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
Select the correct option: A) 3D/(M^2-3M) B) 3D/(M^1-3M) C) 4D/(M^2-3M) D) 2D/(M^2-3M) E) 3D/(M^2-M)
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).   3D/(M^2-3M)NSWER:3D/(M^2-3M)
