Answer / saravanan.p

Let 'x' be the number of perons in the group and let 'y' be
amount per head which they have to pay.
Then xy = 2400.
or y = 2400/x
Since two friends have forget the purse, x-2 persons should
share the total amount(2400).
If they share, they have to make an extra contribution of
Rs 100 to pay up the bill
That is x-2 persons should pay y+100 each
or (x-2)(y+100) = 2400
or y+100 = 2400/(x-2)
or y = 2400/(x-2) - 100
Therefore we have got two equations namely,
y= 2400/x and y = 2400/(x-2) - 100
Comparing these two, we get
2400/x = 2400/(x-2) - 100
Solving this we get
x^2 - 2x -48 = 0
or (x-8) (x+6) = 0
or x = 8 or x = -6
Since 'x' denote the number of persons, it should be
positive.
So, x = 8.

Answer / 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
