Rectangular tile each of size 70cm by 30cm must be laid horizontally on a rectangular floor of size 900cm by 600cm,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: Choose the most appropriate option: A) 50 B) 70 C) 80 D) 90 E) 100
