@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

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+

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 !!

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...
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+

thank you so much sir...mast revision ho gaya and naye tricks bhi mil gaye!
Hats off to you sir
Very helpful lecture for revision
ty so much sir
Thank you so much sir
He has really nailed it ❤
Real way of finding rank of word is way better than trick, 💕💕
sir u r just awesome brilliant marvellous and even words are less to describe u......
kyy teacher ho sirr aap.....sir ur brilliant u used to give v crystal clear concepts
Are these lec enough for those who are studying this chapter for the first time
At 4:10:36 the ans is coming out to be 550
Mine too. They wrote 6! Instead of writing 5! while making cases
@@ayushmishra6687 bro ek S extra hai word mai usko thik karo fhir ans thik ayega
Sir ke answer mai S = 4 hai
This lecture is enough for jee mains or not plz tell me anybody?
It is enough 💀 cbse doesn't have this much of portions lol..
Sir I m in love with maths 😊 just because of u thank you 😊😇❤️💛🧡♥️💖☺️🙏
Tq very much sir ❤❤❤❤
thank you so much sir for this platinum level diamond content.

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 !!
THANK YOU SO MUCH SIR 💙💙💚💚💖
got the full feel thanku so much sir
Thank you sir for this amazing session😍❤
Is this sufficient for beginners?

I literally mean U are the best teacher of Mathematics.
No no take this comment seriously .
I mean its WOW. In jst 1 shot we r doing everything, literally everything from basics to advanced PYQ's man.
Hats of to your dedication man.
I mean this couple is god made as man they both teach Perfect I mean PERFECT. Love u both......
the ongoing BB 2.0 isnt good for someone who havent studied these chapters right?
@@atharvsharma1866 tHEY HAVE CONVERTED IT INTO bb SPRINT so I think if you have less time u can go for that but if you have a lot time then def prefer bb orignal.
Everything isnt much covered in bb2.0
@@fifamasters6184 but the BB sprint doesnt cover theory properly its just a quick revision. i havent studied some chapters even once so thats why xD .
@@atharvsharma1866 hope you got them covered now xd
@@fifamasters6184 yep finally done.
