it is this is a case of indirect
why it is a case of indirect it is a
case of
indirect variation indirect
variation because if machines
are increase then
it takes less time to complete the same
work
and in indirect variation k is equal to
x into
y it means 3 into 60
is equal to 5 multiply x
so 3 into 60 divided by 5 we got the
value of x
5 5 and the 5 5 to the 10 it means the
