[@mayursikhabordoloi795]

Honestly speaking sir, permutation and combination has always scared the hell out of me. I thought I would never be able to understand the concept and therefore preferred skipping this portion. But beleive me, after watching your classes, I can't believe even I am able to solve the questions. I will be forever grateful to you sir. Your classes has made my upsc csat preperation very smooth. Thank you so much sir, Dil se ❤️🙏

I have watched various permutation and combination videos of different channels and faculties but could not clear by foundation/ base. Was not able to solve any questions as well. But, but tbh your lecture/ video has changed my perception and removed my fear of permutation. Thank You!

Homework:- 4 digital, 9 latter 7×6×5×4= 840 _ _ _ _

[@faizanahmad5201]

In question no. 5, why do we count 'o' twice, when we have already fixed it's position at ist place? Like in question 4, we exclude 'c' from counting as it's place is fixed. So why not in question 5.

[@minalmittal7856]

I have same query. Did not understand this point

[@aditikumari2860]

Bcz only fst place is fixed.... Still there are 8 places to be arranged nd there are 2 O in the word CHOCOLATE so only one O can be placed at fst position

[@garvitsharma4464]

Waise to ye solution dekhe to glt to hai but jaise inhone or solutions me bataya ki saare vowels ko ek box me daal denge or use phle 1 manege or phir bache hue words ko count krege to 6! Honge ( sir ne 8! Likhe hai 🤔) @aada247

U r great sir

[@SD1234-CS]

In this lecture when you are talking about question no 7 ( LUCKNOW , Vowels come together ) So here , I fix 1st two places for two vowel ..... and number of remaining letter is 5 ..... so the no of arrangements of two vowels in two places is - 2! .... and the no of arrangements of remaining 5 letters in 5 places - 5! ..... and in this way the result which I get is - 2! × 5! = 240.... But your method gives the result - 1440.... Why is this difference?

[@HaarisShah]

It’s because, [u|o] (1)can also be rearranged with remaining letters (5), therefore we take 6! and multiply it with 2P1 as U/O can be rearranged between each other.

[@SD1234-CS]

@@HaarisShah yah yah got it.... Actually I thought all possible words start with vowel ... and all vowels ( if exist) come together, ,,,, Thank you

[@preetirawat485]

I have the same doubt 🤔🤔🤔
