Amazing lecture sir☺☺i was weak at maths but just because of you My maths is improving day by day ❤.. Thanks for the Good work.. keep it up sir.. May Good Bless you with higher level of success in life ❤❤❤❤
Answer to question 4 is wrong i think. I feel Answer is 1440, Since no Two vowels are together, vowels can only be placed in this way. V_V_V_V_V Since there are 5 vowels, and 9 letters, any other formation will violate the rule. In the 4 blanks the remaining consonants will go. I repeated twice, hence divided by 2. 5*4*4*3*3*2*2*1*1 / 2 2880/2 = 1440
27:17 this method is not correct because in all vowels we count them together not particular 2 or 3 vowels(there is chance two or three vowels come together in 4or 5 vowels in the word )and this question never come together wala they will never come together
25:00 Q4 vowels not come together 28:00 Q5 vowels not come together 28:00 Q6 vowels with start and end (answer sahi h, crosscheck kar liya mene) ""concept clearity""
Q.2 Ans 4 digit numbers= 7!/(7-4)! = 7!/3! = 840 Total 4-digit numbers are 840 which includes also those numbers having 0 as most left digit like 0134, 0479 etc which can be written as 132 and 479 which are not 4 digit numbers. Therefore we will first calculate total number of 4 digit numbers which have 0 as most left digit.when fixing 0 as most left digit then there leftovers only 6 digits which can swap there places and we now need to take only 3 digits at a time, we therefore do calculations as follows; Number of 4 digital numbers having 0 as most left digit= 6!/(6-3)! = 6!/3! = 120 Valuable 4 -digit numbers= 840-120=720
24:00...lekin vowels 2,2 karke bhi toh aa sakte hay! kiuki waha yeaa kaha mention hay ki sab vowel ko ek saath nehi ana hay...matlab socho pehle EA ek saath aya...uske baad consonants ...toh fir yeaa toh galat ho jaega.

excellent explaination... just had a doubt, 8th question mein last mein 5! kyu nai aaya(1,3,5,7,9) bhi aapas mein position exchange kr skte hain na?? SIr please explain... baki sb smhj aa ga... thank you:)
Bhai mere jab last me place hi ek h to tum 5 thing ko kaise arrange karoge 5p1 karoge jiska value 5 hi hota h. In brefiely- 9*10*10*10*(1)=9000 9*10*10*10*(3)=9000 9*10*10*10*(5)=9000 9*10*10*10*(7)=9000 9*10*10*10*(9)=9000 =45000
In Q)3 evens case total numbers including 0 are 7 ,since 0cant be first one is taken out so 6 and even number is at edge so -1 the. 5×4×3 In case of Q)8 odd numbers including 0 there are 10numbers so 10-1 = 9 If repetition is not allowed 9-1(odd number at unit's place) can be done? Then 8×7...
Sir jab hum nay even waley question karey tab hum nay aur method lagaya aur question number 7 may odd waley may app nay aur koi method use kiya ...question may bool raha hai woh odd digits number kitnay form hongay

V_V_V_V_V

I repeated twice, hence divided by 2.
5*4*4*3*3*2*2*1*1 / 2
2880/2 = 1440
You are right
Is there a purpose for repetition
Can't we write 5!×4!/2!

Q.2 Ans
4 digit numbers= 7!/(7-4)! = 7!/3! = 840
Total 4-digit numbers are 840 which includes also those numbers having 0 as most left digit like 0134, 0479 etc which can be written as 132 and 479 which are not 4 digit numbers. Therefore we will first calculate total number of 4 digit numbers which have 0 as most left digit.when fixing 0 as most left digit then there leftovers only 6 digits which can swap there places and we now need to take only 3 digits at a time, we therefore do calculations as follows;
Number of 4 digital numbers having 0 as most left digit= 6!/(6-3)! = 6!/3! = 120
Valuable 4 -digit numbers= 840-120=720
Isn’t Q8 wrong ??

Amazing sir
Sir DI class ki video kaha gayi
excellent explaination... just had a doubt, 8th question mein last mein 5! kyu nai aaya(1,3,5,7,9) bhi aapas mein position exchange kr skte hain na?? SIr please explain... baki sb smhj aa ga... thank you:)
Bhai mere jab last me place hi ek h to tum 5 thing ko kaise arrange karoge 5p1 karoge jiska value 5 hi hota h.
In brefiely- 9*10*10*10*(1)=9000
9*10*10*10*(3)=9000
9*10*10*10*(5)=9000
9*10*10*10*(7)=9000
9*10*10*10*(9)=9000
=45000
Very nice sir
Thank very well explained
In Q)3 evens case total numbers including 0 are 7 ,since 0cant be first one is taken out so 6 and even number is at edge so -1 the. 5×4×3
In case of Q)8 odd numbers including 0 there are 10numbers so 10-1 = 9
If repetition is not allowed 9-1(odd number at unit's place) can be done? Then 8×7...
I guess Q8 ans would be 29160 and not the 45000.
very nice
