be true that x/y > y/x
Remember: (2+x)/(3+y) is closer to x/y than 2/3 is and (2+y)/(3+x) is closer to y/x than 2/3 is.
So if (2+x)/(3+y) > (2+y)/(3+x), given that the 'original' fraction is 2/3 in each case, x/y > y/x.
You can visualise this by creating a number line and plugging in values.
Because x&y are positive fraction we can multiply both sides by x&y and see that x^2>y^2 and x>y.
Once you understand the theory it is very easy to implement it directly without calculating anything. I am pointing this out because you can easily save 20 seconds knowing this, and sometimes several minutes if the question stem is not easily simplifiable.
Does anyone know what other quant topics does he cover on TH-cam ?
Just Wow! Respect!!
Thank you so much for this, it's indeed very enlightening. However, I have a question, concerning the question you solved that says if X< -3, what's X^2. Is the answer X > 9 or X< 9.
You are just amazing godamn
Super as always... really helpful
This class is a perfect gem. May allah bless you !
Thank you!
Please I don't understand why the denominator has to be negative on the inequality question
In question at 48 min of video,xyy maxvalue, can it be done like, first calculate range of xy then xy and y together. How to do it that way ?
Hello,
How come the max min rule doesn't work for Y^2 because you're essentially multiplying two ranges y and y? in 56:00? Basically if x and y have the same ranges you and you multiply them that's the same as just squaring Y but the answer doesn't show zero. Please explain. Do the ranges always have to be different?
Brilliant!!! Thanks a ton GMATclub and Aditya sir 😄

Wonderfully explained 👏🏻
I cannot see these choices A,B,C,D,E in these questions. Just one question and two statements are visible. What are these options???
5 answer choices in Data Sufficiency questions are as follows...
A) Statement 1 Alone is Sufficient but Statement 2 Alone is Not
B) Statement 2 Alone is Sufficient but Statement 1 Alone is Not
C) Statement 1 and 2 Taken Together are Sufficient but Not Alone
D) Each Statement ALONE is Sufficient
E) Statements (1) and (2) Together are NOT Sufficient
A very very brilliant video!!
Thanks a lot!
x^2 is non negative ie 0 or +ve
INEQUALITIES ME NEVER MULTIPLY BOTH SIDES WITH x^2 beause of the above reason.

Thanku
GOLD video Thank you!
So well explained. Thanks a lot for this session.
Thank you so much for your feedback. Please like and subscribe I would really appreciate it 😇
Where can I find more quant videos by Aditya Kumar sir?
how a definite no is a definite answer at 1:27:40. did not get that part , the answer should be E , none of the options together are sufficient to answer the question. then why taken B , where option 2 alone itself is a solution.
I cannot see these choices A,B,C,D,E in these questions. Just one question and two statements are visible. What are these options???
Great webinar!
Thanks a lot sir ❤Amazing session 👍
at 1:16:45 what do you mean with the roots? I cant follow how you come to 0 and 1. Please help!

how did x^2+y^2-4xy
It comes from the (x-y)^2 = x^2-2xy+y^2. Since we have 4xy, we end up with an extra 2xy :-)

Any one preparing for admit 2023?
34:20 why can’t x+y max value be 12, when x=12 & y = 0?
Because 0 is not in the range of the values of y. The max value of y can be -3. 0 > -3.
you are awesome,

is there any shortcut to check whether -1/32 is smaller or -1/144?
Cross multiply
-1*144= -144
-1*32= -32
- 32 is greater therefore -1/144 is greater
Method 2 Logic
Forget about the minus sign
Now the denominator with the greater value ll divide the numerator more
Therefore 144 will divide more hence is smaller fraction
Now with the minus sign just the reverse result therefore greater fraction
Sir,
You are awesome!!

Got it. Understood it in the second video of the playlist.
Why if we use your technique for multiplying
-4 < x < 9
*
-4 < x < 9
to get x^2, we don't end up with the result 0 < x^2 < 81 ?
I understand logically why the result is 0 < x^2 , but mathematically , no
what is all of you all?
