You are also wrong how long it "will" take to empty the tank not "it will be"..Don't find any grammer mistake just analyse the question and understand it that's what we want right!!
Hi, appreciate your efforts. It's very helpful. In this video while mentioning example for first formula xy/y-x, the question was shown "if the tank is full how long it will take to fill the tank?" A small request, please do check the question once.
Sister, your teaching is amazing 👌🏼😇😌 Here I noticed a mistake in the first problem. I think the correct question should be, 'If the tank is full, how long will it take to empty the tank?' Am I right ?
Super shortcuts. I saw the video and understand very easy. I saw two more topics also and understand very easy. Thank you so much. But I have a doubt.. 1. Two pipes A and B can fill a cistern in 12 minutes and 15 minutes respectively but a third pipe C can empty the full tank in 6 minutes. A and B are kept open for 5mins in the beginning and then C is also opened. In what time is the cistern emptied? Plz solve the above questions 👆
@@sharathchandra6349 P : 24 hrs and Q : 32 hrs P in 1 hour : 1/24 and Q in 1 hour : 1/32 x = time when both P and Q run together P in x hour : x/24 and Q in x hour : x/32 Then: x/24 + x/32 = 1 [ Equal to 1 means full tank ] But since Q runs for 16 hrs and P needs to be switched off early at lets say y hrs Then: y/24 + 16/32 = 1
Madam... In the first question of this video, there is a mistake in the last sentence of the question.. I.e tank is emptied in what time??? It's the correct sentence... Ok?
A cistern is provided with two pipes A and B. A can fill it in 20 minutes and B can empty it in 30 minutes. If A and B be kept open alternatively for one minute, each, how soon will the cistern be filled?
I think the first Question is similar with the part 1 last question "A pump can fill the tank 2 hrs ,if leak then takes 7/3 hrs..." but used formula is different. anyone can please make me clear the dought ?
A cistern has 3 pipes A,B and C. A and B can fill it in 3hrs and 4 hrs respectively while C can make it empty completely in 1hr.If the pipes are opened in order at 3,4 and 5 pm respectively at what time will the cistern be empty???? short cut ans solution
The first question of lesson 2 and the last of lesson 1 is same,but different formula,, either of the formula can be use but here it is impossible but the question is same,.... clear it Ma'am you make me trouble
Two pipes A and B can fill a cistern in 37(1/2) minutes and 45 minutes respectively. Both pipes are opened. The cistern will be filled in just half an hour, if the B is turned off after: I couldn't solve this by using the formula which u hv told...plz explain this sum
It seems like the tank wasn't filled coz it was mentioned that it would be filled in 24hr,32hr but we wanted the tank to be filled in 16 hours coz both were opened together to fill the tank so the question was correct.....that's just my guess don't show me ur hatred if my assumption was wrong or my sentence formation 😅

you are nothing but the sweetest teacher 😁

I do nothing but love ur teaching mam 😂
last line of question is wrong , it will be" how long it take to empty the tank"
Ss u r crct
exactly
Agreed
You are also wrong how long it "will" take to empty the tank not "it will be"..Don't find any grammer mistake just analyse the question and understand it that's what we want right!!
@@roopaliagarwal4767 its just a small mistake, it doesn't means she had mugged up. Look at her efforts
thanks you really saved a lot of time for me
please Explain From where such formulas were derived.
IT is Nothing but Mugging up.
Thanks madam for short understanding of formula.

That is to empty the tank
well thats are heavy mistake ....
I think its empty 😂
Yes.. it's for empty the tank
The last line of the question must be "How long does it takes to empty the tank".
yes
First problem in this video u solved for time taken to fill tank or to drine the tank
Sister, your teaching is amazing 👌🏼😇😌

Plz solve the above questions 👆
is the answer is 6.3 minutes approx ?
no need to go for formula simply x/24 +16/32 =1
Bro ,can explain this problem briefly.
@@sharathchandra6349 P : 24 hrs and Q : 32 hrs
P in 1 hour : 1/24 and Q in 1 hour : 1/32
x = time when both P and Q run together
P in x hour : x/24 and Q in x hour : x/32
Then: x/24 + x/32 = 1 [ Equal to 1 means full tank ]
But since Q runs for 16 hrs and P needs to be switched off early at lets say y hrs
Then: y/24 + 16/32 = 1

@@saurabhdagar9596 thanks bro!!
Well explained,to the point. Thanks
You did very well but some of more questions which cannot solve by this method , so please make a part-3 in pipe and cistern
Tqq mam...u r videos were very use ful to us.....tqq mam...plz upload so many videos on simole interest😀😀😀🤓🤓
awesome maam amazing , ur way of teaching is great , nd the english too is very fluent

6 minutes
1/20+ 1/30 = 1/12 [which is 12 minutes]
now since they are doing work every alternate minute
it'll become 24 minutes
Thank you so much 🙏🙏❤️❤️...
Mam this method is very use full two types are enough or any another type??
Please re look the first question.., Thank you
Mee teaching way chaala baagundi akka
matra

Your explanation is too excellent please Make video soon
What is the book that you can suggest for aptitude
Mam wow you explain 👌👌👌👌

Time saving video
When tank is full how can you fill the tank again??
mam,is there any more videos on this topic or is it the last topic.
Nice teaching
Mam,thanks for your kind support😍😍please make more videos on it..
your english is too good
Question from last formula u have showed:
if the 2nd pipe be turned off what will be the formula then?
(1- (total time to fill the tank)/1st pipe time taken)* 2nd pipe time taken
Please solve more questions on same some topics
please upload a video for email writing skills for To ,cc,bcc
I think such type of problem... you must explain in detailed.
Mam if they are asking 2nd pipe to be turned off then this formula will applicable or not
which ever pipe has to be turned off after some time needs to be taken as 1st pipe i guess...
You explain all well but why you make video on full concept. You make only 1 or 2 short video
i like how u use formulas. without formulas i can't think so much and solve problems :p thank you for these videos!
Thank you madam I have learn a lot
1st question we have to find how long it will take to empty the tank
Awesome mam..
And thank you so much
Madam ur accent is awesome... Idli sambhar utttaapam

i kindly to request to you please make video on time and work .
Thank you mam.

short cut ans solution
Let t be the time
(t/3)+(t-1/4)-(t-2/1)=0
If total fill filled time is not given then what we have to do..?
thank you!
Mam when the 2 pipe is closed means any change in the problem
Mam mind blowing ur class
The first question of lesson 2 and the last of lesson 1 is same,but different formula,, either of the formula can be use but here it is impossible but the question is same,.... clear it Ma'am you make me trouble
Two pipes A and B can fill a cistern in 37(1/2) minutes and 45 minutes respectively. Both pipes are opened. The cistern will be filled in just half an hour, if the B is turned off after:
I couldn't solve this by using the formula which u hv told...plz explain this sum
Let, x be time taken by B..
Then,
(x+1/2)/37.5 + x/45 = 1
If u solve that equastion then u will get answers... I.e x = 20(2/11). Ok?
ss me too
Mam please data interpretation and coding decoding k bhi lecture bniye naa please Mam hmare exam m aate h

amazing shortcut where you find this
Tqsm... Didi
In 1st question for XY/Y-X formula, y to fill the full tank ? What is the logic ?
Yaa...I guess the question is wrong....It's time taken to empty the tank..
well explained
Do a single vedio for one topic then its easy for us
ಚಲೋ ಹೆಳ್ತೀವಾ nice job
make videos on time and work ,please!!
Mam how to find the time taken by the leak to empty the tank.
In the first que it's not how much time to fill the tank...it's how much time to empty the tank!!!
Mam u rocks
U r mankind angel
thanks
madam plss make more videos on advanced level of each topic
For second question, what if question is to find second pipe close time
Astounding!!
Formulas kante concept wise ga explain chetse better...but ur effort good
nice and good
explain the proof of your formula in order to understand preciously
Please send simple method video on Time & Work.
mam please make a videos on topics 'machines and mins'
Error Spotted - 28 hrs to empty the tank. As the tank is already full.
Yaa
Teachers shouldn't be much beautiful like you ma'am. Bcz it's hard to concentrate on lecture ;)
Mam plss upload more questions
Using formula at instant of exam wouldn't help much. Traditional method or logic method
Excellent
How many formulas we have to remember
It seems like the tank wasn't filled coz it was mentioned that it would be filled in 24hr,32hr but we wanted the tank to be filled in 16 hours coz both were opened together to fill the tank so the question was correct.....that's just my guess don't show me ur hatred if my assumption was wrong or my sentence formation 😅
