How to Master Absolute Value Questions on the GMAT

[@lapgandhi]

I am inherently good at quant and got a Q51 in an official mock. However, I did not know around 80% of the techniques used in this video. Proud to say this webinar was useful for me and I am sure would be for everyone.

[@kunalshinde7293]

If it had been the question of ‘weakening the argument’ I would have gone with your comment as the answer.😅

[@joeboxter3635]

@59:00 Type II, @1:01 Type III & Type IV @1:06 Type 5

[@bharathravi6517]

Answer to 700 ( last question ) is both conditions are sufficient. On solving the given equation, we will get two solutions x=y or x+y=-4 (remove the mod and solve by type3). To remove x=y solution, we need a statement to say x and y are not equal. XY2, Y

[@vikramaditya8126]

So ultimately what is the answer ..what is the value of X+Y? Is it -4?

[@samriddhisinha1334]

thanks so much!!

Aditya you're doing God's work. I'm watching this way 2 years in the future and this is absolutely incredible. Thank you for the work you are doing.

[@NehaVerma-u1w]

Wow, I am speechless after watching Aditya’s inequalities and absolute value sessions. No one (I mean it… absolutely “No One” 😊) could have explained these topics better than him. MUST MUST WATCH, if you really want to understand these concepts !!

[@mileeme]

Wow Aditya Kumar is brilliant at breaking down and explaining complex problems.

[@FinDiary]

No side hustles, straight to the point. Awsome Aditya. Very helpful. Im struggling on accuracy of Absolute values. This is saver for me :)

[@SnigdhaPankaj]

I have never dreaded a topic more than this. Thank you so much for making it a cakewalk!!

Thank you! Stay tuned as Aditya Kumar is coming back on KZbin with more such powerful sessions. Stay Subscribed!

[@sayaknag4918]

The problem in 37:55 is wrong I think. X>|y| this should be the case. only X>0 and X>y will not solve the equation. Ex: X=1, Y=-2

[@physicsnovice656]

yeah, was thinking about making a comment that there's mistake

[@jasonvoreseeas6578]

Yes that's true but the second part is correct where 1st statem is y>0 and 2 is x>y is accurate

[@vaishnavisharma8405]

Yeah that's right. But while solving it he said the magnitude of x should be greater than the magnitude of y; and if we say |x| > |y|, and x>0, then it would suffice.

[@filippoiguera3224]

Thank you so much, Aditya! Wonderful lesson! Thank you also to the GMATClub

[@aparnabaskaran2448]

Thank you so much for this video - Aditya and GMAT club! I've been struggling with inequalities since the beginning of my prep, and I'm so glad I found this video. FINALLY, I feel like I have an idea of how to approach these questions. How you've managed to make even this topic seem easy is beyond me.

[@rohitsekar]

Thanks for really breaking things down to the very basic level and making to more interesting to learn these concepts 👍

This was an amazing session, really recommend going through it

[@gmatclub]

👍 Thank you for the feedback. We appreciate it as we look for ways to bring the right topics to our channel.

[@houdasrhir3216]

The question around minute 38, I think the question should be is x>IyI? and not is x>y. Therefore, the answer to the question should be E and not C. For the second case where the conditions are y>0 and x>y, yes the answer is C. Please correct me if I am wrong. Thank you very much for this very insightful video.

[@gmatclub]

I am not sure if Aditya (the instructor in this video) is actively following the comments posted here. Perhaps it would be a good idea to post this question and your query in GMAT Club quant forum to seek feedback from the community and experts. gmatclub.com/forum/quantitative-7/

[@gowriuh09]

In the question is x|y| > y^2 along with conditions x > 0 , x > y we can also add one more that is y < 0 bcz in the equation y is inside mode on the L.H.S and getting squared on the R.H.S where it converted into postive both the sides .

[@Freelancer-rv8lo]

By far the best video I have seen on this topic

Wonderful video - thank you Aditya and GMAT Club

[@Makitatata]

In 43:20, why do we make the sign of the entire absolute variable be negative, and not just the variable? Meaning, if we are plugging in the variable x, wouldn't we only change the sign of the X?

Hello aditya, great work but help me umderstand why in 33:44 a and b cannot both be negative because |-2+ -3| which is |-5| is not < |-2- -3| which is |1|

[@deepakpatel2292]

Thanks a lot Aditya. Both Inequality and Abs value videos are very helpful and packed with concepts :).

[@caroleg1997]

hi gmat club for type 4 absolute values in 1:05:50 why not take the roots like in the case of type 3 and have x and y to be less than 0? please help. I cant seem to move forward from this

[@gmatclub]

Hi Caroleg, not sure if Aditya is still following this comment thread; I think it will be more helpful if you just post your doubt in the Quant forum on GMAT Club (gmatclub.com/forum/quantitative-7/) and make sure to tag @Bunuel in your post; I am sure Bunuel and other GMAT experts on the forum will help address your question.

[@tvishaverma3689]

37:38 - 2nd condition should be x>|y| -------> eg. nos to solve this, x=2, y=-3 ----> x|y| = 6, y^2=9, LHS

[@raghavkabra4851]

38:25 I have a doubt, wouldn't it be 'not sufficient' "Option E" as the conditions given doesn't clarify y>0??

[@sanskarmurarka1973]

i think the question was whether x is positive

[@michiesim]

so happy i found this session! thank you aditya

[@aishwaryanarayan617]

Fantastic class sir! But where is the last question you just mentioned at the end (700 type question)?

[@massonchacon4258]

Hello, wouldn't we need in the problem "x * IyI > power(y , 2)", the information confirming that y != 0? This is given in the second instance of the problem, where y > 0 and x > y, but not in x > 0 and x > y. Therefore, I would think the info from both last statements to be insufficient. Thank you for your time. I hope to get an answer, please.

[@gmatclub]

Please mention the time stamp and we will see if that question is discussed on GMAT Club.

[@ravleenmalhotra1939]

In the question ‘what is the value of y?’ Can I directly say that 1 will give me 2 values of x coz degree is 2 which means I can’t find y directly. Moving on to 2 gives me 2 possibilities which when I check in 1 show that y will be imaginary if x is -8. Giving me my answer c and y=14. Please tell me if this is the correct way to see this?

[@ashiqkorikkar]

In 38:56, Shouldn't the answer be E instead of C? Don't we need |x| > |y| (instead of x > y)? If x = 2 and y = -3, then LHS is 6 and RHS is 9 : then x|y| < y^2 If x = 4 and y = -3, then LHS is 12 and RHS is 9: then x|y| > y^2

[@vamsiacharya2099]

You're right! But if we know y>0 like in the second condition, then x>y will suffice.

the answer should either be E or changed question: prompt: x|y|>y^2 ? 1. x> 0 2. x> y you don't know if y >0. statement E. or change question to "x|y|>y^2 ? if y > or < 0" then answer is statement C

[@karthikvenkat6333]

Correct. Nice observation

[@jaanvidaiya]

Either way y is going to be positive or 0 so c is correct

[@jaanvidaiya]

Either way y is going to be positive or 0 so c is correct

@@jaanvidaiya but based on "the prompt" is x*abs(y) > y^2 and then the info from the statements.... if y is 0 then the term is not greater, if y is greater than 0, it is.

We can do it with that method, but it'll only take more time. Instead, if we think that 5-x is greater than or equal to 0, then it'll make our life much easier.

Hey guys, I have a question linked to this one. During the whole webinar the explanation was that |x| = something, we can analyze that X => 0, but in this problem, the approach was to take the something =>0, and the results are different. Can anyone tell me why use 5-x =>0 instead of x-5 =>0. Thanks in advance.

You are incorrect for the question at 35:07 the correct answer is x > |y| for the equation x |y| > y^2 You have x > 0 and x>y However, to prove this incorrect. Use x = 4 and y = -5 These numbers satisfy your condition of 4 > 0 and 4 > -5 The do NOT satisfy the original equation. 4 x |-5| is not greater than (-5)^2
