Answer Posted / suchi teegala
let there are x no of persons
let each person's contribution be y
given each contributed an amount of y to get 300000
therefore , 300000/x=y
given that if they increase 50 rupees in their contribution
then the amount will i ncrease from 300000 to 325000
therefore , 325000/x=y+50
on solving the equations
xy=300000 and
xy+50x=325000
we get x=500
hence total no of persons are 500 is the answer
