Alligation & Mixture-Under One Minute Video Lecture - Banking Exams

hello students I hope you are working
day and night for Dad and other
competitive papers students let me tell
you here it's not only about your
intelligence but the knowledge of the
concept that you have learnt or the kind
of accuracy that you attain is only
something which helps you in the exam
rather it is a time that is spent per
question is of a great great
significance in case of CAD or other
such competitive papers the students
here the topic that I am going to
discuss is allegation and wilshire which
is one of the complex topics and if I
talk about your a preparation for that
very topic though this is a very
different kind of a topic that if you
see a question related to allegation who
may skip that question you may avoid it
or you may make a very very lengthy
equation to solve that question now
let's learn here with the help of a
actual CAD question that how can we
solve those questions
logically quickly along with the long
equation oriented method to answer that
the students just have a look at the
question now here is a question talking
about a dishonest dairy shop owner who
starts putting milk into a container
consisting of water here he would
withdraw 9 litres and replace with milk
and every time he will keep on doing
that after that finally a smart person
comes to know of that and at that time
the ratio is given to be 16 is to 9
my students now how do we solve that
questions now for this question
particularly this is a formula that you
apply now as per that formula students
you write the quantity left is equal to
the total quantity and then 1 minus N by
total quantity raised to the party where
n is the quantity withdrawn every time
the students here if I refer to the
question once again it specifies that
the ratio is 16 is to 9 for water to
milk this means water is 16 if the milk
happens to be nine now here students you
can say the quantity left will be
sixteen by twenty five of the total as
16 water and nine milk is there which
was also a part of the total this is
equal to the total quantity and then one
minus nine litres are we done every time
divided by X raised to the part two
because the process has done twice so
can you write the left-hand side as 4 by
5 raised to the path to X we can cancel
here only is equal to X minus 9 by X
raised to the power 2 we can cancel the
students and then we can solve it to say
4x is equal to 5x minus 45 and solving
that to get the value of x to be equal
to 45 litres so this 45 liters here
becomes your answer my students now
let's think about this question
logically can I say finally what is left
over is 16 by 25 and students do you
remember how many times you have done
this process you have done this process
two times so if you have done this
process two times you need to know that
this figure is the sphere of which
number no this is a sphere of four by
five this means the quantity left is
four by five every time if quantity left
is four by five every time you can say
you have withdrawn one by five every
time students and the question says 9
liters have been withdrawn every time so
students 1 by 5 of X on one hand is
equal to 9 on the other so you can
answer it
will become equal to 45 rice sweats so
this 45 here becomes your answer so you
can see whether you apply this approach
or you apply that approach the answer by
default remains the same students I hope
you all have understood it in order to
learn this concept as well as a few more
concepts through videos you should
register and hit bull's eye calm I hope
you would have really enjoyed it and
this will really help you in solving the
questions in a better manner thank you
happy loving
