M men agree to purchase a gift for Rs. D. If 3 men drop out how much more will each have to contribute towards the purchase of the gift? Choose the most appropriate option
A) D/(M-3)	B) MD/3	C) M/(D-3)	D) 3D/(M2-3M)	E) None of these
Initial contribution = 3D/(M2-3M)/m   After 3 men drop out, then the contribution = 3D/(M2-3M)/M-3   the extra amount to pay = (3D/(M2-3M)/m-3)-3D/(M2-3M)/m   =3D/(M2-3M)(m-m+3)/)(m^2-3*m)   = 33D/(M2-3M)/(m^2-3*m)   ANSWER:3D/(M2-3M)
