Respected Sir, The D.I.Y. Question at 4:10:14 has incorrect solution as the 2nd and 3rd case complies of 6! instead of 5!. The answer I am getting from my inspected calculation should be 550 instead of 1350.
How this man (respected sir) standing for more than 6hrs and teaching us with such patience and awesome concepts in high quality..GoD!hats off to your dedication sir..thanks is not just for your dedicated work and efforts ..you made fall in love with this chapter. 😊😁✌🙆💖
It takes true grit to take these classes. Standing and explaining for this long is miraculous. Thank You Sir❤️❤️🙏🙏 Thank You Atoms. Thank You Unacademy ❤️
@do u want to know my name ,check in description answer is 129(you forgot +1) in the solution you're looking at, it is taking all words where R doesn't come together

@do u want to know my name ,check in description iska answer to 129 aayega ,tumne 1 nhi add kiya hoga, and nta can sometimes be wrong ...okay brother..
I studied this chapter from physics wallah on paid course the content nv sir gave was exactly same including question plus he gave shortcuts so this is not less than paid course
Bhaiya Maine pahle kabhi permutations and combinations nahi padha hai. Kya is one shot video se mera concept clear ho jayega?????? Please help me bhaiya 🙏🙏🙏🙏🙏🙏🙏🙏 Or ye bhi bata degea ki NV SIR ke one shot video se mai class 11th ( which is wasted) ki tyari kar sakta hu. Maine class 11th me bahut saare lesson nahi padha hai Please help bhaiya 🙏🙏🙏🙏🙏🙏. It meant to me a lot
NV sir , Neha agarwal mam , pankaj sir , alakh sir , rajwant sir , Sachin sir , Monica mam ye sare teachers ek taraf aur pura RUclips + sari offline coaching ek taraf.❤❤❤❤❤❤❤❤❤❤
Trust me guys those who are gonna do this chapter for the first tym.....just blindly follow this lecture,,,,,it is the best on youtube,,,,,you will be pro in pnc ..... I have watched other lectures also but none was at this level which sir taught #nvarmy #iitpatna

At 4:10:32 sir aapne case 2 and 3 mai arrangement wqt 6! Kaise le liya word toh 5 hi ka bnana h n aur que 4:10:17 mai s 5 baar aara h par solution mai 4 baar ????????
As a senior let me help you by sharing my strategy. BTW I got 96% in12th Boards cbse and 4850 AIR in JEE MAINS 2023.... I can't believe how much joining a Telegram group for my JEE preparation transformed my studying experience! The resources shared and the constant support from fellow students were invaluable.I couldn't have done it without the group as it had imp previous year chapter wise questions... Although it was paid i bought it and trust me with the cheatsheets and daily dpp anyone can easily a score 125+
How can someone covered all concepts from basic to jee level in only a single one shot .... bhyiiii mza aa gya ab pyqs bhi saare aaram se ho rahe hai...
@@gamingop3891 Yes these lectures includes all the concepts, you would be fine if you follow these lectures along with other pyqs but there is any other latest 1 shot series by nv sir then follow that.
@it's me Nv sir's method is correct but you did not read the question right I think. They said excluding words that have two R's together so we should subtract those words.answer is 77
5:47:13 Sir we can even calculate any number with 25 in another method aswell !! Eg: 25x24 Then divide 24/4 then put two zeroes beside it Because 100/4 is 25 !! I hope u might understand 🙂👍🏻 If u want to multiply with 50 then half the number and put two zeroes to it !! I hope u like this trick !!
One of the best resouces for IIT JEE , a big thanks to nishant sir,sakshi mam and aall other unacademy plus teachers ,,,,personaly bounceback series which helped me crack this exam by fast track revisions helped alot thanks to the awsm team
3:46:49 i think there is correction in question 3rd`s answer when order of vowel`s same 13c6 should be divided by 3!*2! since in vowel there is repitation.
At 3:35:30 iss question me humne beggar coin method kyu use nahi kiya cause isme toh rooms same hai na so identical ko baatna hai non identical me so uss hisaab se toh beggar coin ise krna chahiye
Sir ne 4! Se multiply Kiya h mtlb rooms identical nhi h nhi to 1 se multiply krte And vese bhi agr example jb qn me 4 boys bola jata h to b1 b2 b3 b4 karke hi lete h sabko is hisaab se nhi Maan skte na ki sb humans h so identical Coin vala case me identical I think isliye shyd sb 1 rs ya 2 rs same rs ke coin honge😅 ye hoga sir ka mtlb
@@tanmaysachan bro I think whenever there isn't mentioned in question that the rooms or anything are identical, we should treat them as distinct objects.
@@amartyasingh7667 I agree. I know nothing about p and c and i just watched his lecture, and was able to solve adv 2007 and adv 2018 questions very easily . I was surprised lol
THANK YOU NV SIR FOR THIS AMAZING LECTURE . I WAS VERY CONFUSED IN THIS CHAPTER BUT NOW EVERY THING IS CRYSTAL CLEAR . NOW I AM VERY CONFIDENT ABOUT THIS CHAPTER . THANKS A LOT

Sir we can even calculate any number with 25 in another method aswell !!
Eg: 25x24
Then divide 24/4 then put two zeroes beside it
Because 100/4 is 25 !!
I hope u might understand 🙂👍🏻
