For 5th question just use average speeed=upsream*downstream/speed in still water. Apply the averag speed in formula spees=dist/time. U will get 4.8 as answer. Divide it by two. 2.4 km is the answer
The question where to find the rate of the stream in which speed of boat is 18 and DS is thrice of UP can be solved simply by the following: => 18+X= 3(18-X) , where X is the speed of stream resulting 9km/hr.
In the question where how far is place is ask. I think distance should be half of 2.4km . because in upstream and downstream same distance travelled in two times. Isn't it?
A Boat going upstream takes 8 hours 24 minutes to cover a certain distance, while it takes 5 hours to cover 5/7 of the same distance running downstream. Then what is the ratio of the speed of boat to speed of water current? solution please
Leave that point itself Just check your options if it is in m/s or Km/hr and take the next steps accordingly. As this pattern is more often in govt exams you have to be in this way.
Hi this is sai miss @Ieshwariya garu whatever you explained is nice but i didn't understand because the way telling the point is not that much of impact or not reaching and not understanding try to give a proper way of explanation about the concept
Ishwarya mam u look so lovely.Thanks for teaching.Its easy to understand.
Nothing but your concept is awesome 👌
lol
Mam you are back again wow!!!!!!! I love the way you teach mam 😍😍
This lecture is nothing but a blessing for me :-)
& Wasn't able to understand from a long time
@asmitalimbu3357 you're nothing but a Limbu (Nimbu/lemon in Marathi ) :p
@asmitalimbu3357 Nepal is nothing but I'm from nearby Kathmandu border only!
Both ma'am taught good and 2nd ma'am well explained
This is very usefull for everyone who is writting comption exam
count of "nothing but" = 100+ ... 🙈😁
25 times in 8.37 mins
is nothing but
85 times in whole video 😁😁
😂
😂
For 5th question just use average speeed=upsream*downstream/speed in still water. Apply the averag speed in formula spees=dist/time. U will get 4.8 as answer. Divide it by two. 2.4 km is the answer
Thank you so much!!!!!
1st ma'am teaches better than 2nd ma'am!!!!!!
1st ma'am, you should teach every lecture!!!!!!!
Thankyou respected madam for easing our efforts 🙏..very thankful for ur efforts
I really love the way you teach
Nothing But ... 😊 Great 👍
Legends are watching in 2024😂
Yes I am 😢😂
Preparing for cpo🤣
For ugc net 😢
At least you're too early. I'm watching this before the exam date
Yes I am the 😢 😂😂

=> 18+X= 3(18-X) , where X is the speed of stream resulting 9km/hr.
Yes I got the same
Sorry mam I couldn't concentrate on subject 😭....my eyes on your beauty 😭
I love the way you teach...
Wonderful✨😍 lecture.. Tysm mam
MAAM I CAN UNDERSTAND THE CONCEPT AND UR TEACHING.BUT LITTLE BIT SLOW WOULD BE COMFORTABLE TO UNDERSTAND.
Mam I really interested to you are lecture. I feel like a I am in class room. 😊😊😊😊
Mam at 13 there is no question of upstream I think time at still water=3*(time at downstream )
Is just me or it looks easy here but becomes confusing when it's time to calculate alone offline 🤦🏾♀️
Thanks for your help ❤
Super teaching ❤😊
these qns are now NOTHING BUT as simple as that 😁....................
Please do a video on partnership topic...khin aur se samjh ni Ara..u teach so well👌🏿
Mam you are looking beautiful 😍😍❣️❣️😘❣️😘😘
Nice explaination. ❤❤❤❤❤❤❤
Area,perimeter,volume ,surface area cheyandi mam please
Thank to both of you...
U r my one of the crush.🥰🥰🥰. U r looking so pretty since 2017. And also u r lectures are so easy to understand. Thank u. aiwarya
She's your crush and you don't even know to spell her name....thats amazing ....lol
😃
😄
Anyway she looks nice
thank you so much ishu mam .....i like your teaching style
I love you so much mam you explained me very well
Nice madm. Am understanding the concept well after listening to Ur classes. Give us more and more lectures. Tqsmmm for your efforts ☺
Thank you sister..... This really helped me a lot 😘
In the question where how far is place is ask. I think distance should be half of 2.4km . because in upstream and downstream same distance travelled in two times. Isn't it?
yes i agree with you
Very very nice 💥
What a surprise madam, after long time you made a video!!!
I like the way you teach.. 🙂
Thanks mam... Great work keep doing...pls teach RRB NTPC SYALLABUS Mam
Thanks a lot.
Love u mam ur teaching methods very effective
Thank you madam....
Superb mam thank u
Do icet syllabus videos sir. ....
Mam please make a video on rank permutation
It is nothing but you are genuis
thank you so much ma'am it really helps a lot ☺
Maam make video on work and time ?
@Luis Forest its paid.
Nyc video
9:54 how is the answer 2.........50 is positive and 2 is negative right
X2+48-100=0
(x+50)(x-2)=0
X+50=0. X-2=0
X=-50 x=2
So x=2 is answer
teaching and knowledge is just awesome... hope you continue for a long time and ALL THE BEST......
Thanks a ton
Downstream speed is thrice so lets take it as 3x
Speed in still water+speed of stream=downstream speed
So, 18+x=3x
2x=18
x=9 kmph
Thanks
Good.....tq madam
Hi dear ❤️ so nice 👌
Your teaching way is awesome
And your concept also.
What is 'a' and 'b' denoting? As 'u' and 'v' denoting speeds?
Bahut dino ke bad
Excellent experience mam😍
Nothing but..... Thanks
Miles need to be converted to km?
Nice.....
Very nicely explained 🥺❣️
Need only aieswarya She can teach fluently
Thank you teacher!
nothing but help me a lot
You teach well ma’am, pls try to use “nothing but” less
man in second problem , 17 km/hr, u don’t convert into m/s ? It’s right or it’s ok
Madam your class nice,,but going fast..
wow! 1st comment .Thanks mam
at first the explanation is great but next when teacher changed she messed up all the things
Can we add downstream speed and velocity speed ?
Nice 🥰
Superb mam u explanation and you are soo good..thank u mam
Ur video is very useful for us.. Thanks... Can u plz provide its pdf also?
Good English better solved
Mam a sincere request.. please solve previous year upsc csat and make.a separate serious 🙏🙏🙏🙏🙏
Try unacadamy for upsc level
It's just a basic level problems only solve.. upsc ask so many tricky questions.
Give response to my love actually I really really love you so much 😭 😭😭😭 Mera waqat nehi hai ki Mai apko sadhi karu but after die I need you 🥺🥺
Great mam
🥺🥺🥺🥺🥺🥺😭😭I love you maam I really love you So much 😟😭😭😭😭😭😭
Hello mam, what's your name ??? 🤗🤗
Mam I am preparing for mnc like tcs, Infosys, wipro, cts and sooo. This class are enough to crack the aptitude test.
is it enough bro??
Tq broo
@@le31hareeshsureddy82 bro I asked you is it enough to get into the aptitude round
O sorry bro
I am also asking nro
Please don't hide the board mam 😊
Can you explain LCM and HCF problems mam
thanks mam
I'm deaf
Y u using x method sometimes... You only explain me very length process...like rs agarwal methods...m plss teach me ....in shortcut
I’m struggling to understand the logic behind this. :((( Perhaps you might want to discuss how the formulas are changing in every question?
A Boat going upstream takes 8 hours 24 minutes to cover a certain distance, while
it takes 5 hours to cover 5/7 of the same distance running downstream. Then what is
the ratio of the speed of boat to speed of water current?
solution please
11:1
The speed is in km/hr.
Should i convert it to m/s ?
5:20
Leave that point itself Just check your options if it is in m/s or Km/hr and take the next steps accordingly. As this pattern is more often in govt exams you have to be in this way.
AT 08:17 the distance is in miles not in kilometers
Nothing but 🤙caller tune
Please consider the units of
answer
9:27 nostalgia 😏
☺☺☺
Still water has speed of 10m/h then why it is called still water.
Water always moves downwards then why still water speed is not called D's' speed.
Its speed of ‘BOAT’ in still water.
Is it enough for exam
Very big
mam can you also do time and work videos
😂 u remind my commerce sir.... Venki...
Hi this is sai miss @Ieshwariya garu whatever you explained is nice but i didn't understand because the way telling the point is not that much of impact or not reaching and not understanding try to give a proper way of explanation about the concept
first you said that speed of the boat is "a" and Speed of stream is "b"
then you speed of the boat is 1/2(a+b)
how can a=1/2(a+b)?????
