Examples: Unitary Method Video Lecture | Mathematics (Maths) Class 6

hello friends this video on ratio and
proportion part 14 is brought to you by
exam for calm no more fear from exam so
let us look at some of the questions and
how we apply unitary method to solve
them question number one eat the ants
appease 1,500 in ten days how much will
she earn in 30 days now another
important thing that you should remember
is you first should read the question
and find out that what is that value
which you need to calculate for example
here you need to calculate how much
money does she earn in 30 days right so
you have to find out in the unitary
method you have to find out the value of
one unit first so that what is that one
unit that is how much does she earn in
one day because here it is given that in
10 days she earns rupees 150 now
whichever value you have to find out you
keep that parameter on the right-hand
side so these are just tips which I am
giving you so by reading the question
you've got to know that money is
something which you need to calculate
that is how much money is she earning so
let's keep the money part on the right
hand side so the given statement is ten
days she's earning rupees 1500 so let's
find the value of one unit that isn't
one day how much she be lon
shaving on routines of 1,500 divided by
ten therefore in 30 days how much will
she on she will earn rupees 1500 divided
by 10 into 30 so this would be equal to
forty four five zero zero zero divided
by ten that is equal to rupees 4500
question number 2 China pays rupees
7,500 as rent for 3 months how much does
she has to pay for a whole year
if the rent per month remains the same
so here what do we need to calculate
again we need to calculate the money
that she has to pay right so the given
statement is this we will try to keep
money on the right
site so for three months China pays
rupees 7,500 so for one month how much
she will be she will pay rupees seven
thousand five hundred divided by three
so for one whole year one year consists
of how many months one year has 12
months
therefore for 12 months she will have to
pay rupees 7,500 by 3 into 12 so three
fours are 12 so when you multiply this
you get your B's 30,000 question number
three cost of four dozens bananas is
rupees 60 how many bananas can be
purchased for rupees twelve point five
zero so here what do we need to find out
we need to find out number of bananas
now given condition is cost of four
dozen bananas is rupees sixty four dozen
bananas means how many bananas 4 into 12
because one dozen is 12 bananas so four
dozen would be 4 into 12 bananas so we
will keep the number of bananas on
right-hand side that means 4 rupees 60
we can buy how many bananas 4 into 12
bananas so you understood why we are
keeping the number of bananas on the
right hand side because that is what we
need to find out so four rupee one how
many bananas can we get 4 into 12 is 48
divided by 60 bananas
so therefore 4 rupees 12.50
how many bananas we we get 48 by 60 into
12.50 so now 48 by 60 12.5 0 can be
written as 1 2 5 0 divided by 100 so now
this is 12 forza 48:12 560 so here this
would be 5 to 10 by 5
five zero so this is zero zero will
cancel so this is 2 2 so 4 2 5 10 5
fights are 25 so this is 10 so when you
actually simplify this entire odd thing
so you get it as 10 so that means before
rupees 12.50 you would get 10 bananas
question number 4 Anish made 42 runs and
six overs and unmade 63 runs in four
overs in seven overs who made more runs
per over that means who made more runs
in one / / / needs one over
so let's write both of these Anish and a
loop so Anish has made 42 runs and six
overs and we want to calculate how many
runs we made in 1 over so we can say six
overs we made 42 runs therefore one over
he would make 42 by six runs so six
seven so 42 so that is seven runs now
let's do the same thing for a loop so in
seven overs one who made 63 runs
therefore and one over he would make 63
by seven runs so 7-9 to 63 that is nine
runs so looking at this we can see that
i noth made more runs / / so with this
we have reached towards the end of this
lesson on ratio and proportion and i
hope that this lesson would have helped
you and would have also helped you to
know how ratio and proportion is used in
our day-to-day life to compare
quantities so see you all in the name
