10.4 minus 9.6 is o.8 .. O.64 kaise aa gaya
Sir you made a mistake in 9th question
Sir plz reply my comment
In 9th question total is 1080-455=625.x=625/3=208.3 is the ans.
Yes
Same here
yes this is the right answer
Ya correct
Yes it's 455 and he had mistakenly written it as 555
Great videos :),
but would like to point out one calc mistake at 36:55, 1080-290-165 = 1080 -455 = 625
yes
Can you please explain how to solve 28:49( question 7) with direct formula.
yes the ans is 208...=625/3
Time 50:54 , it is said that 10.40-9.6 = 0.64 whereas it should be 0.8, and following to that, it is said that 9.6-8.8 = 0.96 whereas it should be 0.8 too.... My doubt is that when both the differences come out to be 0.8 and 0.8 how can we take their ratio? As it will come out to be 1:1. Please let me know what has to be done in sums like these where the differences come out to be equal.
Bro, their is small mistake when we divide 146.40/15 then ans is 9.76 and solve it futher now ratio are different (2:3)
In the 9th sum
1080-290-165= 525 was taught by you .but I had a doubt on this by subtracting 1080-290-165 =625 ...this was I got

Best sir.. These lectures are more than enough for me to study.. The notes from these tutorials and the sums from these r alone more than enough for one to study for entrance exams bcoz what u have given is the base for everything sir.. Thanks a million lot and hats off to u and ur channel.. Kindly upload some basic math videos which relates for entrance sir.. Thanks sir 🙂☺

Q:5 Had a formula.... From X litres liquid we remove Y litre liquid and added same amount of water,And that continued N times....Then [X(1-(Y/X))^N] litres
Thanks it really works
Thanks for this!
😘😘😘😘😘
❤
5th problem can be done in this way also
4 lit of milk was taken and 4 lit of water added.that means 4/40=1/10 part of milk was taken from mixture. so 9/10 part of milk remained.this continued for two more times. therefore we can do it as 40*(9/10)*(9/10)*(9/10)=29.16
Thanku very much bro

Glad to know, Praneetha. Thank you for taking the time to come back and let us know. All the best! :)
Oh lord.... This was an amazing session. This topic was never going into my head,now I'm able to understand it. While listening to his lecture, a new dimension of my brain opened to understand
answer of 9th question is 208.333
your calculation mistake is there
yes, he wrote 555 instead of 455, otherwise it's correct and yes the answer is 208.33

First I had started with the random topic of this playlist I was unable to clear any topic clearly than in the 26th video of this playlist ma'am shared a png file so I referred that and also got motivated then came back to this playlist and now I am able to solve every question thanks team careerRide.
Question no 12 can be solved by another method, (15-x)10.40+(x)8.8=146.40 by solving this equation you can get answer x as 6kg
👍
Thank you very much
You should also reply to the doubts but it seems in such a way that you only like and respond to the appreciation of your videos.
At last in Q no 9 there is a mistake
It was written " 1080-525 "
But it had to be "1080-455"
208.33
Yea man... He needs a calculator.
@@skmgamer8214 yes dude

Thanks. Gudimetla! Stay connected and do share the video with your friends too :)
it's common sense that, if the price of three mixture is 180 rs per kg, and if the two of them is below 180 then the price of the third item should be more than 180, question no 9
Are you stupid? It's in Ratio. Not 1:1:1
It's really excellent, who all are using logic methods. It is very useful to me
Thanks a lot sir! The series is very helpful.
In qno:2 avg of 520+420=940/2=470,so if we will substract 520-470=50,420-270=50,ratio would be 1:1,plj correct me if im wrong
Thankyou sir .i had no background idea about this topic..after seeing your video i became perfect in this topic
Thanks, Pratibha! :)
Thank You So Much Sir..Careerride is always Helpful to me
Thankyou for the video ..is really helpful to prepare quant section for my placement nd bank exams . Do keep coming with more such useful content.
please make a video on Banker Discount also... Your Teaching way is awesome.
In question no 10 how you directly add ratio first at least you have to make their base same.
Add lecture are quite good
Leave me out of the hell of learning on my own though
U deserve a like 😅😅
Really awesome way of teaching...
Q no 5 can also solve by a this formula [x(1-Y/X)ⁿ]
What are the values of x, y, n
[40(1-(4/40)) ^3) ]
yeah where, X= Total quantity of Liquid,
Y= Quantity of liquid removed,
n= no.of times the cycle repeated.
Thanks..where did u learned that formula from ??

10th question logic was super thanks!! Overall good collection of questions.
Thank you so much Sir
You are covering almost all typical questions that are needed to be practiced
thanks a lot
it is really helpful
5th question can also be done by the formula (Initial Qty. - Qty. Withdrawn/ Final Qty.)n
(40-4/40)3 = (36/40)3 or (9/10)3 = 729/1000.
40×729/1000 = 4×7.29 = 29.16 litres.

Thank u
Sir in 12th question 10.40-9.6 is 0.8 and 9.6-8.8 is 0.8 but u have taken it as 0.64 and 0.96
146.4/15= 9.76 and not 9.6 thats where he has done the mistake
Exactly
Really helped me. Thanks.
Doubt in 12th question sir.. kindly check calculation. how 10.4-9.6 comes out to be 0.64 and 9.6-8.8 commes 0.96... plz reply
He is not solving it at the moment looks like copying from some other notebook.
He made mistake in 146.40/15, it's actually 9.76 and not 9.6.
So 10.4-9.76=0.64. that's how he got 0.64
HELLO SIR IN QUESTION NO 12 THE CALCULATIONS DONE ARE WRONG I.E 146.4/15=9.76
EVEN WITH 9.6 SIR DID WRONG CALCULATION
10.4-9.6=0.8
9.6-8.8=0.8

In 5th question since we are diluting the mixture by 10% in each go we can use 40x(0.9)^n = 29.16 {n=3 here} instead of the big sum.
How .9 came there ,please explain

Yes, Saumya but it is important to practice. You'll find a lot of practice sums on our website /www.careerride.com

That great, Vinay. Keep it up :)
Qtn no 9 is wrong soln it comes as 455 and then 1080-455--625 / 3=208..
Question 5 was what I was actualling in search for. It took my too much time, until you made me crystal clear for me.
It is wrong. Check the video of mixture by Dear Sir channel. It is in 2 parts, check out 2nd part. The first question is exactly like this but with different numbers. And they teach much easy and smaller formula for these type of question. And by using that formula you will realise the answer of 5th question here is wrong.
@@shiva999ful link please bro?
sir qus=12 ,146.4/15=9.6 not 9.72 is right 50:48
Simply use : quantity of pure liquid = x(1-y/x)n units
Amount of milk left after 3 operations
= [40(1-4/40)3] liters = (40 x 9/10 x 9/10 x 9/10) = 29.16 liters

Hello sir,
In question no 10.
Actually I'm not getting how exactly it happens. Can you explain and verify it by assuming some quantity.
Thank you.
You can either take salt or sugar
Average of Fraction is wrong there!!
Q 12 can solve in this way also
Assume quant 1 is x and quant 2 is y
Then x+y = 15 ----(1)
10.4*x + 8.8*y = 146.4 -----(2)
solving (1) and (2)
we get x=9 and y=6 which is the answer.

Q.no.9 -290-165=-455 not 555
Question no 12 again mistake in subtraction
yeah right
Don't go for finding any calculating mistakes
@@arpitgaurav4222 yes 10 liters is subtracted, should be added...
What the ans and explain it
Another way to solve Qn(10) : (hard)
consider 1 liter of all the type ;
let k1 : k2 be the amount of food mixed (ratio)
for k1 liter/kg type 1 food, amount of sugar k1x(sugar per liter of type1)
ie. k1x2/13 similarly salt - k1x 11/13
similarly for food 2
so.
Amount of sugar in
k1(2/13 +11/13) +k2(5/26 +21/26) = 7/39 + 32/39 (per litre)
equate sugar(left)---> sugar(right)
(11/13)k1 +(21/26)k2=32/39
similarly salt(left)---> salt(rgt)
k1(2/13) +k2 (5/26) = 7/39
solve for k1 and substitute in eqn and find k2 ....
final ratio would be k1 : k2 ---> 13: 26 or 1: 2

sir qus=12 ,146.4/15=9.6 not 9.72 is right 50:48
8)
(30 litres of water + amt of water to be added in litre) = 2/3(90 + amt of water to be added in litre)
simply,
(30+l) = 2/3(90+l)
90+3l = 180+2l
l = 90
amt of water to be added in litre = 90 litres
Thanks u so much for this, much needed
Thank You for the concept you have presented 🙏.. Others figuring out numerical mistakes meanwhile I concentrated on concept you have taught❤️❤️🙏🙏
Me the same
Please correct me if I am wrong. In 8th question, shouldn't the amount of mixture i.e. 90 L should remain same and only the ratio of acid and water should change. Hence, after the inversion of ratio, it will be 30:60, so 30L water should have been added.
Yes it can be possible but when they will say that amount of mixture is fixed and 90 L only . But when in question itself they say add amount of water added to mixture we can take meaning that amount of mixture is not fixed and we are supposed to add water in the preavailable mixture itself.
Excellent teaching sir......
However, Amazing sessions !!!! Thank you for the same.
Question No. 9 How it is 555 by adding 290+165
sir in question no. 5 you take so much time to slove it...pl give us short tricks because in exam we don't have that much time to solve this
there z a short trick for continuous operation of removal of milk 4lit and adding water 3times....use some short tricks....
Simply amazing
By saying This sum is also very easy you make us feel like dump 😅🤣
Not at all, Prashant. The only reason we keep reminding you that this is easy is so that you as a student don't get scared of any question. The only reason we don't do well math is - Fear. Throw it away, today. You'll excel. All the best :)
In Q's no 6 how do we consider that both of the glasses are same in volume?
Question wrong...not other glass ...the same glass...
awesome...thank u sir
In 6th question, we can directly say that in 18 parts of the mixture is 12 parts of jiuce and 6 parts of water, then the ratio will be 1:2. Isn't it right? Plz clear my doubt...
Thank you so much, video is really helpful.
In question no 9
There is some mistake in the calculations
290+165+3x=1080
3x=1080-290-165
3X=625 ( not 525 as calculated in the video)
X=Rs.208.33 /kg
yeah i too found that
There. Are lot of mistake
Yes many mistakes
In what proportion should water be mixed in a liquid of Rs 12 per litre, so that when it is sold at Rs 13.75 per litre,there is a profit of 25%?
Thanks a lot sir!
4question? 36 lt milk, so remaining 44 lt is water.
The new ratio we want is 75:25, ie water is remains same ie 25%=44. ( here we r increasing the amount of milk only, so the water amount remains same)
If 25%is =to 44 lt, then 75%is = to 25%*3 ie 44*3=132.
So we already have 36lt of milk, we need to add 132-36=96litre of milk.....
Super
It's good method
thank you bro super
Thnq bro simple explanation 😊
Sir, make a video on,,,problems on meeting of two trains
U explained very well sir
Sir, Is there any shortcut for 5th question, It becomes difficult to calculate if it was given i.e. repeated for five times.
In question 11 at 48.14 if 10 litre solution is replaced by adding pure honey..den it should be 57-5.7+10 right?
Right
It was just a sign mistake, but he did right although
Everyone trying to find mistakes but he's actually did perfect
32:36 y u took 60 as acid, we could have taken 30 instead?
If you are going for mixture and allegation please check out ratio and proportion first it's many concepts are used in mixture and allegation
