I recently found this playlist from Shweta Mam's video. It's literally a goldmine for CAT aspirants.. better than paid classes..
Yeah bro
Literally it is ♥️🙏🏼
Mee too
Yes bro
@@vishnurajan7706 bhai waise questions kitne solve krne chahiye ek chapter ke upr quants me??
CAT one class charges over 500rs. But this guy is giving these lessons for free, not to mention the quality is same as any coaching class would provide. Hats off
15 people avg 48 = 15*48 =720kg, now 16 people as 1 joined , so 16 *49= 784 , diff = 64 kg (the person who joined)
dammn i also applied same concept ... hope it works in all the questions
Thanks for this concept
Good logic 👍😇
Good 👍
What if another person joins? 17+48 or 64+17?
@23:00 -- alternate
Avg weight without heavy student = 60 - 2 = 58 kgs
Therefore, Heavy student weight = 58 + (40 * 2) = 58 + 80 = 138 kgs
Highly underrated playlist.
I have gone through many but if you want crystal clear concepts, this is the best on internet
He makes maths so easy and interesting! The way he explains is so simple yet on point!
If you want crystal clear concepts, these are the best videos you can find on the internet! Period.
Never ever seen this kinda Fastest method with concept of average, when some one leave or join the group.. Great Sir..❤️
Directly landed on these videos from Shweta Mam videos.Really so helpful for CAT Aspirants.Initially I am very confused what to read and what not and also confus
ed due to large no of videos on youtube how to read them but these playlist are the solution of each question,And also a valuable things for those who can^t afford expensive coaching classes.Thanks alot SIR for providing these videos absolutely free of Cost.
Thank you for helping so many of us. We owe you a lot!
i dont know wht i would have done without you sir!!! very neatly explained ......
Found this series from sweta mams video , thnks to her ❤😊
shortcut for this questions is Avg + (increase or decrease in Avg X total new quantity) = 48 + ( 1 x 16 )= 64
You are a true saviour .A geniuse! Every level of student can understand your teachings.
Just extremely thankful for providing such quality & knowledgeable content for free!
Can't believe, this is such a good content for free!!. God bless you so much sir!
I am from an engineering background and consider myself to be good at quant and dilr, but Ravi sir has not only shown me how little I knew but helped me learn concepts and tricks very easily. Kudos to you and your team sir. Blessing in disguise❤.
27:04 Sir I can guarantee this moment changed many things for hundreds of students....
YOU DONT HAVE TO WRITE, TO GET IT RIGHT...a true example; every teacher just says it or just do half of the que orally
This will gonna help a lot of people, very nicely and easily explained series. Thankyou very much Sir!
Sir, you make me feel like teaching is also an art.. Neatly Explained thanks...
Avg = Total weight of 15 students/ 15
Let total weight of 15 students be T
SO, it is given initial Avg = 48
Therefore ,
48 = T/15
So, T = 720
Now when 16 th person joins avg weight inc. by 1 and becomes 49
Similarly , we can write
Avg = Total weight of weight of 16 students/16
OR
Avg =
(Total weight of 15 students+ weight of 16th student) / 16
Let weight of 16th person be x
Now,
(T+x)/16 = 49
Keeping value of T from above
x = 64
Much more straight!🤌🏻💯
time taking
This method is logical and straightforward too, but Ravi Sir's method can be done without even taking pen and paper, so that would be better in the long run
Thank you sir for the wonderful videos❤️ Your channel deserves much popularity🙏
Amazing channel started my prep last week and its helped so much.

Well done.. thankyou 🙏🙏
sir in 13:22 question. In these questions like these i use the method as =new avg weight(49) + {increase in weight(1) * no. of people in initial stage(15)}= 64. Is it correct??
Great thanks sir!
Salute to your all great efforts of explaining concepts so beautifully...
Using small brush for indicating no. and then switching to color pen repeatedly with so patience....

Thank you so much sir to cede this miracle to us.
where do I find the practice questions?
In cat 2018 ,"there was a question that a cat aspirant appeared for a certain number of tests .his average score increased by 1 if first 10 tests are not considered....." .so can we do this question orally and if yes then by which method????
Awesome questions sir thank you
Is that all questions are from CAT exam's paper ??
THAANKS ALOT SIE! FOR tHESE BEAUTIFUL CONCEPTS!😇

Bhagwan lambi aayu de aapko 🙌🏻
Dhanyawad Prabhu ❤️
If the average weight of a group of 15 friends is increased by 1 kg when a person joins then why should we add the 16th one ? I think it should be like 48+ 15×1 = 63 . Please someone explain me .
Very useful shortcut sir
excellent content
solved it in within 15 sec. Damn sir you are good.
Sir in first question why you cannot apply first +last divided 2 formula?
It's not in a.p.
Is your da section enough for cat? I m just depending on your videos for my preparation...plz guide....
Yes very helpful
The average marks of a class of 33 students, increases
by 3, when three of them leave the group. If the average marks of these three students is 1/4
average marks of the original 33, then the average marks of the remaining 30 students is?
Please help in this question @raviprakash sir
Thanks a lot sir 💓
Tq @shweta arora diii fr this excel sheet
Helping a lot sir ❤❤
Nice explanation sir....
Thank you. If you like the channel please share among the friends who are preparing for CAT exam
Thanku sir for ur valuable videos..
Can anyone just let me know that why we r assuming that all students weighs 50 kg , if avg. weight of 15 students is 50 kg...??
1:36 here can anyone explain me why we changed to 1+11+....... insted of doing 9+99+999+.....
Please let me know this
Sir , Is this useful for Banking Exams
thankyou so much sir for your hardwork
At the time of joining of one people we are adding +1 to that people also so at the time of removing one people why we are not removing -1 or -2 (according to the problem) from that people
01:35 can anybody please tell me why Ravi sir chose 1 + 11 + 111 and so on instead of adding 9 + 99 + 999 and so on to find the average number?
9 was taken as common from the numerator and got cancelled by the 9 present in the denominater
am i wrong for doing it like 1+15/2=8, so the 8th friend has 48kg weight. so when 16th friend comes 1+16/2=8.5 and 8.5th friends weight becomes 49 since 8.5 doesn't come when we count from 1 to 15 so this becomes a pattern like 8th=48 8.5th=49 9th=50, which eventually tells us that 16th friend's weight is 64.
thankyou sir and Shweta Arora ma'am.
Amazing Session Sir 🙏
