It's the best video i've ever seen the most useful video ever posted on RUclips when comparing knowledge/time. I am learning 1000 new info per sec
Glad it was helpful!
Thank you so much! another way of finding the breakeven point is by (FC/Cm*) CM= Contribution margin or simply P-VC
Great tip!
@@HackingtheCaseInterview Am glad to help!
Watching this with two days to go for BCG…here goes nothing!
You can do it!
How was it????? Im doing mine soon huhuhu
How was it??
Can I network with you and get your LinkedIn?
Again, thank you so much! for the market sizing case, one suggestion is to start with the total # of vehicles registered to skip a few steps.... just an example and hope it helps!!
Great suggestion!
But how do we know that how many cars are already registered or owned by a house hold ? As we know that 1/6th number of these total*4 are gonna replace their tyres, and if you use this registration approach, please share the complete solution so that we also know the other way of doing it thanks
By far the best video on math
Glad you found it helpful!
What a brilliant summary video!
Thanks! Glad it was helpful to you :)
Thank you so much! This is the most helpful video. I love how you lay everything out so clearly!
Glad it was helpful!
It's a good video but I was asked to do price elasticity of demand at my interview.
Sheesh. How did it go?
I am preparing for Newton consulting interview. And I think it is a very helpful video. Wish I will be successful!
You can do it!
I did the Newton consulting assessment centre. This is not how it was like lol. It was very different
This is excellent❤❤❤
Glad you found it helpful!
Really liked the video, never though of using abbrivations, i always just told myself to equally remove 0s on both side, but it make more sense just adding a letter like "T, M & B". Is the any case you woudlnt use the abbrivations?
If the number is less than a thousand, then no real point using abbreviations. So, any number greater than 1,000 can be represented as an abbreviation of some sort
Can someone explain why 60% is reprsented by 1.6 instead of .6 in the algebra example?
So we are given this year's revenues which is $100M, and this is 160% of last year's revenues hence we use 1.6 instead of .6
Thaaank youuuu!!
You're welcome!

Can you please explain rational behind rule 72
It's a helpful trick to help you estimate growth when given a growth percentage. Often useful to sense check a calculation or provide a back-of-the-envelop estimation. Hope this helps!
Thank you so much. And, isnt the expected value around the 7:25 hour mark $60M?
You're welcome! It should be $72M if you do the math laid out there
8:12 Can someone explain why it's considered 1.6, i.e. why is it calculated as (1+0.6)? Also, why divide both sides by 1.6?
So we are given this year's revenues which is $100M, and this is 160% of last year's revenues hence we use 1.6 instead of .6. We are dividing both sides by 1.6 so that the coefficient of x is reduced to 1 and thereby we get the value of x. We need to divide both sides otherwise, the values on both sides of the equality sign will not match
Great video!
Thanks!
as for profit "pizza" question why you don't calculate rent cost
great video!! preparing for a mckinsey interview right now… thank you, i feel so much confident now 🥸🥳
