if M person r buying a thing costing D$ each,, if 3 person get away,, how much each person has to spend so that total expenditure is same ???
Read Solution (Total 4)
-
- thing costs D$ for each person.so total cost for M persons is MD$.
now no. of persons=M-3
let the cost for each person be x $.
therefore, x(M-3)=MD
or,x=MD/(M-3) - 10 years agoHelpfull: Yes(31) No(2)
- m person = d
so
1 person=d/m
if 3 person are get away then 3d/m are divided into m-3 person.
so 1 person =3d/m(m-3)
so 1 person total overhead=d/m+3d/m(m-3)
by solving we get d/(m-3) - 10 years agoHelpfull: Yes(8) No(1)
- Total expenditure of M person = MD
Total expenditure of M-3 person = MD
So, Per head increase in expenditure = (MD/M-3)-D = (MD-(MD-3D))/(M-3)
= 3D/(M-3) - 10 years agoHelpfull: Yes(3) No(1)
- no of persons=m
each person is contributing $d
now 3 persons are away
$3d should be shared among (m-3) persons
(i.e)3d/(m-3)+d
=md/(m-3) - 10 years agoHelpfull: Yes(2) No(0)
