m men agree to purchase a gift for rs D. if three men drop out how much more will each have to contribute towards the purchase of gift

• Additional amount = D/(m-3) -D/m = D*(1/(m-3) -1/m)= 3D/(m*(m-3))

• 3D/((M^2)-3M)
  
  Each of M men have to contribute = D/M.
  If three men drop then each of remaining men have to pay = D/(M-3).
  Therefore after 3 were drop each have to contribute = [D/(M-3)]-[D/M].
  i.e., 3D/(M^2-3M).

• total amount = d
  amount for each men = d/m
  now 3 men drop out, so amount = d/(m-3)
  answer is 3d/(m(m-3))
