a group of friends goes for dinner and gets bill of Rs 2400
. Two of them says that they have forgotten their purse so
remaining make an extra contribution of Rs 100 to pay up
the bill. Tell the no. of person in that group
Answer Posted / rajkumar
let the no.of persons=x
then
100(x-2)+(x-2)*2400/x=2400
100x-200x+(2400x-4800)/x=2400
.
.
.
.
==> (x-8)=0 or (x+6)=0
finally either x=8 or -6
therefore the no.of persons = 8
