Sir,l owe lot to you as because of you I am developing ability to approach question by properly phrasing it in terms of equation, condition and imagination...Thankyou Sir
Sir in question no. 7 ( 21:19 )- in third statement p+q = prime no. . Sir if I put 2 or 3 as prime and put 6 as composite no. Then total is 2+6=8 or 3+6= 9 which is again not prime. Then how the statement 3 is correct? May be there is word 'can' is used . that's why?.
Sir how is this possible also because we have to take Q as a composite no given in the question. So prime ×composite no can't be an odd no. Eq 3× 4 = 12
sum of digit is asked in ques . so , sum of 10 = 1 , sum of 100 = 1 , sum of 1000= 1 and so on . so for any positive whole no value of 'n' sum of DIGITS will be 2
Correction:
When a+b = 63 and a-b = 1
Then a = 31 (not 1) and b = 32.
That was a calculation mistake.
Plz rectify it
Sir ,if we take prime no 2 and composite no 4 ,we will get odd number ,you said directly by taking 11 and 9, why did you take that Sir ?
In the question it's said that can be word is used

Crisp and clear explanation.
Thank you sir.
Very helpful and enjoying the journey
can somebody please explain why did we calculate HCF in last que instead of LCM where it says minimum length ..
Thanku so much sir🎉
Very nice sir

It is due to word can. Had it been always - the statement would have become wrong. CAN DENOTES A POSSIBILITY HERE
@@civilserviceswithneelesh okay sir 😊🤍

Thank you sir 🙏🙂
Why in last question to find "minimum" length, we have are finding HCF and not LCM ? Samajh nahi aya..Plz explain
true even m confused with that part can somebody pls explain
And thank u very much sir for this amazing lecture ❤
Thankyou sir 🙏
Q. 4 nhi smjh aaya ...
Sir agar by chance Mujhe mere doubts clear karne ho toh main kahan se clear karoon
Sir k telegram channel pe
😊😊😊😊😊😊😊🎉
Sir Question 8 main 32×32 = 1024_1 = 1023 to option D answer hona chahiye
Yes
Here a is 31 b is 32 b²- a ² is equal to 1024 - 961 = 63
37
Questions Hindi me bhi type karke rakhiye sir
Will try
Ques no 8 में b की value 32 निकली तो a की value 31 होना चाहिए sir ना की 1
क्योंकि b+a=32+31=63
b-a=32-31=1
Plz check again & clear me.....
That is a calculation mistake. You are right
sir, you did last question wrong. answer should be 0.05ft
Check the official UPSC Answer Key. It is correct.
Q 12 nh smgh aya ....
Kisi ko aya to please explain 😊
sum of digit is asked in ques . so , sum of 10 = 1 , sum of 100 = 1 , sum of 1000= 1 and so on .
so for any positive whole no value of 'n' sum of DIGITS will be 2
Thank you very much sir 🙏
Thank you sir
Thanks sir ❤
Thank u so much sir
Thankyou so much sir 🙏🙏
