One month ago l started following you and my confidence level in QA was zero.. l watched almost all ur sections and so so grateful to tell u that.. after each section l got something that really raised my confidence..never seen a tutor in youtube with this much effort and dedication till date... Thank you so much sir.. and so grateful to youtube also for recommending your channel... ☺️
It really means alot 😀 comments like this really motivates me to give my best 😀 this literally made my day ❤️ thankyou so much 😀
I think u r matilda
U r excellent sir i also took great confidence after watching your videos thank you so much sir
My maths went from 0 to 90 only cause of you & shantanu sir!! I score from 5-6 marks to 20+ without fail everytime now.
Have you got selected in banking exams now or not ?
Distance=constant
US DS
T 2a 1a
S 1a 2a
x= DS+US/2
6=3a/2
a=4
y= DS-US/2
= 8-4/2= 2km/hrs
Answer is 2 km/hr
Thanks Brow
What makes this teacher unique is the fact that he doesn't take $hit from students. While most of the other teachers waste time of students by reading live comments and talk with students. This teacher uses his time efficiently and does his work with utmost perfection. Hats off sir not even Gagan pratap sir could probably teach the concepts of mathematics like you do. Lots of love from Kerala♥️
Yes🥳
Delhi वाले maths टीचर फेंकते ज्यादा है और पढ़ाते कम हैं ।।।
I started with your complete arithmetic playlist on 1st dec 2021, I am so happy to say that my qt has improved so much! All thanks to you Sir. Your content is much better than my paid coaching. Ans of the hw question is 2kmph
Speed of current X kmph
D.s speed=6+x kmph
U.s speed = 6-X kmph
Y=a/6-x=2a/6+x
=2 kmph.
Dhanyabad sir😊
I have never seen a class which can beat this class in my life ❤️
Even being a MALAYALI (Kerala) I could understand all the stuffs that u teaching , so happy to tell you, I CAN'T THANK YOU ENOUGH 😘
HE IS NOT ONLY A TEACHER BUT ALSO A SHOWER OF CONFIDENCE WHICH IS OPEN TO EACH AND EVERYONE 😊
Hi.
True
Can u plz suggest m resources 😢
Answer 2km/hr
Mene is tarah kia
Distance is same so
(6-y)2t=(6+y)t ....d=s*t
After solving this y=2
Thank you sir for such a fruitful session.
Struggled with this topic from the last two days. Watched repeatedly videos from another channel to understand but couldn't. Switched to this video and understood at once. Thought of skipping this topic. Thank you so much sir for making everything look possible to solve within seconds. One formula and one concept made everything clear for me. 🤝

I never thought the poem would turn out to be BOAT and STREAM chapter related...

If I followed you regularly only for 6 months, definitely I will also become the wizards of maths like you.
Mind blowing 🤯

Sir following you since a month ago... Just to say u r best teacher I've ever seen in my life... No extra time pass.. Just being originality in your teaching is what makes you different from others... Hats off sir 🙏🙏🎩
we are blessed to follow this series for all the QUANT and completing the quant in very very LESS DURATION
Last answer:
Given speed, x= 6km/hr (in still water)
So, 6=(2a+a)/2
=> a = 4.
For y = (2×a-a)/2
=> y= (2×4-4)/2
=> y=2
I hope I'm correct....And thankyou so much sir, your tricks & concepts are really amazing.
By watching your videos I attempted 25 question in ibps clerk exam along with some arithmatic question. U r a great educator sir. I respect you from the bottom of my heart🙏🔥

Sir your video lectures are so amazing that a student like me who is average in maths since childhood can solve all types of questions that too with full confidence....Your each n every concept make the questions easier to solve.. Thank you so much sir for your dedicated Efforts 🙂
Sir
I downloaded all ur videos of one video one chapter....
It really helped me....
Thank you sir🙏🙏🙏🙏
Pleasure is all mine 😃😃 keep it up 😃👍
Sir, pata nahin aapko shukriya kaise kahein.
Honestly, my mathematical literacy was extremely poor. But I always thought I didn't have it in me & used to give up any maths related questions in entrance examinations.
What I was unaware of is that my "basics" were weak. Foundation hi nahin tha, toh building Kahan se khari hogi😄
One month ago, I stumbled across your channel but thought you'd also give 100 tricks & formulas like many other channels with million views, which honestly is useless for learners like me.
But you are the best teacher in mathematics I've came across. Every topic that I've covered here, made my concepts clearer than ever. I could actually put into use all the concepts to solve sums myself which is a big deal for me. THANK YOU, FOR EMPOWERING ME WITH CONFIDENCE. YOU ARE THE BEST TEACHER, & I MEAN IT! ❤️❤️
Waiting for this!! Thanks 😊
Yessssss
Pleasure is all mine 😃
2 is the ans.
Har bar mai arithmetic ke questions me se kuch questions ko exam me leave krta rha hu. Jisme ye topic bhi tha pr ab nahi leave hoga. 😃😃
Ty sir 🌼🌼🌼🌼
Pleasure is all mine brother ❤️keep it up 😃👍
Mindblowing session sir 🙏🙏🙏🥰 thank you sir for this amazing class
Out of all the boat and stream class in youtube ...i only understood this ..thank yu very much...great
dill jeet liye guru jiii👏👏👏👏❤❤❤
Keep learning ❤️
Sir last no. Pe
Man speed = 6kmph
Current speed = 2kmph
Downstream speed = 8kmph
Upstream speed = 4kmph
For the 30 up stream and 44 down stream type problem
We can take HCF of 44 and 55 is
11 as d.speed and we get on substitute in the identity we get
Up speed as 5 orally.
We may substitute these values
of 5 and 11 in the second identity
and if it satisfies we can conclude
X as 11+5)/2 and Y as 11-5)/2.
This is a retired bank employee from Hyderabad .
Any how I am happy that your
approach and method of teaching is far far the best.
I wish you all the best .
what a crystal clear concept u giving us .fabulous thanks
Pleasure is all mine 😃😃
Thank you so much Sir for the session. We are so lucky to have a mentor like you. Understood everything very well.
Pleasure is all mine 😁 thanx for this amazing compliment 😃
In the other 24,28 problem we can go for HCF of 24 and 30
we get up speed as 6 and on substituting we get d.speed as 14 we can continue in second
identity . I think this may be a little quicker and oral way of
solving. In this case we can also try for HCf 28 and 21 I e 7 it will not work out then try next multiple of 7 i.e 14 it will give the answer.
2km/hr i hope i am right. Your teaching skill is great i have started following you last week only but it seems you are among those best teachers available on youtube, who can easily make people understand the concepts....thank you.
It really means alot ❤️ pleasure is all mine 😃 keep learning 👍
Solution bata do kaise aaya 2 km /h .
@@dimpidubey8024
Upstream : Downstream= 2:1(time ratio)
we know T=D/S
Therefore speed is inversely proportional to time.
So ratio of speed will be a:2a(say)
X=3a/2 = 6 or,a=4
Y=a/2;Y=2(putting the value of a)
Or u can do... distance will be same.
So make 2 equation make both of them equal , u simply get 2km/hr value.
U.S. = D.S.
2(6-x) = 1(6+x)
Solve them u get x =2km/hr
Yeah I got same answer
constantly following your videos from last 3 days.. you are great sir
Sir,last 2 day achi for IBPS po... preparation ta karichi but still feeling nervous 🥺😊... Thanks for your guidance throughout the journey 🙏🙏🙏

Ans:-2 kmph
Thanks a lot for the session 💛😊
2km/hr, thank you for the session sir!

Video is excellent as always 🙂...
N ans is 2km\hr
Answer:2km/hr
Given that x= 6km/hr, y= ?
Ds= 2x
Us=x
Ds/Us= x+y/x-y
2/1= 6+y/6-y
y= 2km/hr..
Thank so much..
Very useful video...
The way you teach it's wonderful....
Speed of boat in upstream is 20km/hr
Speed of man in still water is 24km/hr
Speed of current is 4km /hr
From x, a=4
So, y=4/2
Y = 2km/hr
Was waiting for this from longg........ ☺😇😇😇

Bohot accha laga ye video ❤️❤️❤️
Sir your last question's answer is 2km/h
Thank you sir for this wonderful energetic session 😍
Nhi samj aya
x = 6
y = ?
T-> US : DS :: 2 : 1
S-> US : DS :: 1 : 2 (as T & S inversely proportional when D is constant)
Now, (6-y)/2 : (6+y)/2 = 1/2
=> y = 2km/h
Can't thank you enough sir . U r really good. I am struggling alot because of this chapter . Thanks alot ❤️
