I always recommend FFL for all my friends.. because your teaching way is entirely different from other faculties. There are many lectures in RU-vid but they all took classes in Hindi but FFL provide as good class with English.. Thank you sir
Ur words r true I don't like competitive exams but by seeing FFL Sathish sir's video I feel confident to study bcz he is teaching difficult topics in easy way and first he has learned the topic well bcz one can teach others if he is 100 % clear in what he learnt then only he can teach others very well and sir we r expecting more videos clearly
Hi everyone I observed one thing in this video that sir forgot to say about divisibility rule of 16 or the clip might be missing. So I want to mention it here The divisibility rule of 16 is Add last 2 digits to 4 times the rest. The result must be divided by 16. Eg: 176 ==> 76+(1*4) ==>80/16=5 So the given no. is divisible by 16. Hope this is useful
And it is to be noted that, for number 11, divisibility rule is, the difference between the addition of odd-placed digits and the addition of even-placed digits should be either zero or should be divisible by 11. For eg: the number 2804857 whose difference becomes zero when the said rule is applied.
@@shaikmuzaffar4895 It's not odd and even numbers, it's odd digits and even digits . That is 1st + 3rd + 5th is odd digits and 2nd + 4th + 6th digits are even.
@@shaikmuzaffar4895 No, it is not about odd or even digits, it is about their position: odd placed digits (9, 7) and even placed digits (1, 4) so 16 ~ 5 = 11, and 11 is divisible by 11, so '9174' is divisible by 11.
Such an amazing explanation i have been your follower since last 3 years i always came back to you channel whenever i get a doubt in quantitative aptitude may god always bless you sir❤️
Awesome teaching sir 🙏Even in skl they haven't taught the divisibility rule so clearly for these many numbers..this would be of great help in the exams for faster calculation...no words to thank u enough 🙏
Tbh you're the first maths teacher whose teaching i can grasp it easily. I used to almost byheart and solved maths during my high school days but now im able to understand the concept clearly from your simple yet meticulous explaination. Thankyou so much🎉
Tis guy is too good... he makes the toughest problem so easy to understand... really God gifted... one of the best videos on RU-vid 4r competitive exams... God bless n continue d gd wrk as many students who are weak in math are beginning to like math the way u teach it... too gd...
The best ever teaching teacher I have ever seen, your explanation is to so easy to understand. Thankyou so much Sir, it will really help me in my upcoming competitive exam😊😊 . Look forward the other lesson👀👀👀
Love you lot sir , wonderful and very excellent section . I will definitely introduce it to my friends also , who are all preparing for competitive exam.
I am very lucky to find this channel . I don't find any maths classes in english medium. Thank u so much sir. U help me a lot for my ssc cgl preparation.
1 is even number you are right but in the video teacher is talking about the order of digits like number is 6006 then 6 is 1st , 0 is 2nd , 0 is 3rd , and 6 is 4th . Now take 1st and 3rd because both are odd and 2nd and 4th because both are even and calculate the answer.... 😀
Sir your teaching is easy to understand....i was so down in math during my time till now but after watching your video now i know that the problem is not me but its the teacher who can teach and reach the mind to make them understand and that quality and special teacher is you......long live sir
I recommend your classes to my sister too i m preparing for upsc ,your classes are awesome sir 🙏🙏and i feel like you talk in hindi but you r talk in english its easy to understand the way you talk in english ,keep it up sir
Odd digit places add Karo like I take one number this example....2453 = 2+5 =7(this odd places ) 4+3=7 (this even number place )next 7-7=0 so this divible by 11
Sir U r lecture is undoubtedly superb but here is my suggestion can U pls able to upload aptitude and Reasoning complete marathon video because everyone in comment section wants that.No RU-vidr have uploaded aptitude and Reasoning quality content as u did....
Thank you so much sir....,🙏🙏 The way u teaching n English just awesome .....an average student can also learn easily from u... & I always recommend FFL to my frnds...Or I can say this is our channel....
Hi sir actually I need your help sir I need quentitative aptitude practice questions in pdf format and general English topics and you please suggest fully cover text book in (english) sir..
Thank you soo much I am really thankful for you as I understood very well . Your teaching way is very nice I liked it alot and it's very helpful for me and once again thank you soo much.
@@FeelFreetoLearn sir devicibility rule for 11 is confusing, is that is odd degit or odd placed digit and one more devicibility for 16 is missing please clarify sir, thank you
Hi Sir i really like your teaching and i understand the concept easily thank you and i would love to purchased if you have pendrive course for Banking exam. And again Thanks Alot
Very glad to text you sir. Please make video for Combina defense service examination (CDS) it connecting by UPSE. It will use full for million people in our country and especially our TN people It only basic elementary mathematics topic like 1. 💥Area and perimeter plane figure* 2. 💥Surface area and volume of solisolid 3. 💥Measurement of angle and trigonometric ratio 4. Triangle 5. Circle 6. Statistics 7. Algebric operation 8. Quadratic equation and inequality 9. Number system 10. Square root and cube root 11. Time and distance 12. Simple interest compound interest Ect...... Please make in tamil medium and english sir 🙏 Important topics in elementary basic mathematics 6th to 10th level. Sir thank you so much 😊❤. Please reply sir.
Digit 11 rule When sum of odd digits and sum of even digits is same When we find difference by subtracting it will come 0 And then divide it by 11 i.e. 0/11 How we can do that Check on example as 613533333325 it's divisible be 11 how? By using this 11 divisibility rule
Divisible by 16 is complicated. Suppose, if the last four digit is divisible by 16 the whole number can be divided by 16. If the number are only three digit, it is very difficult to know. 😄😄
Last 4 digit means maximum digits we have to take for larger number. if it is 3 or 2 digit we can directly /by 16 for eg 32,two digit number it is /by 16.
Sir ur classes are so better and better than all other youtubers 🙏🙏🙏tqs aaaa lot for supporting us sir u have any pendrive classes tell us we will buy and become IAS😂
Divisibility rule 16 If the thousands digit is even, the number formed by the last three digits must be divisible by 16. ... If the thousands digit is odd, the number formed by the last three digits plus 8 must be divisible by 16. Example: 3408: 408 + 8 = 416.
Sir in divisibility rule of 11 you said 6 is odd no..which is wrong plzz check 😭,And also during adding 9174 you add 9 & 7 as odd which right but then you add 1 & 4 to saying 1 is odd which not Right 😭
