Sir, for question no:7. what is the need for such lengthy equations?. u already told that "product of two number = LCM*HCF" Let the numbers be x and y. so we get x*y=24 and x-y=2. just need to check which answer option satisfies both conditions. simple :)
Sorry to be off topic but does anyone know of a way to get back into an Instagram account..? I stupidly forgot my account password. I would love any tips you can give me.
For Q 10 give any numbers to X&Y and find the HCF and then give the same numbers to the option and cross verify the HCF If X=2 Y=1 eq1=28 eq2=4 HCF of 28 & 4 is 4 Give same values to every option Ans will be opt A
Sir i love the way u teach the question no 10 i am soo impressed and it give me a lesson that i have to try a lot to get answer and don't give up easily
sir mera 2 problem ka solution chahiye 1 if a381 is divisible by11 find value of smallest natural number 2 if 381A is divisible by9 find value of smallest natural number
A can do a particular work in 6 days. B can do the same work in 8 days. A and B signed to do it for Rs 3200. They complete the work in 3days with the help of C. How much is to be paid to C?
Really we are hat's off to you for your valuable questions and Short cut answer. Thank you so much for teaching to us and it will use for us.pls continue sir.gd nt nd sdrms
Always remember jabhi bhi 1) find smallest/least/minimum number ase question aya to . Solution :: unka direct LCM find karna or jo difference he o subtract krna padta he LCM me se. Or , similarly jab bhi 2) find latgest/ Maximum/highest number asa question aya to tab . Solution :: Directly HCF find krna or jo reminder usee firstly subtract krna
For the numbers with same bases, the number with highest degree is LCM and number with lowest degree is HCF... in your question 7^2 is with highest degree, it's LCM and 7^-4 is HCF
😴😴😴😴 question 7 is so lengthy sir....just go through with short trick... The question is product of two number is 24 and there difference is 2. Means just multiply the number which is given in option which give 24 and difference is 2... 6*4=24 & 6-4=2 thats all.
Exactly same dout lcm 12 aa raha he . Wo question co-prime factor se solve ho sakta he or option A) 8,6 statisfy hoga or option A ka LCM bhi 24 Aa raha he

Yeah your right bro....
Yes brother you are absolutely right because in such exams a candidate is mainly provided with a a very small period of time to solve 1 question.
Left = right common ansr....so take this way to aproch....
And sir plz check this question
you aaply the formula in this question
(x-y)² =x²+y²-4xy
Check this plzzz

For Q 10 give any numbers to X&Y and find the HCF and then give the same numbers to the option and cross verify the HCF
If X=2 Y=1
eq1=28
eq2=4
HCF of 28 & 4 is 4
Give same values to every option
Ans will be opt A
Bohot achhi class thi sir ye.. :) Muje Vidya Guru ke reasoning videos bhi kafi pasand hai. Unka karaya kafi exams me aa jata hai.
Que5. To find lcm we have to take common numbers and its biggest power. But here 5and 7 is not common.
Answer will come 2^3×3^5.
Is it right
Question no 7:- xy =24 then x=24/y , put x= 24/y in equation 2 so 24/y - y = 2 if we solve it we get y =4 and put it in equation 1 we get x= 6
Can u explain it clear ly plz
Shambhu Singh chu hai kya?
Lengthy rule for competitive exam..it is not a board exam
It was very useful.
Que7. Simple ans by checking options we get.
Dont need this much lengthy solution
Great lecture but short ways bhi hein is main question 7 main hcf * lcm easily answer ajaye ha. But very good lecture

Q .7 wrong option he sir 6,4 ka lcm 12 aa raha he .
Option A) is correct unka LCM 24 aa raha he or wo condition bhi statisfy ho rahi he
Sir it takes a lot of time..
i hv a doubt in qus no 9 ...how comes 15120-10 pls bro pls xplain it
yes i have also same doubt ,if we lcm for those number i get 30240 please explain
Mammu Rama Lcm is 15120...recalculate
Always remember jabhi bhi
1) find smallest/least/minimum number ase question aya to .
Solution :: unka direct LCM find karna or jo difference he o subtract krna padta he LCM me se.
Or , similarly
jab bhi
2) find latgest/ Maximum/highest number asa question aya to tab .
Solution :: Directly HCF find krna or jo reminder usee firstly subtract krna
Q10 also takes a lot of time
q12. ans: 0.9
Thank you.. sir..
Does'nt need such a lengthy method in questn no.7..
In the problem 4 why we are adding 1
Same que is mine!!!

We add 1 in final answer becoz, at initial bells ring then next countdown we start & hence therefore so, we add 1 in it.

Sir please explain 2018 group d rrb. Mathes
super sir gee
sir in 12th question GCD is the hcf not a lcm sir
Sir ye apne question bataya he bo sach me rrb group d ke question he ??
Good
if we have numbers whose degree is negative then how will we find hcf and lcm.
7^(-2),7^(2),7^(-4)
For the numbers with same bases, the number with highest degree is LCM and number with lowest degree is HCF... in your question 7^2 is with highest degree, it's LCM and 7^-4 is HCF
Why we add 1 in question no 4
S....same doubt

Bhai Pure 1 Hour me 1 Hi Question nhii karna hume.. 😕😕😬
See option... d).their product is 24,difference is 2
haha..he is teaching for aptitude descriptive exam i think so
You can actually do it less than 10 seconds as *product of two numbers is product of their LCM and HCF* now see options only d follows

7 th. quistion....lcm of 4, 6 is not 24 its 12
Let one no -x
Second no -x+2
Henxe x(x+2)=24
X^2 +2x -24=0
Ab kr lo solv
Exactly same dout lcm 12 aa raha he . Wo question co-prime factor se solve ho sakta he or option A) 8,6 statisfy hoga or option A ka LCM bhi 24 Aa raha he
4 question y we have to add 1
Same question
Actually bells started together first, then toll at interval of 6, 7, 8, 9 seconds. So 1 is added
We add 1 in final answer becoz, at initial bells ring then next countdown we start & hence therefore so, we add 1 in it.
