Gd afternoon sir
Ans is 8314
Sir first , second,third no add forth no automatically come
84 is correct becoz 14*2=28 14*3=42 14*4=56 here sequece is there but 14*6=84 is not sequentially
here digit sum satisfy becoz 381=12 ,552=12,903=12, and295=16 it is different of 3 one
19 no ans is 5467 and 20 is 383
Q19. All the digits are in increasing order but 5467 are not in ascending order so option(B) is correct.
Q20. 1st digit × 3rd digit = 2nd digit so option (C) is correct.
another method to solve Q19 is sum of first and last digit= sum of 2 and 3rd digit which is true in every case except for 5467
You both are great 👍
Ques.19-option B (5467)
add 2nd digit and 3rd digit=add 1st digit and 4th digit
Ques.20- Option C (383)
multiply 1st no. with last no.
y digit add nhi krne
sequence dekhna hai jo 5467 ka nhi bnta
2345, 3456, 5678 sequence me hein jaise 1234
What is rule of divisiblity?
.
@@Deepy.Bagri88 aapni apni marzi hai kuch bhi dekh skte hain... Jo phle ankho mai aaye
A option becz divide by 3
One of the best reasoning teacher on TH-cam..
Reasoning is equal to Halva bnane ke liye bahut bahut sukriya aapka sir 🙏🙏🇮🇳
19. b 5467 logic - numbers are arranged in random manner while the other options have numbers arranged in increasing order
20. c 383 logic - product of 1st and 3rd number is the middle one .
Sir jo 12th question h usme agr hm dusra logic lgae to ans alg aaega because all are divisible by 3 except 125
Yes, maine bhi yhi logic lagaya hai, and answer will be 125, aur odd even se priority me division pahale hai na, to uske according 125 hi hona chahiye answer
all option devide by 3 sirf 125 ko alg krke
Cube ki priority hai bhai
Divisibility rule 125 correct
Hm same
Question 12 according to me the answer came is 125 as all the others are divisible by 3 except 125...is this logic correct??
Sahi h
Kyu ki ham hamesha jo square hota hai usko prioritie dete hai
yes me vi yehi soch kr comment check kr rha tha
Unit digit
27=9
125=8
216=9
7+2+9=18=1+8=9
125 has different unit digit so answer will 125
125 hi answer aayega
Q 19 answer is 5467 as rest all numbers are in numerical order. Q20 answer is 383 as in rest of the numbers if we multiply the first and last digit we get the middle digit
Right❤
there's one more way to exclude option B in 19th question....
the sum of first and last digit is equal to the sum of the middle two digits.
q12) every number except 125 is divisible by 3, what to be done in that case ?
We have to follow the priority list
I've a doubt in question no 12
Que was 27, 125, 216, 729 you told that the odd one is 216 but on the other hand if see all the options all are divisible by 3 except 125 then the answer might change. Kindly reply
These numbers are cube as well as prime number
Priority is given to prime no. And cubes.
Neither 9 nor 6 os prime number so
The concept of prime number not use.
Sir aapki class approximate 15 min. Ke baad marketing ki add bahut aati h hume koi tarika bataye jisse aapki class start ho to koi bhi add na aaye or hum abhi 12th me isliye hum basic pad rhe h live class to hum nhi le skte ye advice hume mat dena sir or koi tarika pata g to hume bata dena sir appki class bahut bahut achi hoti h hum 👍👍👍👍 thank you sharing this video free on TH-cam 👍👍👍👍 like to banta h

Question 19 ( 2nd digit - 1st digit + 3rd Digit = 4th Digit)
Answer 5467
Question 20 ( 2nd Digit / 1st digit = 3rd digit)
Answer 383
19- B ( bcoz all nos are written in acending order form left to right except B option)
Q19) answer B(5467)
Q20) answer C(383)
1st and 3rd digits multiply we get 2nd number
Q19 = b) 5467 All other option's digit is in series
Q20 = c) 383 In all other multiplication of 1st and 3rd digit is middle digit)
Wahha 👏👏👏logic 🔥🔥
Sir in question no. 9 can we take digit sum. By taking digit sum A=12, B=10, C=6,& D=11, here 11 is odd number and all others are even number. Then option no. D is correct or not?
Question no 12
Ans would be b
Because rest of the no are divided by 3
Q12. As priority list, first come multiplication/division then come odd/even. Here all are divided by 3 except 125 which is first priority. Am I right?
19=B (not serialwise dight)
20=C (1st and 3rd digit multiple)
Question no. 12
All are divisible by 3 except option 2.. 😟?
@@taandavyt8826 usse relax nhi hota....pura din usme hi Jata h..per maine intsa preparation ke liye nhi delete kiya....mujhe addiction ho gya tha uska toh Kia
Sir..
Kuch question divisible se bhi solve ho jate hai..
And
Kuch question multiple se bhi..
Par answer dono ke alag ate hai..
Hame ye kaise pata chalega ki kon sa sahi hai...
Thanks for your help sir
*Question 19- Option B(5467) All other is consecutive numbers*
*Question 20- Option C(383) All other options are multiplied by first digit and last digit is middle number is answer*
consecutive number kiya h bhai 😂😂
19- b 5467 ....
20- c 383 1st×3rd = 2nd.. so.. thankyou sir
Can you check question no. 12
All are divisible by 3 except option 2 ?
Agar hum CGL ki prepararion zero se start kre with proper strategy then how many years does it take to crack SSC CGL EXAM (Both Tier)?
Q:20) (c)multiply 1st digit to last digit the middle digits matches all three option the stranger one is the answer
Solution : (a) 263, 2x3=6
(b) 482, 4x2=8
Answer (c) 383, 3x3=9
(d) 242, 2x2=4
for question number 16:
other logic is except 414 all others are not divisible by 3.
so correct answer is 414.
How to give priority?
392 is also not divisible by 3
Q.19- optionB 5467 & Q.20-optionC 383
20:41 ans: 140, (1st+3rd)-2nd =0
1+0-1=0
1+4-5=0
1+8-9=0
But 1+0-5 not equal to zero
Iss tarah v ho sakta hein sir
19. 5467 (digits are in ascending order in remaining options)
20. 383 (1st digit * 3rd digit = 2nd digit.....in all other options)
Q12 me 125 not divisible by 3 and 27, 216, 729 all are divisible by 3 isliye 125 answer kyu nhi aayega sir please reply
Your teaching Excellent sir 👏 👌
Sir 125 bhi ans ho sakta hai kyuki sabhi 3 se divisible hai
Sir u r grt....nd ur concepts are literally working..
H.w ka Answers ------
Q.19 ~b
Q.20~c ❤❤❤
Q19 B option is correct.
Q20 C option is correct.
Question 19
3+6-4 =5
Adding 1st and last no. -2nd no.=3rd no.✅✅
Question 20
Product of 1st and 3rd no. =2nd no.✅✅
2*3=6
19 B & 20 C correct✅ answer
Ans 19. B 5467 all options digit are in sequence bt option B digit are not in sequence so the ans. Is B
Ans 20. C 383 all options 1St and 3rd digit multiplication is middle digit bt not in case of option C
Maximum questions 2to 3 way ma solve hoty Hain....so Confusing!
Sir please provide your ssc cgl playlist link
Sir u are great teacher 🙏
Sir Q17 me answer 2709 hona chahiye ...kyuki woh no. 9 se divisible h baaki koi nhi ..... Aur priority list k hisab se bhi multiplication/division pehle aata h digital sum k
A of Q9 bcz all 3 are divisible by 7
Gd afternoon sir
110 = 1+0 = 1
154 = 4+ 1 = 5
198 = 1+ 8 = 9 pr sir 140 ko hum agr 1+0 = toh 1 ho raha jb 4 hota toh sahi hota
Thank you ❤️ Sir 😊
19 ka ans B
Sir in question 9 the last three options are divisible by 7 also so why we have to only check the divisibility by 4
Yes , according to priority list, we should give first priority to prime number which is 7 not 4, isn't it??
Question 12 me option B can also be correct because it is not divisible by 9.
Q19- 5467 as it is not in ascending order like the rest
Q20- 383
Sir 19=b, logic= sum of middle two digit and rest digit is equal
20=c, logic= multiplication of first and third digit is equal to middle digit
Q9) 84÷7=12, 28÷7=4, 42÷7=6, 56÷7=8........... Three are divisible by single digit but only option A is divisible by two digit..... So option A be also answer...... I'm I right sir 🙏🏻
Question no. 12 ka ansr B hoga bcoz
27 , 125 , 216 , 729 all are cube but 125 is not divisible by 3
Hmmm मुझे भी yhi lga था... But I think priority list के according है sir का answer, because direct divisibility से check kre.. तो 125 होगा... But agr priority list को check kre to cube पहले आता है...
Sir Q 12 =125 vi he .digit sum Karke ,if every 3 option sum multiple by 3 except 125
Sir 12th me aapne odd even ko divisibility se phle preference ku di
Sir homework ka answer 1 ka b hoga aur 2 ka c hoga
Sir may be the c is a answer of questions no:17 , because every series of digit number 3 is 1 except series c.
20 C 1st and 3rd multiplication is 2nd no.
Q No. 19
Answer ( b)
(A) 3+6=5+4
(B) 5+7 not equal to 4+6

Q 9 bcd all r divisible by 7 but not A option 84
Aise bhi ho sakta h sir but 🥺ans different aata h aapse mera 84 aapka 42 😟
q.17 pe agar hum opt 1 mein divsisble rule by 5 lagein to wo katt jayega pura 1315/5 but others nhi katenge to humara option priority ke hisab se A CORRECT hona chahiye tha??? If anyone have idea pls suggest to edit!
Q16 if we divide first digit with last two digits then we get remainder 2.
According to this D is right answer
Thanks sir
in question no 17. 2709 is a multiple of 3 and rest all are not then why you choose 8314?
19 num --- A (3 se divide)
20 num --- C (1st & last digit into × = middle term doesn't match)
No. 5, Option D bhi to ho sakta h. A. B. C. Divisible nhi h 3 se par D. Hai
Sir 19 ka ans 2345 addition=14 and 20. Ka 383=3×3=9but 8 here so 383 is odd one.
Option a correct.qsn no.13

Q20 c) 383
Ans.383
263= 2÷6=3
482=4÷8=2
242=2÷4=2
If we divide the first two digits of each numbers except optionC the remainder is the last No.
Ans. Is 9 ...multiply 1 digit and last digit
In one question 200,191,808,1331 according to cube 1331 is true but according to prime number 191 is correct . But books shows 1331 correct
Q:19) subtract 1st two digit with last two digits you will get the same answer all 3 option is 22.
Answer :-The stranger one is option (b)
Solution : a)56-34=22.
c)45-23=22
d)78-56=22
Q12. all are divisble by 3 but 125(B) is not divisble by 3 so why you apply odd/even before divisbilty check
Question 19 (answer is 5467)
Question 20 (answer is 383 )
Q19 option is b. 123456 concept
Q20 option is c. Divide concept

Jo ummid nhi kar ke dekho asan ho jata hai
Respected sir,
For Q.6) the sum of the individually A,B,C options is = 7 ....nd so the odd one out is 640 ....is this logic correct or not .. please comment...
How you can say that, bcz the digit sum of 350 is 8
Is there any special reason if yes then please reply and if noo then can't we take option A as our answer
Its a special class for hard worker students..
Q9
Digital sum 5+6=11 odd
ans=56
Other digit sum= even
Other option z they all are divisible by 2 except 56.... So answer is 56 ..... Sir is going on 4 .... We have to strt frm 2 nah if not eligibility then move to forwards.....
Sir Q-10 ka answer 552 bhi toh ho skta h ..... kyunki ye even number h baki odd numbers h
Q4, all numbere except 110 are divisible by 7
Sir 12 question ka answer 125 bhi aa skta h because all digit are divisble by 9
completed
Q 20 C part 1&last multiple in middle term
