Hello. I'm the tutor in this video. Since I'm unable to find any answers to some of the queries(common ones) below, I feel obliged to do it now. 1. Yes, 64/77 in a calculator is way easier. Unfortunately, it takes a considerable amount of time for people to solve manually during exams and under the stress of the ticking timer. 2. Yes, 39 is not a prime number. but it is semiprime, meaning it is the multiple of two primes (13 and 3). (Which anyways doesn't make it right.) 3. Apologies for talking too fast. It's in my nature that I run through words like a hot knife through butter. :P. It has sorta become like my identity. LOL. 4. WRT to the tricks in this video, I owe a lot to my peers and seniors at FACE. I merely collated them and presented them. Credits go to them also. 5. A lot of these tricks are not concrete. You can formulate your own also. For most of us that don't have the privilege of formulating our own tricks, these sure come in handy. Knowing these has never ruined me in anyway during exams, if not helped me outrightly. But, knowing them gave me a sense of confidence that I attempted more questions in Quants than I had expected. 6. At one place I got a little confused too when I listened to it now. Rookie mistake, perhaps. :P. Apologies once more. (I hadn't been training vigorously at that point. Might be because of a lack of touch. Still not an excuse.) [I tried to answer only the most common ones.] :P :D And this is my only video on this channel I guess with my face on it. You may find my voice in their courses, although it is very unlikely. WHEN THE VIDEO WAS UPLOADED I HAD NO CLUE IT WOULD GENERATE A 1000 EYEBALLS, LET ALONE 1.5 MILLION. I KNEW IT HAD HIT 1 MILLION WHEN MY EX-MANAGER CALLED UP TO INFORM. IT SURE FELT OUT OF THE WORLD. APOLOGIES IF MY VIDEO DIDN'T SATISFY YOU. THANKS FOR ALL THE KIND WORDS, APPRECIATION AND LOVE. THANKS, FACEPREP. MUCH LOVE.
Dear Bharath, Its really excellent; no doubt about it. You are genius as well as a good teacher. Just ignore some nonsense comments posted here, just continue your good work; all the best..
the second method(finding multiple or not) there u told that if we forgot the table then that method is usefull,,, but while solving ,,the method is expecting to remember the table,,,,,instead
Nice lesson, The last point is superb. I am facing difficulty in remembering those multiples. before, I don't know the concept behind that. Now, you made my job very easy. Thanks BDW, 39 is not a prime number!
You can also do it by Switching 77 by 64 like 77*64/100=49.28 And 64*77/100= 49.28 That can make the process a bit easier. And very easy in some cases. Like , Find 78%of 25. You can just switch it to 25%(1/4) of 78=19.5.
Why not just refer testing with the possible numbers to know the answer like, the first example 272 factor of 17 or not,focus on the last digit of 272 its 2,we just need to know the multiples of 7 the unit digit,In the multiples of 7 which one ends with a 2? We know its 6 as 7×6 =42,17×6 is obviously not 272 its 102 ,so try putting 17×16 and there you can understand doesn't trying out save time?
This is one of the best and simplest solution of these type of problems.Your are too good!! I would like to watch more videos of yours.I am a CAT and IIFT aspirant.
Ammmm,I wanna watch video of yours related to a few more topics in detail(%,Profit,Loss,C.P.,S.P.,S.I.,C.I.,Ratio,Proportions,TS&D).Can you please provide me the link,if there is any... I have tried hard to get that link but couldn't find the videos by same tutor. It would be my immense pleasure,if I get it asap... Regards, Shraddha
It simply a^2 2ab b^2(by squaring unit digit(b^2) take unit of result and pass remainder to left 2ab and so on) (b^2 unit place,2ab tens place,a^2 hundred place)starts from right!! square of any two digit number
Within a short span of time the lecture u delivered created an tremendous impact on me and made me to try the qa questions... As well... Tq so muchhh....
damn gooood!! the tricks are amazing and the variety of questions that you took were also extremely helpful!!! i was trying the question along with you and I was so surprised that the answers were correct in just such little time!
The method for finding 2 digit squares was amazing but the shortcut for 98² can be made simpler. Example 97² -- as usual last 2 numbers 3² = 09 And the first 2 numbers = 100 - ( 3 × 2 ) = 94 Answer is 9409 Likewise For 96² Last 2 numbers are (100-96)² = 4² = 16 First 2 numbers are 100 - ( 4×2) = 92 9216 is the answer . Thanks 😊
For that you need to understand the logic involved in it. It's all about the 2ab term. If we take 50 as base we can write 36sq. as (50-14)sq. Now, write down the expansion=> (2500-1400+196) you can see both the terms have 2 zeros in the end. This is reason why he subtracted 14 from 25. You can easily divide two two digits and arrive at answer easily. Now consider taking 40 as base, Write down expansion (1600-320+16) it will be difficult to calculate because of unequal number of zeros in the terms. Final verdict:- It is not that you cannot use 40 as base it's all about how simply you arrive at solution.

I need your brain in my exam tomorrow
Lol
Haha
You can be better than him
vjr prince ssmb pspk thank you for kind words hhhhh
U need to study more than this for implementing your idea
In this subscription channel only he got higher likes and comments.. And the way he explains is really clear to understand..
Very effective. Wish i had this when i was in grade school.
I just made it more easy. simply 64/100= 0.64. Then 0.64 x 77= 49.28. only one step multiplication required.
64 x 3/4= 48
.64 x 2= 1.28.
48+1.28= 49.28. Taadaa! 🤗
Great work dude¡¡ when u solved 1st problem i was lyk😧😳..i understood it very well
hi
All the information that you delivered were clear and easy to understand . Plz do continue your channel .
Veryyy veryyy effectively teaching in a very early....stage...keep a head sirrr have a successful journey....😀😀

problem solving is very very good..
thank you bro.. plz upload more videos on Quantitative aptitude
Make life easier and just multiply 0.77 by 64
considering use of calculator is restricted, multiplying 64 by 7 is pretty much tedious task
just multiply 77 and 64 using trick and divide by hundred
just multiply 77 to 64 then use ur brain after the answer 😂🤣🤣
No for Bigger numbers like 77% of 5987
Exactly😂😂😂
For some numbers it is difficult ......its better to follow (a+b)^2 form..........but u r teaching skills r great ........nd confident
You are looking in God mode, bro. Excellent command!!
You explanation doesn't allowed for confusions. I m happy with the teaching 👌
Its very cool bro the mathod of findingsquare was owsom
The square root method told by you is really too good
For some people it would be a very confusing. Because the explanation doesn't reflect smooth enough. Overall I appreciate and like it.
You speak aggressively but I like it this is good way of teaching
Oh my Days! Thank you so very much!
Squares technique is super amazing..THANKS A LOT
Your math's tricks are owesome. 👏👏👏

Please make more video For maths we always Support 😍😍
Superb video. It really helped, Thank you so much bro :)
If I had a good teacher like u in school days ..I would have been good at maths
Thank you so much
Now am getting something..thanks face prep
Well, you just nailed it.
"Correct"
Informative session.. this is what I searching for ✌️
You can also do it by
Switching 77 by 64 like
77*64/100=49.28
And 64*77/100= 49.28
That can make the process a bit easier.
And very easy in some cases.
Like ,
Find 78%of 25.
You can just switch it to
25%(1/4) of 78=19.5.
That was amazing. Thank you so much. I have an aptitude test for an FMCG company.I am very bad with math since childhood.
I hope ur dng a job now
Thank you very much for this video.thank you.thank you so much.

Fantastic bro, where u learned dis all tricks😊😊😊
IMPORTANT!
For the procedure @ 11:17
Bonus tip: Remember codes for few numbers such as 7, 13, 17, 19, 23
7 --> -2
13 --> +4
17 --> -5
19 --> +2
23 --> +7
Can you explain more on this codes?
Why not just refer testing with the possible numbers to know the answer like, the first example 272 factor of 17 or not,focus on the last digit of 272 its 2,we just need to know the multiples of 7 the unit digit,In the multiples of 7 which one ends with a 2?

Rule of Osculators---
Osculator of 7 is -2,
Osculator of 13 is +4,
Osculator of 17 is -5,
Osculator of 19 is +2,
Osculator of 23 is +7,
and so on.
Way of teaching is wonderful...and super😃 thank you so much😃
Very effective teaching skills!
Very clear and cleaver....Thank you so much sir.
What if we multiplied 0.77 to 64
I always take 1 percent and multiply it with what percent I want.
36^2=( 3/6)^2
3^2/2*3*6/6^2
9/36/36
9+3/6+3/6( means one digit in each)
1296 is ans.....it is (a+b)^2....thkuuuu

damn gooood!! the tricks are amazing and the variety of questions that you took were also extremely helpful!!!
i was trying the question along with you and I was so surprised that the answers were correct in just such little time!
(36)^2
= (40-4)^2
= 40^2- (2*40*4) + 4^2
= 1600 - 320 + 16
= 1296
hi
Its better to multiply 36 × 36
IT WILL TAKE MORE TIME FOR BIG EQUATIONS
superb my fantastic guru
Really ....... Helpful...... And ur English is very fluent ....plz upload videos like these.... And what's your name bro....?
Very Very Interesting , Thanks Thanks Thanks for above video
First que just make it simple 64×7×11/100= 49.28
You are good teacher , your explain way are super
The method for finding 2 digit squares was amazing but the shortcut for 98² can be made simpler.
Example 97² -- as usual last 2 numbers 3² = 09
And the first 2 numbers
= 100 - ( 3 × 2 ) = 94
Answer is 9409
Likewise
For 96² Last 2 numbers are
(100-96)² = 4² = 16
First 2 numbers are
100 - ( 4×2) = 92
9216 is the answer .
Thanks 😊
I also thought the same
Is 272 a multiple of 17 i am not understanding sir
Yes 272/17=16
It is same as : "Is 272 divisible by 17?"
Your English is too good bro
Young Energetic and crystal clear
Today I got the process from you. Very very thank you
Why have you not get the job with your skills🤔
He got job in face bro
lol , you could just write (1296/ 36*36) and divide the whole term by 12. No need to calculate square of 36. Nice session btw.
XD
What's his name? He explains very well and has a good style. Need more videos from him.
When taking 100 as power, then don't do half of it. Just substract the number (given in question) to the diviation. You will get first 2 digits
Thanks Bhai
why should we take base as 50 for 36 sqre? cant we take 40??
For that you need to understand the logic involved in it. It's all about the 2ab term. If we take 50 as base we can write 36sq. as (50-14)sq.
