Solution

## The correct option is B Only IBy merely knowing the area we cannot find the number of tiles as some tiles may not fit exactly on to this floor Statement III provides us with dimensions that area exact multiples of the size of the tiles This shows that the tiles can fit exactly We can thus answer the question using statements II and III In other word statement I can be dispensed with
