Those who have doubt about 5/7,
To find SP, you can actullay do : 210x * 2/7 = 60x . Now 60x should subtract from MP: 210x to get the SP: 210x - 60x = 150x
Sir did 5/7 to directly get SP using multiplying factor decrease formula ( 1-2/7 ).
Thanks
❤
thanks bro same doubt tha
2/7 decrease then, it will be 2/6 increase right?
@@BharathKrishnan-l6r no for 2/7 decrease there would be 2/5 increase.

5 years have passed and still this content is GOLD
We cannot find such a good teacher even after paying so much money, thanks a lot sir, you are lifeline for those who can't afford high coaching fees.🙏❤️
Those who have doubt about 5/7,
You are finding SP directly from MP ..(n/n-d) is not Required .
210X is 100% which is 1 Subtracted by 28.56% which is 2/7 . So (1-(2/7)) = 5/7 of 210 = 150X.
Now CP is 150X which is exactly 28.56% Less than MP (Simple Math)
(Math Works out 30% of 210X is 62 - 210-62=148 {which is around 150x} -Math Works out ) .
If you do 2/5 * 210X = 84X which is 50% (105x) less than 210X (math doesn't works out ) .
Note (To Keep it Simple) : Only use (n/(n-d)) formula to find MP from SP and (1-(n/d)) to find SP form MP
thank you soo much!! the last line (note) was a game changer hehe
it should be 1 - (n / n-d) of SP = MP
Best coaching. You are like the Anand sir of super 30 for us CAT aspirants.
watching and clicking on most ads that come up when watching sir’s lectures bc that is the only way for me to pay back for this gem of a course
Bro sir ki full classes kisi app ya website pr hai kya ?
Is this playlist of 131 videos is complete or not ?
Paid somewhere but learning from your videos. Lovely explanation 👌 I won't say thanks because it is not enough for you ❤

Sir, you are awesome. Huge respect for you sir.
This is free content that is why we are not valuing it. If anyone paid a single penny for this then only they understand the value of this content.
Thank you, Sir. 🙏
Now he's on unacademy 🤦♂️
how nicely u have explained this concept right from basic to advanced level in a very simple and understandable manner.Thanku so much sir.
As a times student I can say this content is better than times 20x times
even if you use 2/7 then 210* 2/7 is 60, then new sp = 210-60 i.e. 150
Hey man thanks I was puzzling in this particular part 🙏🏻
Thanka
Pin this comment @Rodha
If we assume MP=100 then the question becomes quite easy to solve.
MP=100
SP will be 80
CP will be 64
After giving discount of 10%
Sp will be 90
Profit will be 26
Profit%= 26/64*100= 40.625 answer
exactly
How would we calculate mark up % by this method ?
@@shivanitripathi9248 ((mp-sp)/mp)*100
Hey how the cp is 64 ? It's mentioned 25% profit so if we subtract 25% from 80 (S.P) , The CP should be 60??
@@shivanitripathi9248 we're just assuming, let's say MP is 100.
HAPPY TEACHER'S DAY SIR
Thank you so much sir. You are the best educator. You explain in such a way that anybody can understand the toughest topics. The way you have been giving us all the CAT related content & that too free of cost is just truly commendable. We will be forever grateful for your hard work sir. May God fulfill all your wishes 🙏
I am serious cat aspirant , as of now I am completely dependent for my basis for you , i am enjoying each and every lecture , thanks for the content , i will definately update my result to you personally..
Thanks you so much sir 😊😀
Same here
Top level content! It's impossible not to be amazed by the concepts, and the methods even for the small calculations are not just fast but also taught with such clarity and simplicity.
On the scale of 10 I will rate Sir, as 10. You only saved my CAT.. REGARDS.
How much percentile you got
Thanks to Chat gpt . Sir ka approach fast hai ( achha hai par break leke padhna padega ) overall . Yahi to chahiye 👍👍👍
Sir can you please arrange the sequence of percentage profit and loss videos.
Thank you sir just learning the gem concepts nd solved correctly while pausing ur videos ..u r God 🙏
Sir in 23:28 how does 28.56% = 2/7 when discount decreases you told us n/d decreases then n/n-d
increases, so sir when 2/7 decreases how does it become 5/7 ? It should have been 2/5
We Calculated sp so we only did dec therefore 5/7
Yes same doubt
Answer should be 5 % mark up...right??
@@navneeetmishra no bro how?
Agreed.
Wish i had someone to teach me this when I was little. I wouldve aced every math exam and would be a smarter person today.
Sir you are making awesome videos . Thank you so much sir it helps us so much
08:20 Another method
if we suppose MP =100 then SP = 80 & CP=64 {by 1.25CP= SP}
then for discount of 10% MP remains same SP =90 & CP=64 So, P= 26/64 x100 = 40.625
hey..how come CP is 64? I don't get it.
I didn't understand the second part in the last question. For 28.56%, we take 2/7. So shouldn't we multiply 210 by 2/5 (n/d-n)?
I also how 5/7 🤔 here 2/5
infact why should we use 2/5 bcoz we know mp , so its should be 2/7 of 210
Me too m a bit confused with that part. If possible please help me out.🙏
We are not increasing the sp in the second case. See the method that u are referring to is used to determine the percentage of increase / decrease. But for sub part 2 of last question, we already know the MP on which we have to give a discount. So new SP will be MP ( 1 - D%) = MP ( 1- 2/7) = MP (5/7)
2/5 is the percentage increase of SP to MP. If we do, SP i.e 150 (2/5) we get 60. 150+60 = 210 which is the MP
Sir u made profit and loss so easy for me to solve which was earlier a hectic topic and I was wondering I could I solve them
@rodha sir ji, humble to you, kya aap screen ka colour white se black kr sakte ho? Because aankho pr kam roshni pade aur aasani se bache video dekh paye ❤
Thank you for the videos sir. I have a request ,your videos is not numbered properly..it's quite tough for find it properly. Could you please number it properly like average - 3rd video is missing..some of it not in sequence.
You are blessing us with our content sir, keep up the good work. 💗 May lord bless you
Tqsm Sir i hv never imagined tht i wld enjoy % ,Profit & loss this Way easier.
IN the last qn for finding the discount percentage the eq is 73.5/210 *100 so cancelling the zero we will get 735/21 so 1/21 is 4.76 % so, it should be 735*4.76= 349.86 percentage i know this is not right, but still want to know the answer, if 1/7 is 14.28 and 2/7 is 2*14.28 = 28.56 percentage, then 1/21 * 735 should be tecnically 349.86 percentage right?
Hi Denesh,
Just a small mistake by you here, it should be 735*4.76% (you missed %age) i.e. ideally 735 is multiplied by 0.0476 and not 4.76.
Hope it clarifies!
Thanks.
For solving these question my friends are taking about 30sec at least and it just too me 10-15sec max. and they have taken paid courses of Elite Grid but are not fast. All hail to You sir
For 24:00,
(n/d+1) = 2/7
Answer becomes '150', that is correct!
But when we go for the inverse
i.e., (n/d) = (2/6)= 1/3
= 33.33%,
which makes it to '200x'
Inverse is not getting equal, as given for the markup price,
How?
Further theory:
210x(5/7) = 150 ; for decreasing value 2/7
Also,
150x(4/3) = 200; for increasing value 1/3.
Help sir..
its not d+1 its d+n
This is gold!
Any body is confusing abt 2/7 or 5/7 they should try discount percentage formula...(D% = D/Mp x 100) put value and u will easily get 60....answer 👍🏽💌😅
Doubt in second part of last question. 75% Profit is already applied on CP than SP becomes 175x now, how we can consider MP to calculate new p% when profit already applied to get MP. THIS 210 MP COMES WHEN PROFIT OF 75% APPLIED , HOW THIS CAN BE USED.
Even I have the same doubt.
If u get it , can u plz explain to me ?
According to google, marked up price = SP - COST. And according to sir, marked up price = MP - CP. Which one is correct!?
That is profit
Happy teacher's day sir!!
Thankyou so much sir you are helping thousands of students
Sir big fan of your teachings 🙌🏻🙏🏻
sir where to practise these kinds of sums
If anyone got the right order to watch arithmetic videos please comment
In the last question, why have we kept the MP constant as 210x and not calculated the new MP with profit 136.5x?
Same question
Because it is fixed.......
Hello Sir , in this video , 1st question why you have taken CP as 100x ...Why not only 100 ?
Please tell
Aise hi x se confusion ni hota. 100 assume karne pe kahi Rs 50 actual amount add karke log 150 kar dete hain. But that is wrong. 100x + 150 hoga na.
@@Rodha ok Sir ....Thankyou
sir can we use this formula for finding mp =(100+gain%)/(100-discount%) * cost price
Please help sir, you used percentage increase/decrease concept in first 2 sums and then multiplying factor concept in the last one. Can anyone explain when to use what? It's a little confusing.
Going by the first 2 sum it should have been 2/5 instead of 5/7
Yes,you are right
We are not increasing the sp in the second case. See the method that u are referring to is used to determine the percentage of increase / decrease. But for sub part 2 of last question, we already know the MP on which we have to give a discount. So new SP will be MP ( 1 - D%) = MP ( 1- 2/7) = MP (5/7)
@@deepshikhadas8545 thanks di . U cleared my doubt
12:00 i have a doubt,
if the selling price of the product after 20% discount is 125 then the Marked price would not be 150 ? (20% of 125 = 25) 125+25 = 150.
But according to sir's formula we got the answer as 156.25!!!
Can someone please explain me this as i am a bit confused!!!
Discount is always calculated on the marked price not selling price ... So, according to u if 150 is the marked price then calculate the 20% discount on it u won't get selling price as ₹125...
And try calculating 20% discount on ₹156.25 then u will get the selling price as ₹125
sir you are the best
🤩🤩🤩🤩
Is this is a last video of percentage.....
Thank you soo much Sir🥰🥰🥰
sir 210 MP was being calculated for 75% discount right? why did we use for next 2 ques as well the same MP?
It's calculated on 75% profit not discount....otherwise my doubt is also same
hey, generally speaking, in a showroom , a cloth if priced at 1000 it is MP, so regardless of the profit or discount fluctuating the mp stays the same, however selling price will differ according to the discounts and profit margins. hence same mp here is taken in all scenarios, feel free to correct me if im wrong. this is just my understanding .
Why is multiplying factor not used when doing the profit and discount as increase and decrease
sir, when 28.56% discount is given instead of 16.66% then why you solve it by 210x , why it shouldn't solve on 175x
Discount is given on MP not on SP
exactly
Your videos are blessing sir 😇
Sir your teaching method is so impressive!!
Like after % 3 we should watch averages of profit and loss?
Nice teaching skills
In 25% discount 20% profit, 5% discount question why is the answer different if we take MP as 100x instead of CP as 100x
Answer is same, try it again
discount is calculates in Cost price right?? then why did sir calculated it on mark up price?? can anybody let me know that
Discount % is calculated on Marked price not cost price because discount is given on the price show to the consumer(marked price) not the actual cost price : the formula is discount/ marked price *100
Hello sir!
Your videos are making my concepts clear. Thanks for taking the time to help us. At 9:52, are SP and MP inversely related? I guess not. If they are not, we are not supposed to apply the formula, right?
they are inversely related since if on markup more discount is allowed, the profit would reduce, and vice versa.
As always outstanding
Thank you so much sir.❤❤
Please someone explain me 2nd last question
If we didn't consider 100x as cost price then.

Why CP 100x and not 100? Pls someone explain
Because the value is unknown. X represents the variable.
this video is not in order of the playlist
20% is 1/5 . So n/d is 1/5 hence n/d+n is 1/6 . So why he wrote 1/5??
Exactly my point too
Its 20% decrease thus n/d+n = 1/5 while n/d = 1/4
