3 years later and your comment is so accurate. For the last question I indeed put 1/2j (for doubling joels rate, I forgot the 1 is his output, the widget, and J is J hours, so doubling his hours would mean he takes TWICE as long). Flipping it to 2/j is the correct one as it would be doubling the rate he produces widgets, and was then able to solve it. Thank you for your work and I hope you're well these days!
Thank you SO much, Phillip ! You're truly a godsend. Really appreciate how you explain everything in detail. It's very kind of you to avail all this high quality material to us for free :D
Following your previous methods thoroughly, I could answer all the questions easily and quickly, even though I’ve been away from math for around six years. You’re a fantastic teacher, Philip! Hats off to you!
Great content! Phillip. For these questions, I do always follow this trick and may be you can share this trick with others as well, in case you haven't already. Trick is to always assume work as multiple of time figures in the question. Let's say for the last questions instead of choosing 1 widget work as 1.. take a multiple like 6. This ensures your rate to never be in fractions and enables you to add rates easily.
Hey Philip! It's been around 2 weeks that I've started watching your videos for my GRE and THANK GOD I found your videos. Every single video has sooo much to learn from and your tricks are just amazing. Thankyou so so much for being an angel :)
This is amazing! After watching the previous Rates video, I was able to do all the problems in this video by myself! And I'm particularly scared of this topic!
Yes, me too Shweta, When I watched this exercises goosebumps inmediately, But I know, this is a process, thanks for amazing videos Phillip. Greetings from Peru
Hi Buddy, I love the way you explain things, Gained a lot of wisdom in these couple of weeks. Just wanted to add a standard format as it helped me understand the problem much better. Prepare a table for all WAT related problems and Use the formula : T*A = W for calculating Average Time Average Work 4 1/8 1/2 16 1/4 4 ? 3/8 5 Explanation for the values below. As he mentioned we can add averages and not time. 1/8+1/4 = 3/8 Therefore, T = 5*8/3 = 40/3
Thank you so much for these videos Philip, can’t thank you enough for them. I have my test on the 10th of this month and your videos have been incredibly helpful.
I just started watching your videos they r amazing. Kindly help me where can find hardest problems on almost every topic. Preferably, free material for practice.
Please do a video on Coordinate geometry with a graph given and we have to get the equation out of the graph ....finding it very difficult to solve them in the 5lb book
Great video! Thanks for uploading it! Do you have a video about factorizing polinomials? I have seen your video of prime factorizing and it really helped me! Thanks for your work
@The Tested Tutor Hi Philip! The question is asking for hours that Joel takes "currently" to finish the work on his own. His speed is doubled means it will now take 6/2 hours= 3hours to finish the work individually.????????
For the third question I solved a simultaneous equation with Rj and Rv. I sometimes get confused with 1/j and 1/v. I have my GRE in 2 weeks, I hope it goes well :)
Hey Philip! On the last one I didn't quite use your method, but I'm curious to know if you think it's valid It made sense to me to set it up like J + V = 1/3 2J + V = 1/2 rearrange, then subtract 2J + V = 3/6 J + V = 2/6 ------------------- J = 1/6 J = 6/1 (individual time)
I am really enjoying your tips and tricks. Thank You. I have a question regarding the final exercise in this video. I wrote the first equation as x+y = 1\2 and the second one as 2x+y = 1\3 and found the same result. Is it okay that way?
Hey Philip! It's a great video. Thanks once again for such wonderful video. I have been told by someone that's in December set the GRE questions are always difficult than other time. Is it true? I am thinking about giving test by the end of this month. Please tell me. I will schedule my test accordingly. As I am looking for fall 2021 intake.
There is a short-cut with the final question: 1st: Work out both rates: (1) R1 = 1/6 (2) R2 = 1/4 2nd: The difference between these two rates (i.e. Joel's double speed!) is (1/4 - 1/6 = 1/12) 3rd: Work out Joel's rate: 1/12 x 2 = 1/6 4th: His time is simply the reciprocal = 6 = Answer
Hi Philip, thank you for all of your videos. For the last question I set up my equation as (1/3) -J = (1/2) - 2J basically doing the combined rates minus Joel's rate. I got the same answer. Is this a correct way of doing it or did I just get lucky?
Hi Philip. Hope you are having a good day. 🙏For gre, is it sufficient to learn Magoosh 1000 words and 333 barrons high frequency words??? Or do we need to learn any other words ? And also I have my gre exam scheduled on day after tomorrow. Any last minute suggestions from your side ?
Hey! Thanks for your videos! Can you clarify this for me: I have been using the formula " Output = (No. of workers) (Sum of each worker's Individual rate) (No. of hours) " , but not sure why this doesn't seem to work in your problems.. For example, in the first example of Ana and Samaiyaara, I wrote down the formula as: Output = (No. of workers) (Sum of each worker's Individual rate) (No. of mins) 1/2 task= (1 worker) (Ana's Individual Rate) (4mins) 4 tasks= (1 worker) (Samaiyara's Individual Rate) (16mins) which implies, Ana's Individual rate = 1/8 and Sumaiyaara Individual rate = 1/4 Working together, their combined rate is 3/8, so now the formula becomes 5 tasks = (2 workers) (3/8) (No. of minutes) Solving for time, I am getting 20/3mins unlike 40/3. Can you point me out where I am going wrong? Thanks!
I don't know where that formula comes from, seems wrong to me. Why would 3 workers with a combined rate of 3/8 be any different to 2 workers with a combined rate of 3/8? We have already combined them. Maybe that formula works if you do average instead of sum. My method is totally different as you can see.
Sir, Please make video on multiple workers problem( Ex. 20 workers pack 20 boxes at constant rate in T time how much time will 30 workers will take to pack 100 boxes)
Re the problem with Joel and Vivek -- I used your rule about combined rates being a sum and, rather than resorting to algebra, I subtracted the old rate from the new rate: 1/2 - 1/3 = 1/6. Is this acceptable?
Q- in a garrison there are 600 soldiers and food supply they have is sufficient for 30 days. After 10 days, 200 more soldiers join. If rate of food consumption is same for every soldier, how long will the food supply last after these 200 soldiers joined? A - 15 Unable to apply the concepts learnt here, can u help out!
You can do it like:- Total amount of food for 30 days= 600×30=18000 portions In 10 days 600 soldiers will eat = 600×10= 6000 portions So we left with 18000-6000 =12000 portions After that 200 new soldiers joined so total soldiers will be 800 Therefore, Number of days it will last = 12000/800 I.e. 15 days Hope this helps 🙂

Hi Buddy,
I love the way you explain things,
Gained a lot of wisdom in these couple of weeks.
Just wanted to add a standard format as it helped me understand the problem much better.
Prepare a table for all WAT related problems and Use the formula : T*A = W for calculating Average
Time Average Work
4 1/8 1/2
16 1/4 4
? 3/8 5
Explanation for the values below.
As he mentioned we can add averages and not time.
1/8+1/4 = 3/8
Therefore, T = 5*8/3 = 40/3
This is so helpful Phillip. and yes I see your favorite word there...nuances...Many thanks
yes well spotted!
That was just GENIUSSS!! Philip.

It made sense to me to set it up like
J + V = 1/3
2J + V = 1/2
rearrange, then subtract
2J + V = 3/6
J + V = 2/6
-------------------
J = 1/6

yes
@The Tested Tutor For the last question why the rate doesn't become 1/3 because, the question mentioned doubling the rate right??
How do you solve the working the against each other things like filling the tank?
You subtract the work rates. Otherwise just the same
can you pls do advanced arithmetic means problems?
Such as?
Hi Philip. Hope you are having a good day. 🙏For gre, is it sufficient to learn Magoosh 1000 words and 333 barrons high frequency words??? Or do we need to learn any other words ?

The more the better. If you did those two, plus my vocal videos, I would say you are mostly prepared vocabwise
or we can take the lcm of 3 numbers and then divide each number by lcm to get each fraction of work piece , thanks :)
Hey! Thanks for your videos! Can you clarify this for me:
I have been using the formula " Output = (No. of workers) (Sum of each worker's Individual rate) (No. of hours) " , but not sure why this doesn't seem to work in your problems..
For example, in the first example of Ana and Samaiyaara, I wrote down the formula as:
Output = (No. of workers) (Sum of each worker's Individual rate) (No. of mins)
1/2 task= (1 worker) (Ana's Individual Rate) (4mins)
4 tasks= (1 worker) (Samaiyara's Individual Rate) (16mins)
which implies, Ana's Individual rate = 1/8 and Sumaiyaara Individual rate = 1/4
Working together, their combined rate is 3/8, so now the formula becomes
5 tasks = (2 workers) (3/8) (No. of minutes)
Solving for time, I am getting 20/3mins unlike 40/3.
Can you point me out where I am going wrong?
Thanks!
I don't know where that formula comes from, seems wrong to me. Why would 3 workers with a combined rate of 3/8 be any different to 2 workers with a combined rate of 3/8? We have already combined them. Maybe that formula works if you do average instead of sum. My method is totally different as you can see.
Sir,
Please make video on multiple workers problem( Ex. 20 workers pack 20 boxes at constant rate in T time how much time will 30 workers will take to pack 100 boxes)

Re the problem with Joel and Vivek -- I used your rule about combined rates being a sum and, rather than resorting to algebra, I subtracted the old rate from the new rate: 1/2 - 1/3 = 1/6. Is this acceptable?
yes
For Indians, maths is not that challenging. However, could you please give me some advice about how to deal with vocab section.
Q- in a garrison there are 600 soldiers and food supply they have is sufficient for 30 days. After 10 days, 200 more soldiers join. If rate of food consumption is same for every soldier, how long will the food supply last after these 200 soldiers joined?
A - 15
Unable to apply the concepts learnt here, can u help out!
You can do it like:-
Total amount of food for 30 days= 600×30=18000 portions
In 10 days 600 soldiers will eat = 600×10= 6000 portions
So we left with 18000-6000 =12000 portions
After that 200 new soldiers joined so total soldiers will be 800
Therefore, Number of days it will last = 12000/800
I.e. 15 days
Hope this helps 🙂
I found these easy tho😊
Do you think that advanced work rate questions are a common occurrence on the GRE quant?
Only at the highest level
👌👌👍👍
why not this 1/2+1/3= 1/6 (RATE) , THEN FLIP IT 6 hours
This kind of question is the most annoying one
Hopefully not as much now Khoai
