Rectangular tile each of size 25cm by 65cm must be laid horizontally on a rectangular floor of size 150cm by 390cm,such that the tiles do not overlap and they are placed with edges jutting against each other on all edges. A tile can be placed in any orientation so long as its edges are parallel to the edges of floor. No tile should overshoot any edge of the floor. The maximum number of tiles that can be accommodated on the floor is:\nOptions:\n(A) 50\n(B) 40\n(C) 25\n(D) 36\n(E) 45 Hmmm, my stream of consciousness:

Area of tile = 25*65 = 1625\nArea of floor = 150*390 = 58500\nNo of tiles = 58500/1625 = 36\nSo, the no of tile = 36 So, the answer is (D).
