A group of 3 friends staying together, consume 54 kg of wheat every month. Some more friends join this group and they find that the same amount of wheat lasts for 18 days. How many new members are there in this group now?

Answer:

Total friends = 3

Let us consider number of friends joined in a group be ‘x’ friends

We know k = xy

3 × 30 = x × 18

x = (3×30)/18

= 5

Joined friends = 5 – 3 = 2

∴ 2 new members joined the group.

"hello students and eeta your mass leader
tutor and
today's question is a group of three
friends staying together
consumed 54 kg of feed every month
some more friends joined this group and
they find that the same amount of wheat
last for 18 days how many new members
are there in this group now first of all
we let
new members number of new
friends or we can say members
is equal to x
and three friends consume 54 kg wheat in
every month
but now the
now the wheat lasts for 18 days
so we form a table between number of
friends
and between the time
so first of all the number of
days and the number of members
we write it this is number of members or
we can say
number of friends if number of
friends is three then time
which is in days then the 54 kg of feed
last
for 30 days but if new members add
so we let it be x then the feet consume
in 18 days so it is a case of
it is a case of
indirect variation
it is a case of indirect variation
because one thing
is increased then second is decrease if
number of
persons increase the number of days
decrease
in indirect variation
k is equal to x y
so 3 into 30 is equal to
x into 18 now we solve the equation
so 90 is equal to x
into 18 so 90 divided by
18 is equal to x so
18 and it means
x is equal to five that is the number of
new members
are five five new members
