Answer 1

Answer: (B)

the question can be answered by using either statement alone.

Answer 2

Width of floor = 4 m and side of square tile = 0.25 m.
Now, to find the number of tiles required we need to divide the area of floor by area of tile.
A): Length = 12 m, thus area of floor = 48 sq. mt Hence, this statement is sufficient.
B): Area of floor = 48 sq. mt Hence, this statement is also sufficient
The correct option is (B): If the question can be answered by using either statement alone.
