I wanna say again. In my school i always used to feel i am naturally weak in Maths and used to be jealous of students who were constantly scoring good. I changed more than 15 coaching classes in the time period of class 10th and 12th with no improvement and waste of time and money. 4 years later now after 12th class, i am watching these videos and honestly everything came to me so naturally because of Ravi Sir that changed my whole perception about my life. I never understood SI CI in life until now. You are God for Students like me who thought we are a Maths failure
I came here after the suggestion of Shweta Arora mam , and it is worth visiting your yt channel sir , your concepts are amazing ❤️ Huge respect for your dedication 🙇♂️
@@priyanshiagarwal4023 you should get 48000 . R=1\(20/3) right so when you cube this(time is 3 years) you should get 8000/27 as 20 cube is 8000 and 3 cube is 27 not 9. After this you mutliply this 8000/27 with 162(1 unit ) then you get 8000*6= 48000. Hope it helped you .
I always hated SICI and this video really changed my perspective. I now got to know that it was not me but I was taught badly. Thankyou so much sir! please keep going! wish you all success in life
I am totally amazed by you sir how easily you teach the most trickiest part ,which I literally feared in my whole 10th class , in such a beautiful and simplest way ....thank you so much sir
the way sir has just broken down the concept so logically is really commendable. I feel really thankful to god for showing me the path to this channel....really blessed❤❤❤
Excellent conceptual knowledge delivery I have not met much teachers like u but this kind of iq and thinking base which u r teaching us it's just absolutely amazing and priceless
Sir, do u have a pdf for all the shortcut formulas in Quant and LR-DI? it will be beneficial for weekly revisions even though I will never forget these formulas..!!
6:13 is this applicable for only 3 years? In this question What will be the difference between simple and compound interest at 10% per annum on a sum of Rs. 1000 after 4 years? When i solve using the method taught in the video i get Rs. 32.10 but the answer is Rs. 64.10. When we take the formula approach yes i get 64.10 but with the method in the video I'm getting 32.10. What am i doing wrong?
Sir what will be the formula for ∆ when the time period is not 3 years whether it changes according to time period if for 3 years it was ∆3=3a+1 so for 5 years will it be ∆5=5a+1 or will it be same 22:30
Man i really love the way he teaches the only problem sometimes happens is just at 2x speed i fails to understand what he said, since i have left 10 days in snap i am lagging in some concepts trying to fix them by watching his videos hence my coaching institute is not going to teach everything from basic now, his videos are blessing for me. Just i have to play it on normal and runnig out of time also everyday.
Sir we are trying to avoid decimels. so we are using it to simply our interest in terms of whole no. units. But if the CI with which we have to compare is in a form which upon diving by total units gave a decimel point, then the whole concept contradicts. here you are taking examples that perfectly divide the CI
Amazing videos sir, but you left out Present value concept and some other small things for compound interest. Did the installment one on my own by combining the knowledge of fv and ci but plz upload present value, just following your course and tricks.
23:25 we can apply this shortcut for 4 years also? I am not getting the answer while applying this trick for 4 years. Q- What will be the difference between simple and compound interest @10%p.a. on a sum of ₹1000 after 4 years? Ans. - ₹64.10 Can we apply this trick on this question?
sir thanks for making this video. your videos give me conceptually clear ideas rather than byheart the formulas . i have watched all videos in your arithmetic playlist.
Thank you so much sir, and actually this chapter was really tough for me but after watching your videos, I loved it sir and the way you logically developed the shortcut was super amazing. Just a question, is there any more videos for this particular series, because this video ends the series and your last sentence was : "see you in the next video of SICI". Rest all this particular series of SICI had made me very confident in myself to learn the logical skill from you. Thanks a ton sir for your videos...🙏🙏
I do not understand one thing when there is a last video on a particular topic it seems that there are a lot more concepts to discuss but in the next video new topic is there. SI and CI is completed in 6 videos even without discussing difficult concept. CAT doesn't ask these simple questions, same for time and work....
Given the difference between SI for 2 years and CI for 2 years on the same sum and at the same rate of interest compounded annually is Rs.120. The difference between SI for 3 years and CI for 3 years on the same sum and at the same rate of interest is Rs.366. Find the rate of interest. Can anyone pls solve this question?
Can u PLEASEEEE provide more concepts nd questions of Compound interest- how to solve half yearly, quater yearly compounded, rate of interest,etc without THE LENGTHY FORMULAS
Sir, I have a huge respect for you and what you have done for us is unmatchable but I have attended some of your classes in Unacademy and the difficulty level of those practice question is absolutely bonkers and I just have a genuine question for you that ....the content provided by you in this channel ...is it enough concept that is required .....BTW I saw a question that was based on some equation that horified my till my feet
First we do all the concepts basic to advance. Then we go for high level questions. Aur sabko samjh me nhi aata hai high level questions itna padhne k baad. 6500+ students attend my classes there. To aata hai sabko samjh me. It's just important to study sequentially.
@@Rodha Thankyou Sir! for your response ...Its just that I was practicing and revising concepts of Arithmetic + solving questions from Arun sharma but by the time a went on with one of your videos in Unacademy that Question made me.... question all my hard work that I`ve been implementing till now and not able to solve it brought me into a void of frustration and dilemma but I guess Quants is never enough there`s always something left hanging......Agian a thankyou for your effort will never be enough.

Once again I'm commenting sir you are not just a teacher you are an educator , a life educator.
Than u sir for this concept. I don’t understand why they don’t encourage such concepts in schools.
Exactly
Most prob'ly they dont know this concept, I guess

Then [ ∆n = na + 1 ]

Bhai I swear he is a literal God. The things I couldn't do after scribbling for hours, now I can do mentally, crazy!
Phenomenal approach for solving SI / CI ,solving it with options is very tedious . Thank you sir
Never thought SI/CI would be so easy & interesting. Thank you Sir.
sir, you are one of bestest teachers I have met. Thank you soo much for everything.
Sir's videos are the best. I have been watching it clear QA& LR concepts for a month now. They are amazing.
Never knew si ci was such a easier and interesting .... thankyou so much sir♥️
Ravi sir truly justifying his words 13:57
Sir what ever i achieve in my life, i will be thankful to you❤️

Same!
Thankyou sir.... You're concepts are new n easy, and most important they are short & quick... which i believe is most important

you are an awesome man! Can you please keep a live class on zoom just for your subscribers? like a doubt session or something
Ravi Prakash search in unacademy cat section. He takes live class there
No can replace Ravi Sir way of teaching
He Is GEM

But if the CI with which we have to compare is in a form which upon diving by total units gave a decimel point, then the whole concept contradicts. here you are taking examples that perfectly divide the CI
to avoid this the shortcut is used
if the principal itself is in decimals then ofcourse there will be decimals
Generally we don't get decimals in cat exams at all .

Can you guide on the installment with CI ??

soo much amazing concepts...sir never fails to amaze us with their tricks.
Excellent concepts and teaching🙏
Bruh knowing these shortcuts makes you feel like you cheating in exam or something!!! Thank you sir!!😁🙏
9:00 the difference between ci and si should be 1
400+420+440 = 1260
400+420+441= 1261
23:25 we can apply this shortcut for 4 years also?
I am not getting the answer while applying this trick for 4 years.
Q- What will be the difference between simple and compound interest @10%p.a. on a sum of ₹1000 after 4 years?
Ans. - ₹64.10
Can we apply this trick on this question?
No the trick is only for Time periods = 3 yrs only....641 units is the difference, 1unit = 0.1 rupees, then 64.1 rupees is the difference
@@nitinaryan4281 okay, thanks for your response!
Is there 7th video of SI and CI because CI is not completed yet
What if we want calculate Different between CI & SI for more than 3 year ???? Any short cut formula???
Woww i am so surprised right now! Crazy concepts
This channel is a hidden gem 💎
sir thanks for making this video. your videos give me conceptually clear ideas rather than byheart the formulas . i have watched all videos in your arithmetic playlist.
Sir At 21:21 P=8000/27
deepak gulia he corrects that
Ravi sir ur God for every cat student your skills are so amazing sir
17:09 i'm little confused why here the rate is 1/6, while in qwes. It's given that 16.2/3
same.
as it is in % that is equals to 50/3%= 50/38*1/100 (% to fraction)=1/6
3a + 1 formula works for only 3 years or we can use for differen years by changing 3 as years mentioned
same question, did you figure it out?
Thank you so much sir, and actually this chapter was really tough for me but after watching your videos, I loved it sir and the way you logically developed the shortcut was super amazing.

Look for practice questions in Advance arithmetic series.
@@Rodha Sure sir, thank you so much for the recognition..
at 17:12; i don't know how rate percent of 16 2/3 became 1/6. My brain is not able to connect the dots. Please explain.
if you solve the improper fraction you get 16.66% which is equal to 1/6
I was thinking to leave, CI, because of its calculation part., But after watching this lectures, hope to try all the CI and SI questions
in last question value of a should be 3/20?..... isn't it??
sir where are the next ci videos that you mentioned at the end of this video....
Advanced Arithmetic Series
Thank you for uploading such amazing videos
Thank you so much sir for these amazing concepts. You make every topic easy to understand.
This 3a+1 can only be used for 3 years right?
thansk but i am noe able to get next video of this series
Sir don't leave us in the middle please 🙏 upload rest of the parts
Yes sir plz upload more videos related to it
Sir, when you will upload other videos for CI?
There hardly any time left.
its complete now practice it yourself.........
where can we find the next video of SI & CI ???
18.23 --------- Is this applicable only when T is 3 years ?
I do not understand one thing when there is a last video on a particular topic it seems that there are a lot more concepts to discuss but in the next video new topic is there. SI and CI is completed in 6 videos even without discussing difficult concept. CAT doesn't ask these simple questions, same for time and work....
Same query
remember this is only applicable if TIME = 3 years . as if time is 4 years then we can't get delta3 by this method.
Same doubt I had...if I take 2 years then would Delta for 2 years be 2a+1? Or not?
@@optimistic2 watch previous videos,,2 yr difference was also taught...but not for 4th yr

Awesome. Full chapter without traditional formulae
where is the next video???? can anyone tell me
Great explanation......kudos!!!
garda uda diya sir,,, this concept is just lightening
in the last question it will be 8000/27 not 8000/9
finally my fear for si ci has gone now
Sir is this Difference between SI and CI is only applicable for 3years??
Yes sir plz tell me also
Yes, only applicable for 3years
Are there more videos in SI/CI. I feel like it's incomplete
Given the difference between SI for 2 years and CI for 2 years on the same sum and at the same rate of interest compounded annually is Rs.120. The difference between SI for 3 years and CI for 3 years on the same sum and at the same rate of interest is Rs.366. Find the rate of interest.
Can anyone pls solve this question?
Thanku for such an amazing series of vedio.... I am so grateful to you
You made this concept look so easy.... Thank You sir
Amazing session as always! Sir ke concepts helps to save a lot of time and improve iq as well!
Can anyone please tell why did sir take 1/6 in mixed fraction case?(at 7:11). Thanks in advance!
16 2/3 is basically 16.666666 which is 1/6..see percentage videos
Is it the last video of SI CI ?
But sir says we will continue in next video 😐
Godddddddddddd level concept sir
These videos are enough for CAT? Or are there any other videos for CI and SI?
