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!

[@jamescarr9979]

I like your videos a lot, and I will pass them on to my nephew who will be taking the GRE in the next two years.

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

Philipp. You are such a gem to the world. Thank you so much.

Phillip! You have been a pillar of knowledge these past few days. I'm grateful for all the help you provided.

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!

[@tvishathakur8947]

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 :)

[@TheTestedTutor]

Wow thanks Tvisha!

[@misahasunke5914]

How much did manage to score then?

[@sagargupta8084]

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.

[@vsaihruthikreddy7127]

I was waiting ages for this video ... I wasn't getting Work Rates questions right in my practice tests, u gave me hope and ways to solve them ...❤️❤️

[@aadityanaik1655]

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

@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.????????

[@gregsturrock531]

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)

[@cholocatelabs]

@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?

[@TheTestedTutor]

You subtract the work rates. Otherwise just the same

[@kodsglai]

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?

[@MrMcfire2]

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

[@chasrene3]

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?

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 :)

Never knew the hero of Scotland could do simultaneous equations!

[@jamescarr9979]

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

In the last question, it says CURRENTLY take Joel. He is currently working at twice the previous rate, so it should be 3 hours.

[@irfanbasha3928]

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!

[@TheTestedTutor]

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.

[@Ansh_1190]

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!

[@ameykool08]

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 🙂
