How to Quickly Solve Overlapping Ratios

[@sydneyriemer4312]

Hi Phillip, thanks. Another strategy could be to write the ratios as fractions labelled by what they represent, and then multiply or divide the fraction accordingly until you get the desired ratio. This would be similar to switching units by cancelling out terms. For the first example, apples to oranges (A/O) = 3/4 and pears to oranges (P/O) = 6/5. In order to get the desired ratio, apples to pears (A/P) you need to divide A/O by P/O so that the O's cancel out and you are left with A/P. This works for multiple ratios too. Might be quicker than writing out a table and I think it's pretty intuitive. What do you think?

True, nice one Sydney

[@rabinsonrai2905]

Thanks man. I was going to skip this question because of it was so complicated even after watching this video. Nice observation .

[@sandhyapaudyal2089]

Thanks Sydney, This was really helpful and less confusing!

[@ahmedehimare9135]

Probably as long, but definitely more intuitive. Thanks for this.

[@maheendaud7615]

It's such a great trick. Thanks a lot

[@sabaaref6025]

I need to take the GRE, and math hasn't been a major focus in my studies. However, now that I've been watching your well-explained videos, I've started to love math, appreciating all its tricks and intricacies.

[@marvin0097]

Hi Phillip. I like your videos! Especially when I compare them with other videos available on youtube. Yours are always concise, direct and count with the right length! One does not get bored or frustrated because of lengthy unnecessary conversation. Thanks a lot!

[@TheTestedTutor]

Wow, thanks

[@jeanvilbertpereira9233]

Super useful! One thing I did to try to speed up in the last case was to draw an additional column on the right and then write the multiplier in each row to get all adjusted in one go. So starting from the bottom, I multiplied the last row by 5 and the above row by 6 to get the common ratio of 30 (Y10 and Y11), and then the first row by 4 to get 28 (Y9 and Y11). So we have all rows in the same proportion at once. Thanks for the amazing teaching!

[@naunhoc92]

I have different method and hope everyone can understand Y8/Y9 = 2/3 Y9/Y11 = 4/5 Y10/Y11 = 5/6 Based on the question, we would want Y8/Y10 = ?? I'll multiple all ratio together while trying to make Y8 as numerator, Y11 as denominator and cancel out Y9, Y11 by putting them on both numerator and denominator Y8/Y9 * Y9/Y11 * Y11/Y10 = 2/3 * 4/5 * 6/5 = 48 / 75 = 16 / 25

Thank you Philip for making the concepts easy and logical specially for those who are from medical background :)

[@nusairashahab3764]

Hi. Philip. Thank you so much for the amazing tutorials. I am struggling with overlapping sets. Can you please make a video on this topic? It would be of great help. Thanks in advance.

[@TheTestedTutor]

Great suggestion!

[@brighttawiah3079]

Please Sir this method can also be used using the Chain Rule For instance for Question 1=Apple/Pear =Apple/Orange x Orange/Pear 3/4 x 5/6=5/8 For question 2 same method apply Y(8)/Y(10)= Y(8)/Y(9) x Y(9)/Y(11)x Y(11)/ Y(10) 2/3 x 4/5 x 6/5= 16/25 or 16:25

[@ronakmishra8996]

Bro in the 1st one it will be 6/5 right why took 3/4 x ""5/6"" instead of 6/5 And in the second ques 2/3 x 4/5 x ""6/5"" should be 5/6 right? i see that you flipped the last values in both ? can u explain

[@syedrahmani512]

Please make more quant videos..I am giving my gre next month and your videos are really helping me alot..Please upload more and more stuff 😃

[@TheTestedTutor]

Yes I will syed

[@shibanisabnis790]

Thanks for your videos. They really really help!

[@matthewpotash7650]

Great tip for the overlapping ratios. This way you are not comparing apples and oranges, so to speak

[@TheTestedTutor]

Very true!

[@eyewuenemurphy-akpieyi3544]

I am preparing to write the GRE May/June. I want to know if I would have covered all the needed topics in quant and verbal if I follow your videos especially the quant videos divided into weeks. Also what practice question bank is better magoosh or ETS?

[@achaleshwaripatil5968]

Hey Philip, Great suggestions and easy tricks given by you. Thanks for sharing :) . Request you to kindly share some strategy videos on work and time, Pipes and Cisterns, Time speed and distance. Would be of great help

[@TheTestedTutor]

Great suggestions!

Amazing as always! Thanks philip! #gre #grequants #quants

[@yousefalzein2765]

thank you so much brother on your efforts i appreciate that, please i need your help and your advice, i did my gre actual exam and get 153, studied from manhattan 5lb, manhattan strategy, ETS official guide and ETS quantitative reasoning book, and magoosh 589 quant questions, what i must do it to get score more than 155 in quantitative reasoning and how many questions must i solve correctly in each section to get more than 155 in GRE quant. thanks a lot

Thanks for your wonderful videos. can you please add this question to your probability example video. What is the probability of forming the word “ADDS” by picking 4 cards at random and kept in the same order out of 50 cards given with 10 cards having “A”, 10 having “S”, and the remaining 30 having “D” on it?

[@TheTestedTutor]

Great idea. Letter arrangement can be one I do soon.

Hey man keep making videos your videos are really instructive so yeah keep going and maybe start something like 5 to 10 dollar per month service just like greg mat once you built strong community

[@akhilkalaga141]

hi man...a little doubt here in one of the Princeton GRE tests, s^2=64 then s = +8 and -8 also, why is a root of 64 equals only 8 and not -8 as well...what is happening here??

[@TheTestedTutor]

If you see the root sign, that always means positive root. So just +8. If you don't see the sign, just x squared = 64, then there is a +8 and -8 solution. Weird but true!

How to find the required ratio to get a final ratio?

[@AnsImran]

2:00 clear layout ! Happy Students !😂

[@ishanpathak2526]

Great

[@mahirlabib4512]

Great video but I found an easier way I think. Rewrite both in terms of oranges, then substitute in the required ratio. A=3oranges/4 and we have P=6oranges/5. So A/P=(3or/4)*(5/6or)=15/24=5/8. Hope this helps.

[@TheTestedTutor]

Great tip! But for harder overlapping (like 4 or more sets), subbing could get quite difficult

[@mahirlabib4512]

@@TheTestedTutor I agree! I will keep in mind of your row technique for bigger problems. Subbing can get risky for more than three variables!
