Sir mai 11 mein hu mujhe ca ki padhai abhi se karni hai
Please sir can you tell me
Ham ca foundation May 2023 ka registration ye month me karvasakte hai kya?
I hope you ll answer my question.
@@MohdZaid-hx1dc kr skte ho bhai
mcq.35 ans is 64 bcz square root of 64 is 8, no other numbers in the sequence are having the perfect square root
Hmm ye ho skta h
Yes ❤
You are right 👍
35 question answer is 27 because
Compare the values of each other you will get prime number except 27 if you wana know try it
@@thakkarkush963what are you trying to say
Sir amazing explanation.....
On 38:28
The question is not wrong
It makes a pattern
Answer is
aabbaaaabbaa
Option (a) baa
It makes a pattern which is repeated itself i.e aabbaa
😮
Yup
Exactly
Yeaahh
For q 35 - answer could be 64 as it is the only perfect square
👍👍
exactly i was thinking the same
45:00 Sir, Q8 me 1:2 ka ratio follow ho rha hai(14:28, 20:40, 32:64) aur jo bada number hai wo apne baad jo chota number hai usse 8 jyada hai (28-20, 40-32). Isliye answer 56 hoga(64-8) aur 56 ke baad agar koi number hota toh wo 112 hota (1:2) ke ratio me.
You can use different logic to get same conclusion, bhaut ache
@@rahulbhutani_educator Ok Sir🙂
1:42:28 sir option b is correct because 64 is the only number who is perfect square.
Yes
True
Thanks bro
Anyone here who's attempt in dec 23
Me❤
Me also 😀
Me😂
What is your preparation leval guys
0
1:15:41 in Q23 fencing can also be the answer as all the other games requires ball to play whereas fencing does not..
Right or no??😮😮😮
No , Billiards is the correct answer.
1:42:07 Q 35
answer should be OPTION B because 64 is a PERFECT SQUARE NUMBER AND OTHERS ARE NOT ...... I Think...
I think it is right
Yes, u r absolutely right 👍
Anyone here who's September attempt
Yul
Yes 👋🏻
Jan25
1:17:49
9 will be the odd one out as 9 is composite number while others are prime numbers
Thanks for sharing MATHS, LR AND STATS Lecture But we do need more lectures of Accounts Please try to upload 3 to 4 videos in a week, it'll help us in improving in that particular chapter 🤞
yes
1:17:33=Q,25=(b),9
1:15:34 sir I think iska correct answer (D) Fencing hoga because it is a game of talwaar baaji while all other games are played with ball. So fencing is odd one among all .
Please reply sir 🙏❤️✨.
And also fencing is an indoor game
U r right bcz indoor criteria both fencing & billiards are indoor
Meanwhile me thinking Fencing matlab block karna kisi chiz ko (for security) 😝

Sir question 4 me option A hoga because letter series me hm last aur starting dono point ko leke chlte hai..... starting me aa hai so last me bhi double aa hoga uske bad last me doublr b hai so usse match krenge staarting ka aa k bad bb krenge
Sir in question 27 - answer could easily be taken as 4 because it is the only perfect square
Please suggest whether it is correct or not
1:25:39 sir according to me, only 4 is a perfect square amongst all the numbers. So the answer can be 4 as well right?
Ha yrr maine bhi yahi socha tha ☹️
Maine bhi
Only 4 is a single digit number number rest all are double or triple digit numbers
Yes bro
1:34:03
Sir iss question ka ek or method ho skta h
For the numerator---
Numerators are 3, 8 , 18 , __ , 78
As we can see from the first three numbers that we have to multiply the number by 2 first and then add 2 which will give 38 as answer
Eg: 3×2+2=8
For the denominator---
Denominators are 8,19,18, __78
We can see that the denominator is following a sequence too that is..first multiply by 2 and then add 3 which will give the answer as 85
For eg: 8×2+3=19
Hence, the answer will be 38/85
Bhai kya tum June 24 ke liye attempt de rhe ho ? ?
@@alokkedrawings ha
To aapka kitna syllabus complete ho gaya
Ye video enough h kya for this chapter
@@alokkedrawings ha video to enough he but or v questions practice krne honge...module ke examples v
1:41:10 ans is (b) because 64 is sq root of 8
Yes uh are correct✔
1:31:06 par sir difference ke 2 number ka addition next ka difference hai.
2+1=3
1+3=4
3+4=7
4+7=11
So, 7+11=18.
Hence 28+18=46.
Sir this is a much simpler method.
And sir u teach awesome thanks.
1:42:19=Q,35 ,sir 64 should be answer because 64 is also square of 8 , and remaining are only cube of the no.
Yes
But i think 125 is also a answer bcoz of only no. Divisible by 5 in this series
1:42:00 Ques no 35 ka answer hai B.64
Bcz of 8 is single digit no
27 2+7= 9 single digit no
64 6+4= 10 dobule digit number
216 2+1+6= 9 single digit no
Hence only 64 has dobule digit not by adding itself
Me bhi same try ki yahi Aya 64 is correct✔ ans
1:21:59 Sir when we divide all numbers by 8 so the all answers are in point expect 176 because it's answer is 22 so i think the odd one is 176.....And when we se that the 4 is one of the perfect square in this numbers so both are odds by their sides and you are also right by the pattern.... So sir Are many answers possible in one question??
Sir after this video i have cleared all concepts thank you so much sir for this free video lecture....it helps alot to self study...again thank you so much sir❤😇
Sir you are besr sir please hame blessed Karo ke hum CA foundation December 2022 ko 1st attempt mai clear kar sake🙏
❤️ , Keep studying bache and working hard , you will surely clear every level in first attempt
Thanks sir for your warm blessings I will surely do work hard and surely clear foundation in first attempt
@@rahulbhutani_educator thanks sir
Bhai Clear ho gya ?
@@caaspirant18_ mujhe b yhi jaan na h😅
In 1:42:17
Maybe 125 is odd man out as it is the only no. Which is divisible by 5....all others are not
Hence according to me the answer is (C) 125
ans is (b) because 64sq root of 8
Thanku so much sir for giving us really great lecture,,,,,,, thanku so much sir, you have converted every difficult topic easy......
❤️
Sir question (27) mai to 4 ho skta hai na kyuki wo perfect sqaure hai 2 ka baki koi v perfect square nhi hai
Sir in Q8 44:42 you can also solve it like
14*2-8 = 20
20*2-8 = 32
32*2-8 = 56
1:42:10=Given digits ka sum karte h toh 1 digit mai h but 64 ka sum karne pr 10 aata h jo 2 digit no.
Ans. 64
Question 34 it can be D also
coz X & 0 i got like the same way u did but if we see that another series is there
3+2=5 , 5+3=8, 8+4=12 therefore 12+5=17
so it can be option C also
Question 28
Ans :- EFMIJ(b)
Sir pleased add timed option in comments
Completed my maths from your awesome videos
Thank youuu
1:42:00 Given digits ka sum karte h toh 1 digit mai h but 64 ka sum karne pr 10 aata h jo 2 digit no.

@@rahulbhutani_educator Sir at 01:25:33 we can also see that only 4 is a perfect square nunber. So it is odd
But your logic is also right ur ans is 44.
So here we getting 2 answers. So how to select which one in exam?
Q27 - Ans is 44 becoz all other can be divided by its previous number
Question 25
Answer:-9(b)
Thank You Very Very Very Much My Dearest Sir 🙏🙏🙏
Sir aap question 7 main pehele +3 badme -2 karte ho to answer aa jayega
Check easy trick for series 👇
1:31:00 sir qsn no. 29 me agar gap dekhe tho 2,1,3,4,7,11 hai
2+1=3, 3+4=7, 7+11= 18,
Then 18+28 = 46 ans.
33:03 MSQ is the answer
1:50:07 D is the answer
Anyone from June attempt
Thank u sir
I am studying for dec23 attempt from Chanakya batch
Sir question number 27 mai answer 4 bhi toh ho sakta haa kyuki 4 he bas 2 ka perfect square haa baki sab number kisi ke square nahi haa ❤
Sir in Q. 27 4 is the prefect square and none of them are perfect square
1:23:57 answer should be 12 because all other numbers are not divisible by 3 (q-27)
38:22 sir your answer is wrong i guess as we can see the pattern is AAAABBAAAABBAAAABB SO THE OPTION A) BAA was correct
Is it right ??
1:25:10 sir iss question ka answer 4 hai.
Kyuki isake odd one out 4 hai, kyuki 4 he ek aisa number hai iss mein jo perfect square hai.
38:22 sir option A he sahi tha sayad....BAA✅ pattern dekho aap ( aab__ starting ke do similar hai matlab next b hoga to bb ho jayega......aaa__ ab isme bhi starting ke dono same mtlab __ me a jayega to AA ho jayega......bba__ isme bhi starting ke do similar hai mtlab aa ho jayega to final answer aya option a) BAA✅
Sir at 01:25:33 we can also see that only 4 is a perfect square nunber. So it is odd
But your logic is also right ur ans is 44.
So here we getting 2 answers. So how to select which one in exam?
exactly
Sir in Q.35 I think the odd number is 64 as it is square no. as well as cube no.
question 35:- ans 64 8 square rest of cube...8,27,125,216
Question 30 mai
Upper wala 3×2+2,8×2+2,aise bhi answer aayega
Aur lower wala 8×2+3,19×2+3 aise bhi answer aayega ☺️
37:38 the series might've aabbaaaabbaa
Opt a)
1:43:09
sir maybe the difference between no. is 19, 37, 61, 91
and difference of these are
18, 24, 30 which is devisible by 6 and 216 is the only no. divisible by 6 so maybe it is like that
Q23 the answer is fencing as it does not require ball to play billiards is not the correct answer as fencing is also an. indoor game
1:42:20 64 is perfect square
Yes
1:35:50 Sir in this question.. answer can also be 9. Coz 9 is also perfect square here
58:10=Q,15=(b)CPNCBZ
Question 35 answer is 64 because it having cube and square root also😉
sir in que no 26) there is another possibilities
15 is the only number which is divisible by 5 and others are not
MSQ is answer sir🎉
28 B
Q28 (B)
Q35 option B kyuki vo ek hi hai perfect square
Sir...in Alphabet series hum exam mai rough work ki jageh A to Z no. Likh k rakh skte nai na??
1:42:27 no.s alone ya summation ke bad 8 ya 9 aa rahe hai , 8 , 9[7+2] , 8[1+2+5], 9 [2+1+6] , only 64 is 10 here

Sir Esa bhi ho sakta h??
+3 then -2 again +3, -2, +3, -2
Ans. 10
1:40:52 sir I think iska correct answer 125 hai i.e option (C) beaches it is only no. which is divisible by 5 while others options are not divisible of 5 so 125 will be correct . Please reply sir 🙏❤️✨
Aise to 216 bhi ho skta hai only Divisible by 6 hai
@@sumankumarkartavyaslot1446 it is divisible by 2 also
I think it's 64 cause it's the only perfect square root.
See the options correctly u will not find 8 as a wrong if 125 is correct according to u bcz it is only the no which is divisible by 5 than why 8 is correct according to them
Q27 ka answer A)4 hona chahiye bcz 4 is a perfect square of 2
Q-35 answer is 125 because it is the only no. which is divisible by 5
SIR QUESTIONS NO.35 MAI KOI GALTI NHI HAI USKA ANSWER (B) 64 HOGA.
ANS - 64 IS ALSO A SQUARE OF 8.
Sir CA foundation may 2023 ke liye padh rhe hai. Sir enough hai na aapki class
Ha, enough h
Q.26=(c) 63 bhi ho skta h . Bcoz ye odd no. h. & Q.27 =(A) 4 ho skta h becoz ye 2 ka perfect square h .
In Q8 ek or trick tha sir 14×2=28 , 20×2=40 , 32×2=64
28 or 20 mai 8 ka farq 40 or 32 mai 8 ka farq mtlb 64-8 krne se answer ajayega and that's 56❤
Sir in Ques 30 of PYQs I got another pattern
Multiplying 1 no. With 2 and then +2 and so on
And the dinominator multiplying 1 no. With 2 and + 3
Thankyou sir
8 ka square 64 hoga. So 64 is odd man out
Thank you sir.. Complete revision ho gyi chapter ki finally
Sir q27 4,12,44,176,890 here odd one can be 4 because 4 is a perfect square
